Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command npm-launcher/bin/dchub-mcp-server.mjs:25, [пакет] bin/dchub-mcp-server.mjs:25

const child = spawn(process.execPath, args, { stdio: "inherit", env: process.env });

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

grid

get_grid_data

Use this when the user asks for live electricity grid data (power demand, fuel mix) for one grid: the 7 US ISOs (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE), TVA, BPA, 40+ US utility balancing authorities (e.g. AZPS, SOCO, DUK, FPL, or a city: PHOENIX, ATLANTA), Canada (IESO, AESO, HYDROQUEBEC), Great Britain (NGESO), any ENTSO-E bidding zone (EU_DE_LU, EU_FR, EU_NL ...), Taiwan (TAIPOWER), Japan (OCCTO), South Korea (KEPCO-KR), Brazil (ONS), Australia (AEMO) or Singapore (EMA). US ISOs and EIA regions return EIA hourly fuel mix, demand and the 24h curve; other grids return each feed's newest reading per metric, each with its own timestamp. For PJM it also returns installed_capacity_mw: EIA-860M installed generating capacity (net summer MW of operating generators for the report month in installed_capacity_mw_period). That is not PJM committed capacity, which is listed in licence_withheld with no value. Raw telemetry for one grid; do NOT use for power-availability, time-to-power or interconnection-queue analysis (use get_grid_intelligence), nor for retail/gas pricing (use get_energy_prices). To rank many grids at once use get_grid_scoreboard.

get_grid_intelligence

Use this when the user asks about grid capacity, power availability, headroom or time-to-power in a US ISO (PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE) or a market's grid. Returns live demand, fuel mix, queue depth, DCPI excess-power and constraint scores, time-to-power, reserve margin. avg_time_to_power_months and avg_queue_wait_months are DIFFERENT measurements; quote the one you mean. With a free key, a few full briefs a day; keyless gets a trimmed preview. Unlimited needs a paid key. Ex: "PJM headroom for 200 MW?" iso must be a US ISO (ERCOT, PJM, CAISO, MISO, SPP, NYISO, ISO-NE); other codes return region_not_covered. Free = preview.

get_grid_scoreboard

Use this when the user asks how power grids compare: demand, fuel mix or renewable share. GLOBAL grid scoreboard — 9 US grid operators (the 7 US ISOs PJM, ERCOT, CAISO, MISO, SPP, NYISO, ISO-NE, plus BPA and TVA) + Great Britain (NESO) + the European bidding zones (Germany, France, Netherlands, Italy/Milan, Spain, Poland, Switzerland, Portugal, the Nordics + Central/Eastern Europe — via ENTSO-E; the exact live-vs-configured count is in counts_basis.eu_zones_live / eu_zones_configured, measured per call rather than asserted here) + Taiwan (Taipower) + Japan (OCCTO areas) + South Korea (KPX) + Brazil SIN (ONS), ranked side-by-side on each feed's LATEST PUBLISHED reading: renewable share %, gas share %, full fuel mix (gas/nuclear/coal/wind/solar/hydro MW), and demand. ★FRESHNESS IS NOT UNIFORM and every row says so: each carries mix_period, mix_age_hours and freshness_basis. The US rows come from EIA hourly RTO, which publishes the FUEL-TYPE BREAKDOWN several hours behind aggregate demand — an overnight mix reading is routinely 18-24h old (it will show near-zero solar) while demand on the same row is ~1-2h old. Answers "which grid is cleanest right now", "how is ERCOT doing at this moment". Try: get_grid_scoreboard. Full guide: read resource dchub://tool-guides/get_grid_scoreboard

grid_transition_radar

Use this when the user asks where new grid headroom for data centers is emerging. Returns the US markets + ISOs with the strongest near-term emergence signal (BUILD verdict + excess-power headroom + short time-to-power), an ISO rollup, and a grid-headroom leaderboard. With a paid key, also the transition thesis: which ISO is opening up and why. The predictive counter to retrospective "where capacity landed" reports. Answers "where should I be looking next", "which market is about to become buildable". Try: grid_transition_radar max_months=24. Do NOT use for the current ISO queue snapshot (use get_interconnection_queue) or a present-day market ranking (use rank_markets); this is the forward-looking emergence radar.

market

get_market_context

Use this when you need a whole data center market briefing for your context window — one call returns a token-budgeted context pack for a data-center market: DCPI verdict, power & grid facts, the Claude-written 12-month outlook, M&A deals, construction pipeline, operator footprint, transaction comps, risk factors, and top news — each section with its own token count, as_of timestamp, and citable URL, greedily filled in that priority order under your max_tokens budget. Example: "Brief me on the Columbus data-center market" — get_market_context market=columbus max_tokens=4000. Params: market (required, market slug e.g. northern-virginia — valid slugs come from rank_markets); max_tokens (optional, 200-8000, default 4000). Returns {sections:[{id,title,text,tokens,as_of,cite}], used_tokens, omitted}. Do NOT use for a single metric (use get_market_dcpi_rank), the raw structured metric set (use get_market_intel), or cross-market ranking (use rank_markets); this is the narrative briefing pack. Cite "DC Hub (dchub.cloud)".

get_market_dcpi_rank

Use this when the user asks where a data center can get grid power, how fast, or whether a market is a BUILD, CAUTION or AVOID (e.g. "Where can a 100 MW data center get power fastest?"): DCPI scores 300+ markets daily on Excess Power and Grid Constraint, verdicts CC BY 4.0 after 30 days. DCPI rank for one market: BUILD/CAUTION/AVOID verdict, 0-100 composite_score (verdict-aware), excess_power_score, constraint_score, time_to_power_months. INCLUDES a `narrative` block with a ~100-word analyst read on the market, quote it directly with attribution to DC Hub. Use to answer "should I build here?" with structured reasoning + ready-to-cite prose across 300+ scored markets worldwide. Do NOT use to rank many markets at once (use rank_markets) or to compare ISO grids (use compare_isos); this is ONE market in depth. Verdict and composite score are free; numeric sub-scores and the narrative come with the DC Hub plan that includes every tool. market_slug is required: get it from rank_markets. 404 = unknown slug. Returns the build/constrain verdict, not raw stats.

get_market_intel

Use this when the user asks about a data-center market (metro supply, operators, pipeline, pricing): facility count, tracked MW, status mix, top providers, recent facilities or lease pricing. Pass market as a slug (e.g. northern-virginia). Returns stats, by_status, top_providers, recent_facilities, market_pricing (quote its basis). Verdict: use get_market_dcpi_rank. Keyless: a trimmed preview; a free key gets more. Ex: "1 MW colo price in Los Angeles?" Get the market slug from rank_markets or get_market_dcpi_rank; 404 = unrecognised market, use one of those slugs.

set_market_alert

Use this when the user wants alerts on a data center market's DCPI power score: subscribes to movement alerts (free with a key) — get notified when its Excess-Power / Constraint score moves. On the free tier, email alerts are delivered to the email your human bound via bind_email (call bind_email first; the destination is forced to that address). Set channel="email". Webhook delivery (channel="webhook" + destination=<https URL>) needs a paid DC Hub plan. Lets an agent MONITOR markets, not just query them. Answers "tell me when this market moves", "ping me if Northern Virginia’s power score changes". Try: set_market_alert market=northern-virginia channel=webhook destination=https://hooks.example.com/dc. Do NOT use to read a market right now (use get_market_dcpi_rank); this SUBSCRIBES to future movement.

gas

get_gas_economics

Use this when the user asks what behind-the-meter gas power costs in a US data-center market: Henry Hub spot, regional basis differential, and the delivered industrial + electric gas tariff ($/MMBtu), each with its own source label. Pass market=<slug> (e.g. "northern-virginia", "dallas", "phoenix"). AZ, GA, FL), never a substitute price; if the backend switch is ever turned off again, `gas_to_grid_status` carries that reason. ★ DO NOT COMPARE a $/MWh published before 2026-09-27 with one published now — each surface then picked the price its own way, up to 5.5x apart. Do not derive a $/MWh yourself from the $/MMBtu layers for a withheld state without saying that you did. Do NOT use for the electricity grid fuel mix (use get_grid_data).

get_gas_index

Use this when the user asks which US states suit gas-fired data center power: the Data Center Gas Index (DCGI), a per-state score. ★ DO NOT COMPARE a DCGI figure published before 2026-08-08 with one published now — they are different indices; the full record is at /api/v1/dcgi/methodology under `corrections`. A state that cannot be priced comes back verdict UNSCORED with dcgi null and an `unscored_reason`, never a placeholder score, so treat UNSCORED as absence and not as a low score. `gas_price_series` names which EIA series answered each state. Gas-fired $/MWh figures, withdrawn the same day for a separate defect, were republished 2026-09-27 under one burner-tip price rule (see get_gas_economics). Use get_gas_intelligence for pipeline, operator and parent-midstream data.

get_gas_intelligence

Use this when the user asks about gas-fired or behind-the-meter power economics for a data center in a US state — "is gas power cheaper than the grid in Texas?", "what is the gas access + pipeline situation in Virginia?". The GAS analogue of get_grid_intelligence: fuses the Data Center Gas Index (DCGI), live Henry Hub, gas-to-grid $/MWh across heat-rate scenarios, pipeline-operator presence, and the live grid gas share into one per-STATE brief. Params: region (US state code or name, e.g. "TX" | "Texas" | "Virginia"). Returns: {region, region_name, gas_access (pipeline counts + operators — PRESENCE not firm capacity), henry_hub_usd_mmbtu (live), basis_usd_mmbtu (synthetic-labeled), delivered_price_usd_mmbtu (null where the tariff table is sparse — surfaced honestly, never fabricated), live_grid_gas_share_pct, pipeline_presence (operators + parent midstreams), data_basis (per-field provenance/confidence), omitted_no_fabrication, dcgi_status, gas_to_grid_status}. A $/MWh published before 2026-09-27 is not comparable. `dcgi_status` and `gas_to_grid_status` carry the current state of each — read them rather than assuming both moved together. DO NOT quote a DCGI score cached before 2026-08-30 or a $/MWh cached before 2026-09-27.

analyze

analyze_parcel

Use this when the user has a land parcel for a data center site: structured read of its boundary — pass your own GeoJSON Polygon/MultiPolygon, OR just lat+lon and DC Hub finds the containing parcel in its HOSTED parcel-boundary layer (free county/state GIS polygons, covering a set of priority data-center counties in VA, IL, TX, OH, UT, OR, IA and WY; a point outside it returns parcel_not_covered with the analyze_site preview + the coverage list, never a guess). Returns _entity=parcel_analysis: geodesic total_acres, a per-member acreage breakdown, a contiguous flag, representative_point = the centroid of the LARGEST-area member (never the multi-part geometric center, which can land off-parcel on a highway median or river and poison every point-keyed read), and hosted_parcel {parcel_id, county, state, acres_per_source} when the polygon came from the hosted layer. Also returns a site_evaluation_handoff to pipe into analyze_site + get_water_risk at that anchor. Use when you HAVE a boundary or a point on a specific parcel and want it anchored + sized; for a general lat/lon site score use analyze_site; for the interconnection-queue survivor set use get_refined_queue (queue rows carry NO parcel identity, so they never auto-join to hosted parcels).

analyze_site

Use this when the user asks whether a specific site or coordinate works for a data center (lat/lon, or a market name for a market-level read). Returns a 0-100 composite, verdict, power/gas/fiber/market/risk sub-scores, nearby infrastructure and power cost; capacity_mw adds a capacity_context block and does NOT move overall_score. Keyless returns the verdict band and the power band, with the other factors named; a free key adds a few free full site reports each month; other scores and figures need a paid DC Hub plan. When a result is partial, show your user the human_message (or for_your_human) text and its link. Ex: "Score 33.45,-112.07 for 100 MW." Needs BOTH lat and lon in decimal degrees (else missing_coordinates); take them from get_facility or search_facilities.

compare

compare_isos

Use this when the user asks to compare two to four power grids side by side — fuel mix, demand, renewable/gas share, and for the US ISOs interconnection-queue depth and time-to-power — in one call instead of N sequential get_grid_intelligence calls. Example: "Compare PJM vs ERCOT vs CAISO on gas share, renewable share, and queue depth right now." — compare_isos isos="PJM,ERCOT,CAISO"; "ERCOT vs AESO vs EU_DE_LU" also works. Params: isos is a comma-separated list (2-4 max): any of the 7 US ISOs ("PJM" | "ERCOT" | "CAISO" | "MISO" | "SPP" | "NYISO" | "ISO-NE"), TVA, BPA, a US utility BA, or a non-US grid (IESO, AESO, HYDROQUEBEC, NGESO, EU_<zone>, TAIPOWER, OCCTO, KEPCO-KR, ONS, AEMO, EMA); non-US and non-ISO rows carry null DCPI and queue fields (not tracked, not zero). Returns: {isos[], comparison:{<iso>:{demand_mw, generation_mix_pct, renewable_share_pct, gas_share_pct, constraint_score, excess_power_score, avg_time_to_power_months, avg_queue_wait_months, queue_depth_gw, retail_price_cents_kwh}}, as_of}. ★avg_time_to_power_months (DCPI per-market estimate, ISO-averaged) and avg_queue_wait_months (proxy from live queue DEPTH) are DIFFERENT measurements — quote whichever you mean by name.

compare_sites

Use this when the user has 2-4 candidate data center sites and asks which is best. Pass locations as "lat,lon;lat,lon" and optional capacity_mw. Returns each site's analyze_site scores side by side plus a recommended winner and why. Keyless returns each site's verdict band and power band, with the other factors named; a free key adds names and counts without figures; scores and figures need a paid DC Hub plan, as does the pick. Ex: "Phoenix vs Ashburn for 50 MW?"

facility

get_facility

Use this when the user asks about one data center facility: name, operator, address, lat/lon, power capacity (MW total/used), cooling type, fiber providers (count + carrier list), commissioning year, status, the DCPI verdict for its market, and peer facilities nearby. Answers "who operates this data center and how big is it", "how many fiber carriers are in that building". Try: get_facility id=equinix-dc1-ashburn — or get_facility slug=digital-realty-digital-realty-iad38-ashburn-5754e62d. Returns ONE facility in full; do NOT use to search or list many facilities (use search_facilities). Needs a slug or id from search_facilities. 404 "not found": re-run search_facilities. Gated: give human_url to your human.

get_facility_risk_delta

Use this when the user asks how a data center facility's (or its market's) power risk changed recently — "has this site gotten riskier lately?". Returns the REAL DCPI market-health delta (excess-power score change over the window, direction improving/worsening/flat) from DC Hub's history-preserving daily snapshots. INTEGRITY: only DCPI market-health has a short-term temporal series; the site-hazard dimensions (FEMA disaster / USGS seismic / NOAA climate / WRI water) are DECLARED static (they don't change week-to-week) with a pointer to the point-in-time tool — never a fabricated week-over-week delta; no snapshot history → coverage:unavailable. Params: facility_id (a discovered-facility id or slug) OR market (a market name/slug), since (e.g. "7d"/"30d", default 7d). Returns {facility, dcpi_market_health:{delta, now, direction, coverage}, static_dimensions{...}, summary}. For the current point-in-time risk (not the change) use get_composite_site_score / get_disaster_risk / get_climate_intel.

fiber

get_fiber_intel

Use this when the user asks about fiber routes, carriers or connectivity for a market: long-haul, metro, dark or IX routes. Filter by carrier, route_type, market. Returns GeoJSON routes: carrier, type, fiber count, lit capacity, distance. Free callers get a sample of routes, not the full set; the full set needs a paid key. Ex: "Zayo long-haul routes via Dallas." Filter by market (slug from rank_markets) or carrier. For one building use get_facility. Gated: give human_url to your human.

get_fiber_readiness

Use this when the user asks whether one data center site (lat/lon) is fiber-ready: near-net distance to a carrier-served facility, how many distinct fiber carriers are reachable, and whether there is single-carrier risk (no path diversity). This is the parcel connectivity answer engineering site-selectors screen on. Example: "Is this Loudoun County parcel fiber-ready and how many carriers can serve it?" — get_fiber_readiness lat=39.04 lon=-77.48 radius_km=50. Params: lat (-90..90, required), lon (-180..180, required), radius_km (search radius in km, default 50, range 5-200). Returns: {score 0-100 (null when not scored — see carrier_data_coverage), near_net_bucket ("on-net"|"near-net"|"acceptable"|"build-required"|"unknown"), nearest_carrier_km, carrier_count, top_carriers:[{carrier, distance_km}], single_carrier_risk (bool, null when not scored), fiber_coverage_km, verdict_short, carrier_data_coverage ("confirmed"|"none_in_region")}. IMPORTANT — "unknown" is NOT "bad": carrier presence comes from PeeringDB, which is global but thin outside dense US/EU metros, so DC Hub distinguishes "no carrier serves this point" from "PeeringDB does not describe this region".

intelligence

get_intelligence_index

Use this when the user asks how healthy a data center market is: composite score (0-100) aggregating supply/demand balance, vacancy, absorption velocity, fiber depth, power availability, and pricing trend. Returns the index value, percentile rank across the 300+ market set, 7d/30d trend direction, and underlying component scores. Answers "is this market healthy", "how does Northern Virginia look overall right now". Try: get_intelligence_index market=northern-virginia. Returns ONE composite health number for a market; do NOT use for the full market metric set (use get_market_intel) or to rank multiple markets (use rank_markets).

search_intelligence

Use this when you need meaning-based search over DC Hub's data center intelligence corpus, choosing corpora — industry news, M&A deals, discovered facilities, per-market DCPI narratives, press releases, announcements, permitting intel, construction permits, tax incentives and the capacity pipeline — returning the most relevant records with citable source fields. This is the agent-friendly alias over the SAME retrieval layer as semantic_search: same results, different call shape. It takes `query` plus short corpus names (news | deals | facilities | market_narratives | press | announcements | permitting | permits | incentives | pipeline); semantic_search takes `q` plus the full corpus names. Call ONE of them, not both. Params: query (required, natural language); corpus (optional CSV of the names above, default all); limit (1-15, default 8). BEHAVIOUR: read-only — it writes nothing, and repeat calls with the same arguments return the same records. ACCESS: works with no key, but anonymous results come back as a TRIMMED PREVIEW; the session X-API-Key hydrates full depth per key, and the free tier is capped per day (call claim_free_key once — no email — if you do not hold a key).

plan

plan_fiber_leadin

Use this when the user asks how to get diverse fiber into a data center site: plans road-following lead-in routes from a candidate data-center site to a carrier hotel / POP, with indicative build cost and a route-diversity read. Answers "can I get N diverse fibre routes into this site, how far, how much, and where do they share a corridor?". Example: plan_fiber_leadin from="250 Paringa Road, Murarrie QLD" to="20 Wharf Street, Brisbane City QLD" n=4. Params: from (lat,lng OR street address), to (lat,lng OR address — e.g. a NextDC/Equinix POP), n (1-6 routes, default 4), fibre ("720F"|"1440F"), bore_m (river/rail bore length in metres, optional). Returns per-route length_km + GeoJSON geometry, total_route_km, diversity {min_separation_m_midhaul, shared_street_km}, and indicative cost {capex_usd, opex_usd_yr}. INDICATIVE auto-routed road corridors — NOT engineered alignments; subject to survey, DBYD and carrier confirmation. Do NOT use for a single site-suitability score (use analyze_site) or fibre-provider footprints (use get_fiber_intel).

plan_query

Use this when you want to see the plan for a data center question without running it (execute_plan runs the same planner and returns the answers). Reach for plan_query only to review, log, diff or audit a plan before executing it yourself. Deterministic keyword routing over the tool registry — no LLM, no network, same intent always returns the same plan (free). Returns _entity=query_plan {best_tool, intent_confidence + workflow_confidence (dual 0-1: question-read vs executability), reason, planner_rationale, recommended_sequence:[{step, tool, depends_on, estimated_calls, why, args_hint}], execution_waves (steps grouped into concurrency waves), execution_strategy.parallel_groups, execution_estimate {estimated_calls, estimated_latency_ms, parallelizable}, alternatives (each with when + rejected_because), coverage_notes, matched_classes} plus a versioned `replay` (schema_version 1): planner_version, decisions:[{id, step, kind, status, decision, rationale, decision_confidence, depends_on}], rejected:[{id, tool, reason}], execution_graph:{waves, parallel_groups} — auditable and machine-readable, safe to log and diff across versions. Full guide: read resource dchub://tool-guides/plan_query

power

get_power_availability_timeline

Use this when the user asks when power will be available, or about time-to-power, in a US state: year by year. Composes: new generation coming online from EIA-860M monthly, split by confidence class (under-construction vs planned vs testing — never blended); scheduled retirements as dated subtractions; LBNL interconnection-queue depth as congestion context (NO delivery dates — the feed has none and most queued MW never completes). The one derived number, cumulative_firm_signal_mw, counts ONLY under-construction+testing minus retirements — speculative permitting-stage MW is shown but never folded in. Answers "when is new capacity landing in Ohio", "what comes online in Georgia by 2027" with dated, sourced, per-lane-vintaged numbers. HONESTY LINE: supply-side signals, not a load-interconnection promise — generation ≠ deliverable load, and utility study timelines / large-load tariff processes / substation-grain delivery are declared out of coverage in constraint_coverage rather than estimated. Try: get_power_availability_timeline state=OH. Do NOT use for the raw project list (get_power_pipeline), live headroom today (get_grid_intelligence), queue survivors (get_refined_queue), or where-to-build ranking (rank_markets / ai_capacity_index) — this answers WHEN, for one state.

get_power_pipeline

Use this when the user asks where new power generation is coming online (the forward supply pipeline) — e.g. "how much new generation is planned in Virginia / the Southeast / ERCOT, and when?". Planned, permitting, and under-construction generators NATIONWIDE from EIA-860M, INCLUDING non-ISO regions (TVA, Southern Co, Arizona PS, PacifiCorp, LADWP) that interconnection-queue feeds miss. Each generator has location (lat/lng), state, county, balancing authority, technology/fuel (solar photovoltaic, onshore wind, natural-gas combined cycle, batteries, nuclear), nameplate megawatts (MW), status (planned → under construction), and planned online month/year. Filter by state (2-letter, e.g. VA), ba (balancing-authority/ISO code, e.g. PJM, ERCO, SOCO, TVA), status (P/L/T=planned, U/V=under construction, TS=testing), or min_mw. Returns a summary (total planned MW, mix by technology + status) plus the largest projects. Answers "how much new generation is planned in Virginia and when does it land". Try: get_power_pipeline state=VA. Do NOT use for ALREADY-OPERATING capacity or grid headroom (use get_grid_intelligence / get_grid_data) or for data-center construction projects (use get_pipeline).

rank

rank_markets

Use this when the user wants a ranked list of data-center markets, including where a data center can get grid power (criteria="ai_ready", DCPI): top N by cheapest_power, most_capacity, most_operators, fastest_growing, best_overall, or ai_ready (where new AI load can land, per DCPI). Filter by region, min_capacity_mw. Returns ranked rows with score, MW and a slug for follow-ups; score is the sort value, not a 0-100 scale, and score_basis says what it is (ai_ready omits it and explains its composite in `methodology`). Keyless: a trimmed preview; a free key gets a few full lists a day. Ex: "Top 10 US markets, ai_ready." Returns market slugs to feed get_market_intel and get_market_dcpi_rank. limit 1-500; set projection=identity_only to save tokens.

rank_sites

Use this when you have enriched candidate data center sites to rank under constraints — the normalization contract that lets you compare sites across separate analyze_site calls WITHOUT dropping into code. Pass candidates you already enriched (each an object with lat/lng + metric fields like risk_resilience, water_stress, fiber_km — pull these from analyze_site + get_refined_queue and pass site_evaluation_handoff through untouched), hard constraints, and weighted objectives; get back _entity=ranked_sites: top_k ranked with rank, objective_score, per-field normalized{} (0-100 relative to the set), and normalization_basis. objectives use SIGNED weights: +weight maximizes a field (e.g. risk_resilience:1), -weight minimizes it (e.g. water_stress:-0.6, fiber_km:-0.4). constraints are hard filters, fail-closed on a missing field. Use for "pick the best N sites under constraints"; for one site use analyze_site; to get the candidate set first use get_refined_queue. CANDIDATE CONTRACT: candidates may be {candidate_id: "cand_…"} entries from get_refined_queue — frozen identity (lat/lng/capacity_mw/fiber_km/iso) loads from the mint, your metrics overlay the rest; expired/unknown ids are dropped AND declared in candidate_contract, never re-resolved.

save

save_site

Use this when the user wants to save a data-center site to track it. Needs a key (free, via claim_free_key); keyless returns auth_required. Save a candidate data-center site to your DC Hub account to track it across sessions. Give lat + lon (plus optional name, state, market, target_mw, notes). Returns the saved site id. Pass `market` and DC Hub snapshots the site's DCPI baseline at save time, so every later list_saved_sites / get_changes shows how ITS score and verdict moved since you saved it. Builds a persistent shortlist an agent can revisit + monitor — after saving, pass the returned id to set_site_alert so DC Hub emails you when that site’s DCPI/capacity/nearby-facilities move (no re-checking). Answers "remember this parcel for me", "keep this candidate so I can come back to it next session". Try: save_site lat=39.04 lon=-77.48 name="Ashburn parcel" market=northern-virginia target_mw=100. Do NOT use to read back the shortlist (use list_saved_sites), download it (use export_dataset), or score a site (use score_facility); this WRITES one site to your account.

save_to_shortlist

Use this when the user wants to keep a data center site on a named shortlist that survives across conversations (Phase 5 statefulness). Snapshots the site's objectives + its current percentile objective_score, so you can re-score it later against the evolving national baseline. Use to build a durable siting shortlist across days/weeks; the list is scoped to your API key. Pair with get_shortlist to re-score + see drift. MINIMAL call: save_to_shortlist(shortlist_name="my-targets", site={site_ref, lat, lng, capacity_mw}) — objectives are optional. If you DID rank the site (analyze_site / rank_sites), pass those metric fields inside site and your objectives map too, and the re-scoring reuses them. Requires an API key so the list is private to you and survives to your next conversation: call claim_free_key first if you have none.

shortlist

get_shortlist

Use this when the user wants to see a saved data center site shortlist. With refresh=true (default) each site is RE-SCORED against the current national percentile baseline and returns saved_score, current_score, and score_delta_since_saved — so you see whether a site slipped because IT changed or the POPULATION did. The reliable way to maintain a siting campaign across days/weeks. Scoped to your API key.

set_shortlist_alert

Use this when the user wants a drift alert on a saved site shortlist so you can stop polling and be notified when a site's national standing moves materially (Phase 5). Fires when any site in the shortlist has current percentile score < percentile_below OR score_delta_since_saved < delta_below (e.g. -8 = dropped 8 points vs when saved). Evaluated after each daily baseline refresh; delivers via webhook and/or email. This is the "wake me when it matters" loop for long-running siting campaigns. Scoped to your API key.

site

set_site_alert

Use this when the user wants an email watch on a saved data center site (free with a key) — DC Hub emails you when that site’s DCPI score, grid capacity, or nearby facilities move, so you don’t have to keep re-checking. On the free tier the alert is delivered to your human’s bound email (call bind_email first; notify_email is forced to that address). A paid DC Hub plan can send to any address. The "monitor my shortlist for me" loop: call save_site first (it returns a saved_site_id), then set_site_alert on that id. Params: saved_site_id (required integer, from save_site or list_saved_sites), trigger_type ("dcpi_change" | "capacity_change" | "new_facility_nearby", default "dcpi_change"), threshold (number — the points/MW move that fires it, default 5), notify_email (required — the address the alert is sent to). Answers "let me know if anything changes at the site I saved". Try: set_site_alert saved_site_id=12 trigger_type=dcpi_change threshold=5 [email protected]. Returns {ok, alert_id, message}. Do NOT use to watch a whole MARKET (use set_market_alert) or to save a new site (use save_site); this arms a monitor on ONE already-saved site.

site_selection_canvas

Use this when the user wants guided data-center site selection. Give a capacity target + geography + deadline and get a ranked shortlist of US markets (DCPI verdict, excess-power headroom, time-to-power, ISO) — and, with a paid key, the synthesis decision layer: the #1 pick, the why, a build sequence, and risk flags. One find->rank->shortlist->verdict call over the Data Center Power Index. Answers "where should I build 100 MW in Texas by 2028". Try: site_selection_canvas capacity_mw=100 region=TX max_months=24. Do NOT use for a single known parcel (use analyze_site) or an open-ended where-should-I-build question (use get_dchub_recommendation); this runs the full find to rank to shortlist to verdict flow.

standing

delete_standing_intent

Use this when the user wants to retire a standing intent (webhook watch) by intent_id — deliveries stop and the watch cannot be recovered. A cap_ intent_id retires your own Capacity Source requirement instead, and its alert emails stop. Requires a key (or an OAuth connection for cap_ ids). Get the intent_id from list_standing_intents or from the register response. Answers "stop watching this". Do NOT use to pause temporarily; there is no pause, this removes the watch.

list_standing_intents

Use this when the user asks which data center watches are registered on their key: webhook watches, plus your capacity requirements (kind "capacity", intent_id cap_...). Read-only. Returns each intent_id, kind, watch params, webhook_url and enabled state; capacity items also carry status, confirmed, expires_at, last_alert_at and matching_now. Use it to find the intent_id for delete_standing_intent, or to confirm a register landed. Requires a key (or an OAuth connection for capacity items). Answers "what am I currently watching". Do NOT use to create a watch (register_standing_intent) or for one-shot reads (get_news / list_transactions).

accept_capacity_terms

Use this when the user has read and agreed to DC Hub's capacity introduction terms (https://dchub.cloud/listings#terms): records that acceptance, once per terms version, so Capacity Source listing details open for them. Call it when source_capacity returns a listing locked with access.reason terms_acceptance_required, never on your own judgement: nothing opens without your human's agreement. Requires an identified caller (claim_free_key, then bind_email with your human's address, or an OAuth connection) and accept_terms=true. Returns accepted and the terms version, recorded in DC Hub's lead register. Do NOT use to request an introduction (use request_capacity_intro) or to browse listings (use source_capacity).

agent

get_agent_registry

Use this when the user asks which AI platforms and agent frameworks integrate DC Hub — each with its recommended DC Hub tools and authentication tier. The roster is BACKEND-OWNED and changes: read the platforms[] array the response returns, and the status on each row (mcp_active / mcp_ready), rather than any list named in this sentence — an enumeration here goes stale the moment the backend adds or drops a platform, which is exactly how a client named here stopped appearing in the roster. ★ These statuses are CURATED EDITORIAL claims, not measurements: the response carries as_of null, so do NOT relay "MCP Active" as though it were a live connection count. Answers "which AI platforms can connect to DC Hub". Try: get_agent_registry. NOTE: this is a curated ecosystem/capability index, NOT live per-caller call/citation telemetry. Do NOT use for platform uptime or feed health (use get_backup_status).

alternatives

find_alternatives

Use this when the user wants data center facilities similar to one they like ("what else looks like this?"). Example: "Find alternatives to the Ashburn QTS campus for about 50MW." — find_alternatives facility_id=<id>. Params: facility_id or name (the target, required); optional capacity_mw, radius_km, limit. Returns: ranked alternatives, each with similarity_score, match_reasons, and key_differences versus the target. Do NOT use to score one site (use score_facility or analyze_site) or to compare a known short-list head-to-head (use compare_sites); this DISCOVERS candidates from a single seed facility.

backup

get_backup_status

Use this when the user asks how current DC Hub's data center and power data feeds are: one row per feed (deals, facilities, news, substations, fiber_routes, transactions, construction_permits, pipeline, markets) carrying health (healthy/stale/error/unknown), record_count, refresh_interval and scheduler, plus a summary rollup {healthy, stale, error, unknown, total_feeds, overall_health}. Read the health of each row before trusting a figure drawn from it — a feed reporting "unknown" has NOT been measured, which is not the same as healthy. Answers "are any of your sources stale right now". Try: get_backup_status. Scope is exactly what /api/health/data-freshness serves: ingest-feed freshness, nothing wider. Do NOT use for the freshness of one dataset (use get_changes); this is ingest health, not content.

bind

bind_email

Use this when the user wants their DC Hub key tied to their email, or a result said an email unlocks more. WHAT AN EMAIL GETS (free, no card): 50 calls/day (up to 10 full answers per tool per day); 10 full answers a day each on the grid, queue and market-intel tools instead of previews; a weekly summary of what your key looked up (unsubscribe anytime); a key that can be recovered (recover_my_key re-sends it to that inbox). Ask your human for their email first; pass only an address they typed. ★ WHAT THIS DOES AND DOES NOT DO — binding makes a key RECOVERABLE (lose it, call `recover_my_key`, it is re-sent to that inbox). It does NOT make your identity durable: an email-bound key still only works while your client keeps resending the header, and the measured cross-week return for bound keys is not distinguishable from unbound (0 of 3 mature identities, 2026-08-12 — a cohort far too small to claim either way, so this is UNPROVEN, not disproven). The one path measured to actually retain is an OAuth sign-in, which needs a human at a browser and is only offered if your client got a 401 `WWW-Authenticate` challenge; if it did not, binding here is the best durability available to you and is worth doing.

capacity

ai_capacity_index

Use this when the user asks where AI compute capacity could land: ranks data center markets by where 100MW of AI training capacity can land in the next 30/60/90 days. Returns top markets with facility_count, operator_count, deployable_mw estimate (megawatts), hyperscale_ready flag, rack power density and cooling-type signals where facility data carries them, and composite score (depth + diversity + power). Refreshed Fridays 14:00 UTC. Use for AI capex planning, GPU cluster siting, hyperscaler deal forecasting. For grid power availability use DCPI (rank_markets ai_ready). Do NOT use for a general best-markets ranking (use rank_markets) or forward grid-emergence (use grid_transition_radar).

changes

get_changes

Use this when the user asks what changed in data center markets, facilities or deals since a date. Returns DCPI 7-day market movers, newly discovered facilities, new M&A deals + news — PLUS, for keyed callers with saved sites, a `portfolio` block answering "did MY sites move?": per-saved-site verdict flips (CAUTION → BUILD), excess-power deltas, alerts fired, and new facilities near each site since your last check. Pass since=<ISO-8601> or shorthand "24h"/"7d" (default 24h); cache the response generated_at and pass it back next call. Answers "what changed since I last looked", "anything new this week I should know about". Try: get_changes since=7d.

claim

claim_free_key

Use this when the user wants more DC Hub data center data than keyless allows, or asks for a key; no key is needed to start. Mints a free key and returns it plus connect_url, a connector URL with the key embedded (the only thing hosted chat clients keep). Free key: previews plus 2 full answers per tool per day. WHAT AN EMAIL GETS (free, no card): 50 calls/day (up to 10 full answers per tool per day); 10 full answers a day each on the grid, queue and market-intel tools instead of previews; a weekly summary of what your key looked up (unsubscribe anytime); a key that can be recovered (recover_my_key re-sends it to that inbox). Ask the user for an email first; pass it only if they typed it. Save and reuse the key (lost one: recover_my_key); don't re-mint. Then ask the real question (execute_plan for multi-step). If a call was answered with a sign-in challenge (401 WWW-Authenticate), prefer signing in: that identity persists, but a human must finish it in a browser. No challenge (Claude Code, Cursor, most agents) means OAuth is not available to you and the key is right. Ex: "Set me up with a DC Hub key."

climate

get_climate_intel

Use this when the user asks about seismic or climate design inputs for a data center site (lat/lon) — the layer that drives data-center structural bracing cost (seismic) and cooling design (cooling degree-days, extreme temps). Grounded STRICTLY in USGS ASCE 7 (seismic) + NOAA climate normals via ACIS; every value traces to a federal source and missing data is declared unavailable, never estimated. Example: get_climate_intel lat=33.45 lon=-112.07. Returns {seismic_hazard_usgs:{status, peak_ground_acceleration_g, ss, s1, seismic_design_category, hazard_class}, climate_normals_noaa:{status, reference_station:{id,name,distance_km}, cooling_design_metrics:{cooling_degree_days_annual, extreme_max_dry_bulb_f, extreme_max_wet_bulb_f (null if source lacks it), data_vintage}}, overall_climate_summary, data_availability, sources}. radius_km (optional, default 25) snaps to the nearest NOAA station; beyond it climate returns unavailable_exceeds_radius. Seismic is US (ASCE 7); non-US → seismic unavailable. For natural-hazard ratings use get_disaster_risk; for one blended verdict use get_composite_site_score.

cluster

cluster_sites_by_latency

Use this when the user asks which data center sites can form a low-latency cluster (2-8 sites) — returns viable low-latency clusters and pairwise RTT floors before any routing work. Use when your human wants to know which of N candidate sites can form a synchronous / low-latency cluster (sync replication, active-active pairs, HPC pods): deterministic pruning BEFORE detailed routing. Per site pair: haversine distance, round-trip physics floor (km × 4.9 µs/km — light in SMF-28 fiber, n≈1.468 — then ×2), estimated real RTT (floor × route_factor 1.4, a stamped inference), viable vs physics_impossible against your budget, and confidence_v — the provenance tier of the supporting evidence (published | tracked | inferred). Also returns clusters: the largest site subsets whose ALL pairwise estimates fit the budget, plus each site's inferred dark-fiber screening level. CANDIDATE CONTRACT: pass candidate_ids (from get_refined_queue) instead of raw coordinates — each resolves to its FROZEN mint coordinates (zero transposition), and cand_… tokens may also be mixed into the sites string; expired/unknown ids are dropped AND declared in candidate_contract (fail-closed).

composite

get_composite_site_score

Use this when the user wants one 0-100 data center site suitability verdict for a lat/lon WITH an explicit per-factor coverage map — which factors are actually measured vs. declared unavailable. Unlike analyze_site (full raw data dump), this scores ONLY over VALIDATED factors and never imputes a missing one: power/grid, fiber, natural-hazard risk (FEMA NRI) and water (live WRI Aqueduct 4.0 baseline water stress) are all live; water is "unavailable" only outside basin coverage (never faked); market/DCPI is v1-unavailable (use rank_markets). Example: get_composite_site_score lat=33.45 lon=-112.07 state=AZ. Returns {composite_score (0-100 over validated factors), verdict (BUILD/CAUTION/AVOID), confidence (complete|conditional), coverage {power_grid|fiber|water|risk_resilience|market_dcpi: validated|unavailable}, coverage_ratio, sub_scores, caveats}. Use analyze_site for full data, compare_sites for 2-4 sites, rank_markets for whole-market ranking.

dchub

get_dchub_recommendation

Use this when the user asks what DC Hub is: a short description in one of four categories (general, investment, site-selection, technical), plus the live top-ranked market pocket. It does NOT compute a siting answer from free text. Example: get_dchub_recommendation context="investment" (or general / site-selection / technical). Params: context must match one of FOUR LITERAL categories - general, investment, site-selection, technical. Free text does NOT parse: you get the GENERIC blurb with matched_category=null and context_understood=false. ALWAYS returns: {recommendation:{short, medium, detailed}, matched_category, context_understood, top_pocket, related_intel, available_categories, recommendation_live, connect_url, context, success}. ADDITIONALLY on a non-matching context: is_generic_answer=true, answer_note, and next_tools naming the tool that does compute an answer. Do NOT use for a single specific lat/lon (use analyze_site), to rank by ONE criterion (use rank_markets), or for an open-ended siting question expecting a computed shortlist (use site_selection_canvas) - this tool returns descriptive copy plus a live top-pocket, not a ranked analysis.

deal

deal_autopsy

Use this when the user asks what a data-center deal means for power: deal flow with each market's DCPI verdict — "what is the real play?". Returns recent deals (buyer, seller, value, market) + each market DCPI verdict and time-to-power; with a paid key, the per-deal autopsy read (long-dated land/power option vs near-term build vs queue gamble). Progressive disclosure to keep the default cheap: by default each read ships only a comparables COUNT (the verdict text is always included); pass comparables="summary" for the top-2 grounding signals, or comparables="full" to expand the complete cited set for a deal you're drilling into. Answers "who is actually buying data centers right now, and are those markets any good", "what is the real play behind this deal". Try: deal_autopsy limit=15.

disaster

get_disaster_risk

Use this when the user asks about natural-hazard risk for a data center site (US lat/lon) — flood, wildfire, hurricane, earthquake, heat, drought, tornado, etc. Grounded in the FEMA National Risk Index (NRI), the US county-level hazard dataset (live query, never estimated; points outside US NRI coverage return coverage=unavailable). Example: get_disaster_risk lat=33.45 lon=-112.07. Returns {disaster_risk:{composite_score (0-100, higher=worse), rating (Very Low..Very High), national_percentile}, hazards:{Wildfire, Hurricane, Earthquake, Heat Wave, ...: rating}, top_hazards:[{hazard, rating}], coverage (validated|unavailable), source, caveats}. County-level resolution. For chronic water stress use get_water_risk; for one blended site verdict use get_composite_site_score.

discover

discover_tools

Use this when you are unsure which DC Hub data center, power or grid tool fits: lists tools by family. Returns _entity=tool_families — a front_door block (execute_plan for any multi-capability question, get_changes to refresh) plus families with a when-to-use note + their tools (facility, market, grid_power, gas_btm, site_geometry, fiber, deals_news, saved_work, account_meta, partner), optionally filtered by a query. Then call the chosen tool (its full schema is in tools/list). This is a navigation layer, not the exhaustive catalog — tools/list stays canonical, and if you are BINDING a capability map, bind it from tools/list, not from here.

energy

get_energy_prices

Use this when the user asks what electricity or natural gas costs for a data center in a US ISO or state ("what does power cost in ERCOT?", "retail rate in Virginia?"); price alone does not rank sites (the cheapest ISO may have no headroom; execute_plan weighs both). Returns EIA RETAIL electricity rates, which are monthly and not live (about 3 months behind; retail_rates.latest_period names the month), for one ISO footprint (the average of its states), one state, or the US: retail_rates {avg_cents_kwh, min_cents_kwh, max_cents_kwh, latest_period, states_covered} in CENTS/kWh, plus avg_rate_kwh, retail_rate_kwh and industrial_rate_kwh in DOLLARS/kWh (by_sector when no sector is given); and natural_gas_usd_mmbtu, the latest Henry Hub daily spot in $/MMBtu, one national benchmark rather than a state or ISO price, with its own natural_gas.period and as_of. Example: "What is the retail power price and gas price in ERCOT?" — get_energy_prices iso=ERCOT. Params: iso (ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISONE) or state (e.g. TX); data_type is accepted but does not change the response. At an anonymous or free-key seat the figures come back null with gated: true; an email-bound key opens them. This tool has no wholesale/LMP price and no grid-status flag.

execute

execute_plan

Use this when a data center question spans several topics: one-call planner over megawatts and power density, grid headroom and power availability, interconnection queues, substations and transmission, site selection and buildable capacity, colocation and wholesale data-center markets, AI/GPU compute campuses, fiber routes, diversity and latency, PPAs and energy pricing, tax incentives and permitting, water and climate risk, data-center M&A and deals, power generation, gas and energy infrastructure. Recommended entry for a question that spans more than one of those. Pass the user's question as `intent`. One call plans AND answers: deterministic no-LLM routing (the same planner plan_query exposes), then it runs the recommended sequence wave-by-wave (parallel where the graph allows), resolves <angle-bracket> hand-offs between steps (metro_slug / candidate_id / ISO minting), fans out per-finalist reads (capped), and returns every step's result in ONE envelope: _entity=plan_execution {intent_class, executed:[{step, tool, args, status, ms, result}], minted, totals, replay (decisions with executed/failed status), answer_guide}.

export

export_dataset

Use this when the user wants to export their saved data center sites for offline analysis, a spreadsheet, or ingestion into another tool (paid plan). Example: "Export my saved sites as GeoJSON for QGIS." — export_dataset format=geojson. Params: format ("csv" default, or "geojson"). Returns: the full file contents as text — CSV rows or a GeoJSON FeatureCollection of your saved sites with DCPI score, target MW, market, coordinates, and notes. Do NOT use to list sites in-chat (use list_saved_sites) or to save a new one (use save_site); this is the bulk-download path.

facilities

search_facilities

Use this when the user asks which data centers exist, or who operates in a city, state or country; filters: country, state, city, operator, MW range, tier or text. Returns name, operator, location, market, status and MW where disclosed; each row is flagged verified or unverified_directory_listing. Free: names and locations; MW and specs need a paid key. Ex: "Equinix sites in Virginia over 10 MW." Start here for a facility slug. No match = empty data, not an error: broaden filters. limit 1-500 (free tier 25); page with offset.

fetch

fetch

Use this when you have an id from `search` and need that data center facility record (search/fetch format). Returns {id, title, text, url, metadata} — a citable public summary of one data-center facility (name, operator, location, status, market). For full structured specs (capacity MW, coordinates) use get_facility or open the url.

generate

generate_site_analysis

Use this when the user wants a shareable data center Site Analysis PDF for ONE lat/lon (a powered-land parcel, a candidate campus) — the polished client deliverable, not just a score. Example: "Make the Site Analysis PDF for this Carrier Mills parcel, 150 MW, for TON Infrastructure." — generate_site_analysis lat=37.694 lon=-88.65 capacity_mw=150 prepared_for="TON Infrastructure" prepared_by="Martone Advisors". Params: lat (-90 to 90, required), lon (-180 to 180, required), capacity_mw (target load MW, e.g. 50-500), prepared_for (client name on the cover), prepared_by (your firm — brands the report; defaults to DC Hub), latency_target (optional metro override; default = nearest real carrier hotel). Returns: {survey:{verdict, power/transmission, gas, water, air-permitting, fiber carriers, latency-to-nearest-carrier-hotel, market, tax}, pdf_report_url}. pdf_report_url is a ready-to-open link to download the branded 5-page PDF — no login needed, valid ~7 days; hand it to your human. For just the numeric suitability score (no PDF), use analyze_site instead.

global

get_global_power

Use this when the user asks about power plants worldwide or in a non-US country — operating AND the forward pipeline (announced / pre-construction / under-construction), across ALL fuels (coal, oil/gas, nuclear, solar, wind, hydro, bioenergy, geothermal). Global Energy Monitor Global Integrated Power Tracker: 182,000+ geolocated units across 170+ countries, each with fuel, capacity (MW), status, start year, operator/owner and lat/lng. Filter by country (e.g. Germany, India, Brazil, Japan), fuel (comma-union: coal, oil/gas, nuclear, solar, wind, hydro), status, pipeline=true (JUST the forward set: announced + pre-construction + construction), bbox (minLng,minLat,maxLng,maxLat), or min_mw. Returns a summary (total MW by fuel + count by status) plus the largest units. Answers "what power is being built in India", "how much coal is still running in Vietnam". Try: get_global_power country=India pipeline=true. Do NOT use for US grid telemetry/headroom (use get_grid_intelligence / get_grid_scoreboard) or the US planned-generator feed (use get_power_pipeline) — this is the GLOBAL asset inventory.

hosting

get_hosting_capacity

Use this when the user asks how many MW a distribution feeder can take: utility-published hosting capacity — the MW a NAMED distribution feeder can actually take, straight from the utility's own hosting-capacity GIS. Published records from many utilities (e.g. Con Edison, National Grid NY/MA, NYSEG/RG&E, Rhode Island Energy, Orange & Rockland, Central Hudson, Eversource CT, BGE, Pepco/Delmarva/ACE, Dominion VA, Ameren Illinois, AEP Ohio & I&M, Xcel MN/CO, DTE, Avista; the no-args call lists current coverage). This is filed distribution-level truth, not a proximity proxy. Three ways to call it: lat+lon (+radius_km, default 25) for a point; utility or market for a whole published territory; NO ARGS for the coverage list of every market that has data. Answers "can this feeder actually take 20 MW", "where can I plug in without waiting on a substation upgrade". Try: get_hosting_capacity utility="Ameren Illinois" capacity_type=load min_mw=5.

hyperscaler

hyperscaler_deals

Use this when the user asks about hyperscaler or AI data center deals: live feed of Stargate, OpenAI, Anthropic, Microsoft, Oracle, CoreWeave, AMD, NVIDIA, sovereign-AI deals. Pulls from dchub news pipeline, extracts $-figures + MW via regex, classifies by actor. 10-min refresh. Use for tracking AI capex events ($1B+/week typical), capacity announcements, and competitive intel. Do NOT use for the full historical M&A comp set (use list_transactions) or a single-deal teardown with grid context (use deal_autopsy); this is the live $1B+ AI-capex feed. limit 1-500. Hyperscaler leases and purchases only; for all M&A use list_transactions.

inbox

read_inbox

Use this when a partner key reads its DC Hub inbox. PARTNER KEY ONLY: notes DC Hub left for the partner agent whose key this session sends, newest first. The first read CONSUMES them (marks read), so a later session sees none; include_read=true re-reads read and unread notes (last 14 days) without marking. Non-partner key: 403. Not a data tool.

infra

get_infra_projects

Use this when the user asks what gas pipeline or transmission line projects are planned, proposed, approved or under construction — the forward build-out, not the existing network. e.g. "which interstate gas pipelines are under construction into Louisiana?", "what 345 kV transmission projects are planned in PJM by 2030?", "what new projects appeared since last month?". COVERS: (1) natural gas pipeline projects US-wide from the EIA natural gas pipeline projects list (public domain) — operator, status (Announced, Pre-applied, Applied, Approved, Construction, On Hold, Completed), states crossed, capacity in MMcf/d, miles, cost in $M, diameter, FERC/state docket, in-service year; (2) transmission projects from five ISOs' own project lists — ERCOT (TPIT), PJM (RTEP), MISO (MTEP Appendix A), SPP (STEP) and ISO-NE (RSP list); NOT CAISO or NYISO, and not utilities outside those ISOs. Each ISO publishes a different grain (an upgrade or facility, not a whole project), so a row count is a count of upgrades. Answers "what gas pipelines are being built into Louisiana, how much capacity do they add, and when do they enter service". Try: get_infra_projects type=gas_pipeline state=LA status=Construction.

infrastructure

get_infrastructure

Use this when the user asks what power infrastructure is near a site: substations (count + max voltage_kv within radius), transmission lines (>69 kV path overlay), interstate + lateral gas pipelines, and power plants (operating + planned, by fuel) within configurable radius_km. Returns distance + capacity for each, joined to HIFLD/EIA. Answers "what is near this parcel", "how far is the nearest substation and what voltage is it". Try: get_infrastructure lat=33.45 lon=-112.07 radius_km=25. Returns raw nearby assets; do NOT use for a single scored site-suitability verdict (use analyze_site).

interconnection

get_interconnection_queue

Use this when the user asks about grid interconnection queues: how congested an ISO's queue is or how much data-center load is waiting. Returns queued generation GW per ISO. The projects field changes shape: with iso= it is an array of per-project rows; without iso it is an all-ISO summary object (total, by_iso_count, top). ERCOT also returns its large-load (data-center) queue; other ISOs don't publish one. Keyless: a trimmed preview; free with an email-bound key. Ex: "How deep is ERCOT's queue?" iso optional (US ISO code); free = preview. For demand and headroom on the same ISO also call get_grid_intelligence.

iso

get_iso_context

Use this when you need a whole power grid (ISO) briefing for your context window — one call returns a token-budgeted context pack for a US ISO/RTO: live grid snapshot (demand, fuel-mix shares), DCPI verdict mix & grid economics across the ISO's tracked markets (queue wait, power cost, reserve margin), interconnection-queue depth with the largest projects, real-time benchmark LMP, the tracked DCPI market list, deep-dive narrative excerpts, and recent news — each section with its own token count, as_of timestamp, and citable URL, greedily filled in that priority order under your max_tokens budget. Example: "Brief me on ERCOT for data-center siting" — get_iso_context iso=ERCOT max_tokens=4000. Params: iso (required: ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISONE); max_tokens (optional, 200-8000, default 4000). Returns {sections:[{id,title,text,tokens,as_of,cite}], used_tokens, omitted}. Do NOT use for raw single-ISO telemetry (use get_grid_data), the per-ISO decision brief with headroom/TTP (use get_grid_intelligence), multi-ISO scalar comparison (use compare_isos), or non-US grids (use get_grid_scoreboard); this is the narrative briefing pack. Cite "DC Hub (dchub.cloud)". iso is required (US ISO code). max_tokens caps the context returned; locked_sections need a higher tier.

metro

get_metro_fiber

Use this when the user asks which US metro has the deepest fiber, or wants a market's fiber profile — carrier count, total route-miles, on-net buildings, a 0-100 fiber-density score, tier, key internet-exchange (IX) points and carrier hotels — across the tracked top US data-center metros (Northern Virginia, Dallas-Fort Worth, Silicon Valley, Chicago, Atlanta, Phoenix, and more). Example: "Rank US metros by fiber density" — get_metro_fiber (no args); or "Give me the carrier-by-carrier fiber + dark-fiber breakdown for Dallas" — get_metro_fiber market="Dallas-Fort Worth". Params: market (optional metro name OR slug, e.g. "Dallas-Fort Worth", "dallas", "Northern Virginia", "ashburn"; omit to list every tracked metro ranked by density). Returns: without market -> {markets:[{market, state, tier, fiber_density_score, total_carriers, total_route_miles, total_on_net_buildings}], total_markets, total_route_miles}; with market -> {market, summary:{fiber_density_score, total_carriers, total_route_miles, total_on_net_buildings, tier, key_ix_points, key_carrier_hotels}, carriers:[{carrier, route_miles_approx, on_net_buildings, fiber_type, services}]} including dark-fiber routes. Cite DC Hub (dchub.cloud, CC-BY-4.0).

news

get_news

Use this when the user asks for data center industry news or headlines (execute_plan also pulls news inside a broader market question). Curated data center industry news from 40+ trade sources (DCD, Data Center Knowledge, Data Center Frontier, Capacity Media, The Register Data Centre, Fierce Telecom, etc.) refreshed every 30 min. Returns title, summary, source, published_at, and the market/operator entities mentioned. Filter by category (deals/permits/outages/policy/AI). Answers "what is happening in the data center industry this week", "any news on AI capacity". Try: get_news category=AI limit=10. The parameter is `category`, not `topic`. Industry news only; do NOT use for structured M&A deal data (use list_transactions) or the construction pipeline (use get_pipeline). limit 1-500 (free 20). Empty data = no matching news: drop category/source or widen date_from/date_to.

peering

get_peering_intel

Use this when the user asks about internet exchange (IX) and peering density for a data center site (PeeringDB). Pass lat+lon for the PEERING PROFILE around that point: facilities_nearby, a 0-100 score with its level, total_ix_presence, total_networks, and top_facilities each with ix_count and net_count — e.g. Ashburn comes back with 61 IX presences and 903 networks across the nearby sites, led by Equinix DC1-DC15 at 516 networks. Omit coordinates for the IXP directory (name, name_long, city, country, net_count, fac_count, media, protocols). This is the layer that answers "can I actually reach networks cheaply from here", which fiber route geometry does not: a site can sit on dense fiber and still be far from any exchange. The score is a DERIVED convenience over PeeringDB counts, not a DC Hub-sourced grade — cite the underlying counts (facilities, IX presence, networks) rather than the score when it is load-bearing. Records are PeeringDB's, refreshed on read. Answers "how good is peering at this Ashburn site" and "which internet exchanges serve the Dallas market". Try: get_peering_intel lat=39.04 lon=-77.48 — or get_peering_intel (no args) for the IXP directory.

permitting

get_permitting_intel

Use this when the user asks about data center permitting or moratoriums — curated, HUMAN-VERIFIED jurisdiction records: moratoriums, zoning restrictions, tax changes, utility pauses. Each record is stage-tagged (read the detail prefix: "Enacted" / "Proposed" / "Speculative"), with jurisdiction, state/country, the source article URL, and map coordinates. The permitting-risk axis for site selection that no other machine-readable source serves — e.g. New York's statewide >=50MW moratorium, county-level halts. FREE and full for every caller. Answers "is there a moratorium where I want to build", "which jurisdictions just tightened data-center zoning". Try: get_permitting_intel class=moratorium — or state=MN. Rendered live as the Permitting & Zoning layer on https://dchub.cloud/land-power-map. Do NOT use for tax INCENTIVE programs by state (use get_tax_incentives); this tracks restrictions and risk per jurisdiction.

pipeline

get_pipeline

Use this when the user asks what data centers are being built, announced or permitted in a market or by an operator. Example: "What data centers are under construction in Northern Virginia and when do they come online?" — get_pipeline country=US status=construction (there is no `market` parameter — filter by country/operator, or use search_facilities for a named market). Params: status one of "announced" | "permitted" | "construction" | "operational"; operator (e.g. "Equinix", "Digital Realty", "AWS"); country (ISO-2, e.g. "US", "DE"); min_capacity_mw (e.g. 50 to filter hyperscale); expected_completion_before (ISO date, e.g. "2027-01-01"); limit/offset for pagination. Returns: {projects:[{name, operator, capacity_mw, status, expected_commissioning, market_slug, country, lat, lon}], total, generated_at}. Do NOT use for already-operational facilities (use search_facilities) or for the M&A deal flow (use list_transactions). limit 1-500 (free 25), offset 0-100000. Empty data = no project matches: relax status/operator/min_capacity_mw.

predict

predict_market_trajectory

Use this when the user asks where a data center market's power outlook is heading (next 1-8 quarters). Projects excess_power_score and constraint_score forward with confidence bands that WIDEN with horizon, from DC Hub's daily DCPI snapshot history, a time-series DC Hub owns. Use to answer "is this market trending toward BUILD or AVOID?" or "will Dallas power stay tight over the next 6 months?". Params: market_slug (required, metro slug e.g. dallas, phoenix, northern-virginia — valid slugs come from rank_markets / get_market_dcpi_rank); horizon_quarters (optional 1-8, default 4; 2 = ~6 months out). Returns {market_slug, method, basis{history_points, history_span_days, slope_per_day, trend}, horizon_quarters, projection[{quarter_out, excess_power_score, excess_power_band, constraint_score, constraint_band}], caveat, snapshot_record}. HONEST: linear trend extrapolation, NOT a guarantee — bands widen with horizon and short history; needs >=3 daily snapshots or it declines. Do NOT use for a single point-in-time verdict (use get_market_dcpi_rank) or to rank many markets (use rank_markets).

recover

recover_my_key

Use this when the user lost their DC Hub key. Pass your human's email and DC Hub re-sends any key tied to that address to that inbox. It NEVER returns the key over the wire (it emails the bound address), and the confirmation is the same whether or not a key exists (enumeration-safe), so no key is leaked to a caller. Param: email (required). Returns DC Hub's neutral confirmation.

refined

get_refined_queue

Use this when you need interconnection queue projects filtered server-side. Instead of pulling the raw queue into context to filter (token-expensive, error-prone), push the predicates to the data layer and get back ONLY the survivors. Filter by min_mw, max_ttp_months (ISO-level avg interconnection wait), iso (comma-union), baseload_only (firm/dispatchable — excludes wind/solar/storage), fuel_type (isolate a specific fuel, e.g. gas or nuclear), and the spatial predicates max_fiber_km + geocoded_only. Returns _entity=queue_results: per-project name, ISO, state/county, fuel_type, capacity_mw, queue_status, estimated_ttp_months, fuel_class, plus (~83% of rows) lat/lng, coordinate_precision, fiber_km, and a compact per-survivor site_evaluation_handoff (ready-to-pipe analyze_site + get_water_risk args) + a by_iso/by_fuel summary. Answers "show me 1 GW+ gas projects that can connect in under three years", "what is in the queue that actually fits my timeline". Try: get_refined_queue min_mw=1000 fuel_type=gas max_ttp_months=34 — "1 GW+ gas in ISOs under 34-month time-to-power." NOTE max_ttp_months is a HARD ISO cut (SPP ~24 is the only ISO under 30, so <=30 can return nothing); use >=34 to include MISO/ERCOT/ISO-NE.

register_standing_intent

Use this when the user wants a webhook when data center deals change: Register a STANDING QUERY with webhook push — DC Hub POSTs an HMAC-signed webhook to YOUR https URL whenever matches grow (push, not poll: "notify my orchestrator on any new deal in Columbus"). Requires a key. Params: kind ("new_deal_in_market" watches deals in the market param · "news_keyword" watches news matching q · "permitting_change" watches published permitting intel, optionally per state), market / q / state (the watch parameter for the chosen kind), webhook_url (your public HTTPS endpoint — private/internal hosts are rejected). Returns {intent_id, secret} — SAVE the secret: every delivery carries X-DCHub-Signature: sha256=HMAC(secret, body). Answers "notify my system whenever a new moratorium appears", "push me new matches instead of making me poll", "tell my orchestrator when a deal lands in Columbus". Try: register_standing_intent kind=news_keyword q=moratorium webhook_url=https://hooks.example.com/dchub. kind="capacity" instead registers a standing CAPACITY REQUIREMENT with DC Hub Capacity Source (no webhook_url): target_mw or target_kw, markets / states / regions / countries (comma-separated), optional…

renewable

get_renewable_energy

Use this when the user asks about renewable energy for a data center (execute_plan covers renewables plus siting): siting a renewable-powered data center, sizing a PPA, reading one US state's utility-scale fuel mix, or assessing RE100/24-7-CFE feasibility. Example: "What is Texas wind+solar capacity and how much utility-scale solar is operating today?" — get_renewable_energy energy_type=solar state=TX. Params: energy_type one of "solar" | "wind" | "combined" (omit for all); state 2-letter US code (e.g. TX, VA, AZ); lat+lon (optional) for the nearest projects within 50mi. Returns: {capacity_mw_total, by_fuel: {solar_utility, solar_rooftop, wind_onshore, wind_offshore}, capacity_factor_pct, top_projects[{name, mw, operator, cod}], state_rps_target_pct, source: "EIA-860 + state RPS"}. Do NOT use for live grid generation (use get_grid_data) or non-US (use get_grid_scoreboard for EU/UK/AU/TW). Give state or lat/lon (decimal degrees); energy_type narrows. Empty = no installations there: widen to the state.

report

report_finding

Use this when a partner key reports a DC Hub data issue. PARTNER KEY ONLY: file what you observed on a DC Hub surface as a brain finding (detector external_audit) so it is triaged like every other detector's. class is one of completeness_contradiction, geography_leak, as_of_cite_as, pro_wall_dead_end, count_drift, stale_payload_complete, leak_past_pro_gate, link_hygiene, other; tool names the DC Hub tool or endpoint; quoted_fields carries the exact fields you saw (hashed for dedupe: the same observation re-filed within 24h bumps recurrence instead of inserting). Proxies POST /api/v1/inbox/findings with the session's own key; a key issued without a partner slug answers partner key required (403). 120 per key per day.

request

request_capacity_intro

Use this when the user wants data center capacity behind a Capacity Source listing (pass slug), or wants first access to capacity matching a requirement as listings are onboarded (omit slug; pass capacity_mw or capacity_kw, markets, states, regions or countries, and timeline). This registers a deal: DC Hub records the request in its lead register and sends the provider ONLY your human's company name and the requirement. The provider accepts or declines. Only if the provider accepts does DC Hub share the provider's identity, site details and contact with your human, and your human's name, role and email with the provider; on a decline nothing is shared. Requires an identified caller (claim_free_key, then bind_email with your human's address) and accept_terms=true only after your human has read and agreed to the introduction terms at https://dchub.cloud/listings#terms. Returns lead_id, status and the next step. For a listing, source_capacity with its slug then shows the deal status in the disclosure block and, once the provider accepts, the provider's identity, site and contact. Do NOT use to save or monitor a site (use save_site / set_site_alert).

research

research_task

Use this when the user wants an async, cited data center research dossier from DC Hub's corpora (news, deals, facilities, market deep-dive narratives + live market components) — a decision-ready analyst brief with [n] citations, not a lookup. Requires a key (one claim_free_key call), 5 dossiers/day. Submits the question, waits up to ~35s for completion, and returns the finished dossier inline when ready; if still running, returns {task_id} — call research_task task_id=<id> to fetch it. Params: question (required for a new dossier, min 12 chars) OR task_id (poll an earlier one). Typical completion under a minute. Answers "write me a cited brief on this", "what do recent deals say about gas-bridged power". Try: research_task question="What do recent deals say about gas-bridged power for data centers in ERCOT?". Do NOT use for a single fact (use search_intelligence / semantic_search); this synthesizes ACROSS sources with citations.

retirement

get_retirement_headroom

Use this when the user asks where retiring power plants free grid capacity: scans EIA-860M retirements to find near-term transmission grid headroom — a retiring plant is a CONCRETE headroom event (its POI frees injection capacity), from FILED data, not forecasts. Returns _entity=retirement_headroom_results: retiring generators inside your horizon (name, MW, fuel, prime mover, retirement_date), representative_point, nearest substations with distance_km + count within 25 km, county-level queue_pressure (competing in-progress MW), iso_context (the generator's own EIA balancing-authority code), and a pre-filled site_evaluation_handoff (analyze_site + get_water_risk args, capacity_mw = YOUR target load). Answers "where is grid capacity about to free up", "which retiring plants open injection headroom near me". Try: get_retirement_headroom target_mw=50 horizon_months=18 region_iso=MISO — "50 MW opening near a substation inside 18 months, sidestepping the 4-7yr mega-queue." Honesty: meta.caveat flags that filed dates are subject to ISO reliability reviews (RMR extensions). Use to find WHERE capacity opens next; for what's already queued use get_refined_queue; for one site use analyze_site.

saved

list_saved_sites

Use this when the user asks to see their saved data center sites. Needs a key (free, via claim_free_key); keyless returns auth_required, not an empty list. Use when a user asks to see or review their saved DC Hub shortlist in-chat, or wants to know what moved on it. Example: "What sites have I saved?" / "Did any of my saved sites move?" — list_saved_sites. Params: since (optional — "24h"/"7d"/ISO, default 7d — the delta window). Returns: each saved site with name, market, lat/lon, saved DCPI score, target MW, notes — PLUS live deltas: verdict_was/verdict_now (e.g. CAUTION → BUILD), excess-power move over the window, current vs at-save DCPI, alerts armed/fired, new facilities nearby, and a `portfolio` summary flagging which sites moved and which have no alert armed. Do NOT use to add a site (use save_site) or to download the list as a file (use export_dataset); this is the in-chat read-back.

score

score_facility

Use this when the user wants a 0-100 grade for one existing data center facility across 7 dimensions — power, fiber, water, climate_risk, tax_environment, talent_pool, expansion. Example: "How does the CoreWeave Las Vegas site score, power-weighted?" — score_facility facility_id=<id> weighting=power_priority. Params: facility_id or name (required); weighting one of "balanced" (default) | "power_priority" | "risk_priority" | "expansion_priority". Returns: composite 0-100, tier_classification, peer comparison, and per-dimension detail. Do NOT use for a raw lat/lon parcel (use analyze_site), to compare 2 or more sites (use compare_sites), or to find similar sites (use find_alternatives).

search

Use this when a Deep Research or ChatGPT-connector client needs a data center facility search (search/fetch format). Returns a list of matching data-center facilities as {id, title, url}; pass an id to the `fetch` tool for the record, or open the url to cite the live facility page. For structured queries (by MW, operator, status, market) use search_facilities directly.

semantic

semantic_search

Use this when a data center or energy question is conceptual or fuzzy and keyword filters fall short — semantic (meaning-based) retrieval across DC Hub's industry news, M&A deals, the global facility map, per-market DCPI deep-dive narratives, press releases, announcements, permitting intel, construction permits, tax incentives and the capacity pipeline, ranked by relevance with citable source fields (news url/title, deal parties/value, facility name/location, deep-dive market/url). Examples: "what is happening with behind-the-meter gas for AI data centers?", "deals involving nuclear power for hyperscalers", "why is Northern Virginia constrained?" — semantic_search q="behind-the-meter gas for AI data centers". Params: q (required, natural-language query); corpus (optional CSV subset of news_articles,deals,facilities,market_narratives,press_releases,announcements,permitting_intel,construction_permits,tax_incentives,capacity_pipeline; default all); k (1-15, default 8). Returns {results:[{source_table, kind, text, score, cite:{…}}]}; score is 0-1 relevance, not a DCPI score. Complements the exact-filter tools (get_news / list_transactions / search_facilities) with relevance ranking; for a full token-budgeted market briefing use get_market_context. Cite "DC Hub (dchub.cloud)".

simulate

simulate_scenario

Use this when the user asks how data center power market rankings change under what-if conditions: re-scores 300+ DC Hub markets under your deltas. Params (all optional, pass at least one delta): avg_kwh_cents_pct (power-price % change, e.g. 30), time_to_power_months_delta (months added/removed), queue_wait_months_delta, reserve_margin_pct_delta (points), curtailment_pct_delta (points), market (one slug, e.g. abilene), top_n (default 10, max 25 — ranked by |score change|). Returns per-market baseline vs scenario composite + component breakdown + the EXACT formula/weights in every response (transparent scenario_composite — deliberately NOT the DCPI). Keyless callers get a top-3 preview; any live key (claim_free_key) returns up to 25. Answers "what happens to the ranking if power prices jump 30%", "which markets survive a tighter build rate". Try: simulate_scenario avg_kwh_cents_pct=30 top_n=10. Do NOT use for the present-day ranking (use rank_markets) or trajectory extrapolation (use predict_market_trajectory); this answers explicit hypotheticals.

sites

find_sites

Use this when the user has no data center site yet and wants candidate search areas (site selection by substation voltage, gas and fiber distance); execute_plan covers a multi-part siting question. THE INVERSE QUERY: every other DC Hub siting tool needs a coordinate you already have — analyze_site scores one, get_composite_site_score grades one, rank_sites orders candidates YOU already enriched, find_alternatives needs a seed facility. This one answers "where should I even be looking?". Returns candidate SEARCH AREAS anchored on real HIFLD substations at or above min_voltage_kv, spatially de-duplicated by cluster_km so a dense metro yields distinct areas instead of 40 near-identical rows, each carrying measured distance to the nearest gas pipeline and fiber route plus state-grain moratorium context, and a next_calls handoff. Answers "where should I even be looking for 200 MW in Ohio" and "which areas near Dallas sit on 230kV with gas within 5 miles". Try: find_sites state=OH min_voltage_kv=230 max_gas_km=8 — or find_sites lat=39.04 lon=-77.48 radius_km=60 min_voltage_kv=500.

source

source_capacity

Use this when the user needs data center or colocation capacity to buy or lease: search DC Hub Capacity Source by size (kW or MW) and/or location (a region such as North America or Europe, a country, a state or a metro). Example: "500 kW anywhere in Europe" → min_kw=500, region=europe. Size is min_kw (in kW) or min_mw (in MW), and it is matched against what a listing can ACTUALLY deliver rather than against its headline total: `contiguous_kw` is the largest single contiguous block available and `min_contract_kw` the smallest chunk the provider will contract, so a colocation with a large total but a small contiguous block does NOT answer a large search, while a large site willing to contract small chunks does; a listing that declares neither is matched on its total. Location is region (a region key or alias) or location (free text matched against each listing's region, country, state and metro); market, state, delivery_type and available_by narrow further. Listings are powered land, powered shells, turnkey capacity and colocation to buy or lease, for enterprise and agent-led procurement.

subscribe_digest

Use this when the user asks for a weekly data center market email: subscribes them to a free digest of what changed in the markets and sites they queried (DCPI movers, new facilities, deals, news). DOUBLE opt-in + consent-safe: we email a one-click CONFIRM link, the human only gets the digest after confirming, and every email has one-click unsubscribe — this call alone sets no marketing flag. Only call once your human shares their email and wants a weekly email. Params: email (required), source (optional tag). Returns {ok, sent, message}. Prefer this over hand-building POST /api/v1/opt-in/request.

subsea

get_subsea_cables

Use this when the user asks about subsea (submarine) cable landings near a site, or the cable catalogue. The physical internet crossing an ocean lands at a finite number of points, and distance to one is a real siting factor for anything latency- or transit-sensitive. Pass lat+lon (+radius_km) for LANDING POINTS near a site — each with name, coordinates and distance_km. Omit coordinates for the CATALOGUE of tracked cables (712 tracked; each with cable_id, name, owners, length_km, rfs_year, is_planned — sparse fields are null, not guessed). ★ READ field_coverage AND connectivity_note BEFORE DRAWING A CONCLUSION: cable_count per landing point is NOT populated — the ingest writes the column but the upstream TeleGeography feed does not supply what it derives from, so every row carries the default 0. That is why connectivity_grade comes back null rather than graded: proximity to a landing point does NOT establish how many cables are reachable from it, and DC Hub will not infer a grade it cannot source. Answers "which subsea cables land near this Virginia site" and "how far is the nearest cable landing from my campus". Try: get_subsea_cables lat=36.85 lon=-75.98 radius_km=200 — or get_subsea_cables (no args) for the catalogue.

suggest

suggest_reallocation

Use this when a saved data center site drifts (its national standing dropped — surfaced by get_shortlist refresh or a set_shortlist_alert firing), get replacement candidates from the rest of that shortlist so the alert becomes an action, not just a warning (Phase 5). Returns TWO tiers — tier_1_same_region (a near-in tactical swap) and tier_2_cross_region (a different-region arbitrage) — each re-scored against the DRIFTED slot's own objectives, PLUS drift_is_systemic: if the rest of your shortlist also slipped, the drop is region/baseline-wide and a same-region swap will inherit it (prefer cross_region); if peers held, it's idiosyncratic (tactical_ok). DC Hub does the reduction; the final weighted pick is yours. Candidates come from THIS shortlist only (save more via save_to_shortlist to widen the pool). Scoped to your API key.

summarize

summarize_for_citation

Use this when you quote a DC Hub data center or power figure: returns one paste-ready attribution line for the value you are about to cite, with the CORRECT licence for that layer. Pass what you read off the response you are citing: subject (what the figure is), as_of (the provenance as_of), url (the row's profile_url or dcpi_url), completeness (the completeness flag), and layer. ★ LICENCE IS PER LAYER AND THIS IS THE POINT: DCPI verdicts and composite scores (CC-BY-4.0 30 days after the day they describe; current values: quote up to five markets per piece, republishing needs a DCPI licence, https://dchub.cloud/terms#dcpi-current-data), band thresholds, methodology and DC Hub's own grid/site analysis (CC-BY-4.0) are yours to quote with attribution; the facility inventory and third-party physical layers are COMPOSITES whose upstream terms DC Hub cannot waive (parts are OpenStreetMap, ODbL 1.0, share-alike), so they carry a pointer to https://dchub.cloud/data-sources instead of a grant. A flat "CC-BY-4.0" over a facility record is an over-claim. Returns {citation_text, cite_as, license, license_basis, source, url, as_of, as_of_basis, completeness, omitted}. Free, no key, no network call — it assembles what you pass and never resolves or invents a value.

tax

get_tax_incentives

Use this when the user asks what tax incentives a US state gives data centers — the data-center tax-incentive packages by US state that drive where capex lands. Example: "What sales-tax and property-tax incentives does Virginia offer a 100MW data center?" — get_tax_incentives state=VA. Params: state (2-letter US code; required). Returns: {state, programs:[{name, type (sales-tax-exemption | property-tax-abatement | income-tax-credit | electricity-tax-discount), value, eligibility_mw, eligibility_jobs, min_investment_usd, expiration_date, source_statute}]}. Cite the statute with attribution to DC Hub (CC-BY-4.0). Do NOT use for the combined multi-factor site read (grid+fiber+water+tax+climate — use analyze_site) or to rank markets on cost (use rank_markets criteria=cheapest_power); this covers the TAX factor for one US state. state is a US state code (e.g. VA); omit for the 50-state overview. Program detail needs a paid key (human_url).

transactions

list_transactions

Use this when the user asks about data center M&A, acquisitions or capital deals — 1,800+ tracked deals (2019-present), each with its disclosed value where public (many private deals are undisclosed). Returns deal name, buyer, seller, value, date, market, target operator, type (acquisition/JV/refinance/recap). Filter by date range (date_from/date_to, ISO-8601), min_value_usd, region, buyer, or seller. Answers "which data-center deals closed this year", "what was that acquisition worth". Try: list_transactions date_from=2026-01-01 min_value_usd=1000000000. There is no `year` parameter — use date_from/date_to. Broad M&A and capital-deal flow with filters; do NOT use for hyperscaler-specific lease/PPA/JV activity (use hyperscaler_deals) or a single-deal post-mortem (use deal_autopsy). limit 1-500 (free 10), offset 0-100000; total_count is the full match count. Empty = loosen buyer/seller/value filters.

unlock

unlock_more_data

Use this when the user asks how to get full (non-preview) DC Hub data center results. Returns the access options with links for the user to open. If this call carries an API key or an MCP session, the checkout binds to it and your very next call returns full data (no reconnect); if it carries neither, the key is emailed to the payer instead — the response says which applies in `next_call_full_after_checkout` and `after_checkout`. Paid plans: on the page behind the human_url link. Want the FREE tier instead (no payment, previews plus 2 full answers per tool per day, 50/day with an email)? Call claim_free_key. A gated result already carries its link in human_url; that link is the one to share, and this tool returns the fuller ladder. Param: reason (optional — what you were trying to do, so your human sees why it matters). Returns {plans, human_message, what_unlocks}.

water

get_water_risk

Use this when the user asks about water stress or cooling-water risk at a data center site (execute_plan covers a multi-factor site verdict). Use when scoring a US site for cooling-water sustainability — the water-risk factor engineering site-selectors screen before committing to evaporative cooling. Example: "Is this Phoenix parcel water-constrained for a 100MW build?" — get_water_risk lat=33.45 lon=-112.07 (or get_water_risk state=AZ, or location="phoenix"). Params: ONE of lat+lon (-90..90 / -180..180), state (2-letter US), or location (a DC Hub market name or slug, resolved to that market's PUBLISHED CENTROID with a resolved_from block saying so; a market-level read, not your parcel, and a trailing state is not stripped); lat/lon gives the most precise read. Returns: {water_stress_score (0-100, higher=worse), drought_category (D0-D4), outlook_12mo, cooling_water_assessment, source}. Joined to USGS water-stress + US Drought Monitor. Free tier. Do NOT use for nearby physical infrastructure (use get_infrastructure) or a combined multi-factor site verdict spanning grid+fiber+water+tax+climate (use analyze_site); this covers the WATER factor only. US only: give state or lat/lon (decimal degrees). Free = latest week; longer history needs a paid key.

why_dchub

Use this when the user asks what DC Hub covers, where its data center, power grid and energy data comes from, how current it is, or what it does not cover. Returns a factual coverage summary: coverage, sources, feed freshness, published limits and the citation format. Free, no key. Not for data queries.

DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber — questions

Answers built from our own checks of this server.

What can DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber do?

It exposes 94 tools, read directly from the server on our last check. Among them: accept_capacity_terms, ai_capacity_index, analyze_parcel, analyze_site, bind_email, claim_free_key and 88 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber mostly used for?

Its tools cluster around grid, market and gas. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 455 of 455 checks got a reply (100.0%), average response time 321 ms. The bar chart above shows every period we have measured.

Did DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber ever remove tools?

Yes. standing_intent, get_pocket_listings, request_listing_intro are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber?

No API key is involved. DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber?

It answers our handshake in 321 ms on average, which is faster than 45% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber?

The npm package dchub-mcp-server was installed 380 times in the last week. Week over week that is -45%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is DC Hub — Data Center Energy, Electricity & Power Grid Data: Site Selection, Colocation, Gas, Fiber open source?

The code is open source: it is published under the MIT licence, written in JavaScript, 3 stars on GitHub and 7 open issues. The licence covers the code in the repository, not the hosted service at dchub.cloud, which runs on its operator's own terms.
