This one needs environment variables set before it will start: TENSORFEED_TOKEN (Bearer token from /api/payment/buy-credits. Required for paid tiers (full verdicts, 8 to 90 day series, webhook watches, account status). Free tiers (news, status, pricing, verdict previews, 1 to 7 day series, model discovery) work without it. Buy credits in USDC on Base at https://tensorfeed.ai/developers/agent-payments.). The author declared them in the registry entry; get the values from the project itself.

Available tools 27

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

agent

check_agent_reputation

Look up an agent's public reputation card from the TensorFeed Agent Reputation Bureau. Takes a wallet (0x + 40 hex) OR a token_prefix (first 16 chars of a tf_live_ bearer). Returns the full ReputationCard: composite + sub-metric ranks (reliability, spend, activity, streak), trust grade A through F, public flags (new_wallet, spend_spike, claim_disputed, etc), wallet age, first_seen, last_active, ofac_clean, banned + ban_reason if applicable. Cards rebuild daily at 04:50 UTC from TF's own observable telemetry. Returns ok=false with status=not_found for unknown identities so callers can distinguish "we have no record" from "we have a record showing zero activity". Useful for: marketplaces routing work to high-grade agents, peer agents deciding to trust another agent, ops dashboards monitoring an agent's standing, or operators inspecting their own reputation before claiming a wallet.

get_agent_opportunities

Get TensorFeed's daily scan of new repositories across the AI agent ecosystem (Anthropic, OpenAI, Microsoft, ModelContextProtocol, HuggingFace, LangChain, frontier labs) plus recent MCP/x402/skills keyword sweeps. Each opportunity includes the GitHub repo path, description, stars, last update, the source signal, and a composite score (signal weight × log10(stars+1) × recency decay). Refreshed daily at 13:30 UTC. Useful for surfacing distribution targets, integration ideas, or just a daily digest of what's launching across the agent space. License: GitHub data via the public Search API; output is TensorFeed's curated ranking.

search_agent_directory

Search the TensorFeed Agent Self-Directory for hireable AI agents. Filter by skill (from a controlled vocab including research, data-analysis, coding, content-writing, voice-acting, image-generation, etc), service_area (research/data/coding/writing/voice/image/video/other), language (BCP 47), availability, hourly rate cap, minimum years of experience, or verified-hireable status. Verified-hireable members (operators paying $5 USDC/30 days for top-tier visibility) sort first. Free tier capped at 25 results. Returns wallet, display_name, operator_url, skills, rates, languages, years_experience, composite reputation rank, trust grade. TF publishes self-descriptions; TF takes no fee from off-platform transactions between operators and the agents who contact them.

osv

get_osv_advisory_by_id

Look up a single OSV.dev advisory by ID. Accepts GHSA / CVE / PYSEC / RUSTSEC / GO / OSV / DSA / ALPINE / DEBIAN / UBUNTU and other documented identifier prefixes. License: Apache 2.0.

get_osv_advisory_for_package

Cross-ecosystem vulnerability advisory lookup via OSV.dev. Given an ecosystem (PyPI, npm, Go, crates.io, Maven, NuGet, RubyGems, Packagist, etc) and a package name (optional version), returns advisories affecting that package. License: Apache 2.0.

sec

get_sec_submissions

Get entity metadata + recent filings for one company by CIK. Accepts canonical zero-padded CIK ("0000320193"), bare numeric ("320193"), or "CIK0000320193" prefixed. Returns full company profile (name, tickers, exchanges, EIN, SIC, addresses) plus the most-recent ~1000 filings. License: US Government public domain.

search_sec_edgar

Lucene-style full-text search across the entire SEC EDGAR public-filings corpus since the 1990s. Forms include 10-K (annual), 10-Q (quarterly), 8-K (current event), DEF 14A (proxy), S-1 (IPO), 13F (institutional holdings), and ~70+ others. License: US Government public domain. The killer endpoint for finance and equity-research agents.

cve

get_cve_record

Look up a single CVE Record v5.2 from the MITRE CVE List by ID (e.g. CVE-2024-3094). Lazy-fetched and cached 7 days. License: MITRE CVE Terms of Use, commercial redistribution permitted; the response includes the standard attribution block.

directory

list_directory_skills

Return the distribution of skill tags across all active operator claims on the TensorFeed Agent Directory. Sorted by count desc. Useful for agents discovering what kinds of work other operators advertise on TF, OR for agent-marketplaces wanting to mirror TF's controlled vocab.

eia

get_eia_series

Get a US Energy Information Administration time-series. Curated routes: petroleum/pri/spt (WTI/Brent crude spot prices), petroleum/pri/gnd (US retail gasoline), natural-gas/pri/sum (Henry Hub + retail nat gas), electricity/retail-sales (by state and sector), electricity/electric-power-operational-data (net generation by fuel), total-energy. License: US Government public domain.

epss

get_epss_score

Get the EPSS (Exploit Prediction Scoring System) probability for one CVE, sourced from FIRST.org. Returns the daily probability (0-1) that the CVE will be exploited in the next 30 days plus a percentile rank. License: FIRST.org free-for-any-use.

fda

query_fda

Query any openFDA dataset: drug adverse events (FAERS), drug labeling (SPL), drug recalls, food recalls, or medical device events. Pick the dataset with the dataset argument. Uses openFDA Lucene-style search syntax (e.g. "patient.drug.medicinalproduct:aspirin", "openfda.brand_name:tylenol"). License: openFDA CC0 1.0 Universal Dedication, FDA waiver of all copyright; commercial redistribution permitted.

free

check_free_tier_status

Check the caller IP's free premium-API trial quota. TensorFeed gives 100 free /api/premium/* calls per IP per 24h rolling window with no auth required. This tool returns used_today, remaining, and resets_at without consuming a quota slot. Use it before deciding whether to make a paid call versus waiting for the trial reset. No arguments.

kev

get_kev_catalog

Get the CISA Known Exploited Vulnerabilities (KEV) catalog. Returns the most recent N entries plus catalog metadata. Refreshed daily at 06:30 UTC. License: US Government public domain. ~1500 actively-exploited CVEs.

lookup

lookup_sec_company_ticker

Resolve a stock ticker symbol (e.g. AAPL, MSFT, NVDA) or numeric CIK to the canonical SEC entity record. Returns ticker, CIK, company name, and exchange. Pair with get_sec_submissions to retrieve filings. License: US Government public domain.

models

get_models

Get the model pricing and specs catalog across providers (Anthropic, OpenAI, Google, Meta, Mistral, Cohere, etc). Includes per-token pricing, context windows, capabilities, deprecation flags. Refreshed daily.

news

get_news_articles

Get the latest AI news articles aggregated from 12+ sources (Anthropic, OpenAI, Google, HuggingFace, TechCrunch, The Verge, Hacker News, etc). Polled every 10 min, deduplicated, sanitized for prompt injection. Returns up to 200 articles with title, snippet, source, and publishedAt.

recent

get_recent_earthquakes

Get recent earthquakes from the US Geological Survey's pre-built summary feeds. Choose a magnitude bucket (significant | 4.5 | 2.5 | 1.0 | all) and a time window (hour | day | week | month). Returns a flattened list with id, magnitude, place, time (ISO 8601), depth_km, longitude, latitude, tsunami flag, USGS detail URL. Upstream feeds refresh every minute. License: US Government public domain (17 USC §105).

register_free_watch

Register a free webhook subscription. TensorFeed POSTs HMAC-signed deliveries to your callback_url when the watch spec fires (price drop, status change, leaderboard rank shift, macro indicator threshold crossing, etc). 5 watches per IP, 25 fires per watch, 30-day TTL. Same delivery infrastructure as paid /api/premium/watches. If you omit secret, TensorFeed generates one and returns it; you cannot retrieve it again later. Same IP for management; manage via the REST endpoints under /api/watches/free/{id}.

research

get_research_papers

Get recent AI/ML research papers from one of three feeds, chosen with the source argument. arxiv_recent is the firehose: newest arXiv submissions in cs.AI / cs.LG / cs.CL / cs.CV by submission date, refreshed daily at 11:30 UTC. trending is citation-ranked from Semantic Scholar across five fan-out queries, deduped, refreshed daily at 11:00 UTC. hf_daily is Hugging Face editor-curated with community upvotes and discussion counts, refreshed daily at 14:15 UTC. Pick arxiv_recent for what is brand new, trending for what is influential, hf_daily for what practitioners are discussing. License: arXiv and Semantic Scholar permit metadata use; the standard attribution block ships on every response.

route

route_verdict

PREMIUM (1 credit, $0.02). The signed model-routing decision: for a task (code, reasoning, creative, general) or a named model, returns the single best model to use right now, fusing pricing, benchmark capability discounted for contamination, real production usage, measured p95 latency, and live operational state, with runners-up and an AFTA-signed receipt over the inputs. Pay per call with an x402 wallet payment (arguments.payment, or an X-PAYMENT header; strict HTTP-402 transport at https://mcp.tensorfeed.ai/mcp?x402=strict) or use an Authorization: Bearer tf_live_... credits token. No token and no USDC? Claim free trial credits by signing a wallet message at https://tensorfeed.ai/api/payment/trial-credits.

status

get_status_summary

Get the live operational status of every major AI service tracked by TensorFeed (Claude, ChatGPT, Gemini, Perplexity, Cohere, Mistral, HuggingFace, Replicate, Midjourney, etc). Polled every 2 min. Returns operational | degraded | down per service plus the most recent incident.

submit

submit_wantlist_item

Submit a wantlist entry telling TensorFeed what data you wish was served. Aggregated patterns inform TF's pipeline priorities. Anonymous by default, no PII collected, items expire after 30 days. Per-IP rate limit 5 submissions per 24h. Signal collector, not a contract.

supply

check_ai_supply_chain_risk

Check the TensorFeed AI/MCP/LLM supply-chain IOC feed. Returns publicly-disclosed malicious npm/PyPI packages whose name or summary signals relevance to AI agent operators. With no args, returns the whole snapshot (typically a small number of entries). With "package_name", returns only entries matching that name (substring, case-insensitive) so an agent can ask "is X risky right now?" before installing. Each entry cites its GHSA primary source. Posture: TF republishes already-public advisories; the listed primary source is authoritative.

verified

get_verified_hireable_status

Look up whether a specific wallet has an active verified-hireable subscription on the TensorFeed Agent Directory. Returns { verified_hireable: bool, verified_hireable_until?: ISO } for a given wallet. Useful for downstream marketplaces or peer agents who want to confirm a published-rate or active-availability badge is current before routing work to that wallet.

weather

get_weather_alerts

Get active US weather alerts from the National Weather Service. US-only coverage. Filter by 2-letter state code (area), exact event name (e.g. 'Tornado Warning', 'Heat Advisory'), severity (Extreme | Severe | Moderate | Minor | Unknown), urgency (Immediate | Expected | Future | Past | Unknown), and status (actual | exercise | system | test | draft). Returns a flattened alerts list with id, event, severity, urgency, headline, description, areaDesc, sent/effective/expires/ends, sender_name, web URL. Refreshed in real time upstream; cached 60s. License: US Government public domain (17 USC §105).

whats

whats_new

PREMIUM (1 credit, $0.02). The full TensorFeed morning brief: every AI headline in the window with links, model pricing deltas, and incident detail, AFTA-signed. The free preview sibling (/api/preview/whats-new, 10 calls/IP/day) returns only summary counts plus the top 3 headline titles; this paid call returns the complete brief with no rate limit. Pay per call with an x402 wallet payment (arguments.payment, or an X-PAYMENT header; strict HTTP-402 transport at https://mcp.tensorfeed.ai/mcp?x402=strict) or use an Authorization: Bearer tf_live_... credits token. No token and no USDC? Claim free trial credits by signing a wallet message at https://tensorfeed.ai/api/payment/trial-credits. Returning caller? Pass since=<cursor> from your last brief and an unchanged poll is free (no credit charged); you pay only when something new has broken since that cursor.

TensorFeed — questions

Answers built from our own checks of this server.

What can TensorFeed do?

It exposes 27 tools, read directly from the server on our last check. Among them: check_agent_reputation, check_ai_supply_chain_risk, check_free_tier_status, get_agent_opportunities, get_cve_record, get_eia_series and 21 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 TensorFeed mostly used for?

Its tools cluster around agent, osv and sec. 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 TensorFeed working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 310 ms. The bar chart above shows every period we have measured.

Did TensorFeed ever remove tools?

Yes. get_ai_trending_papers, get_arxiv_recent, get_hf_daily_papers, query_fda_device_events and 4 more 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 TensorFeed?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does TensorFeed need an API key?

No. TensorFeed completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 27 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is TensorFeed?

It answers our handshake in 310 ms on average, which is faster than 49% 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 TensorFeed?

The npm package @tensorfeed/mcp-server was installed 1 189 times in the last week. Week over week that is +956%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is TensorFeed open source?

Yes — it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
