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

company

company_uk_accounts

Return the accounts filing status of a UK company from the Companies House register — the accounting reference date, the last accounts filed (type and period), the next accounts due date and a derived overdue flag. Use when: When are this UK company's accounts due? Not for: You need financial figures (turnover, profit, balance sheet) — not on the public register API. Related: company_uk_filings; company_uk_profile; company_uk_status. Price: USD 0.003/call (x402), 0.002 (account key).

company_uk_charges

Charges registered against a UK company at Companies House — mortgages, debentures and other security — with dates, classification, particulars and the persons entitled. Use when: Establish whether a UK company has outstanding security over its assets, and who holds it. Not for: You need insolvency proceedings — not currently supported (see the resource flags on company.uk.profile). Related: company_uk_profile; company_uk_filings; company_uk_status. Price: USD 0.006/call (x402), 0.005 (account key).

company_uk_directors

Directors of a UK company from the Companies House officers register — the register of directors, secretaries and LLP members — including corporate and nominee directors, with appointment and resignation dates, nationality, country of residence, occupation, month/year of birth and correspondence address. Use when: Identify who is legally responsible for a UK company - the directors on the Companies House officers register. Not for: You need beneficial owners / persons with significant control — use company.uk.owners. Price: USD 0.005/call (x402), 0.004 (account key).

company_uk_filings

Return the filing history of a UK company from the Companies House register — accounts, confirmation statements, officer appointments, address and capital changes, resolutions and mortgages — most recent first, optionally filtered by category, with date, form type (AA, CS01, AP01, TM01), the readable register description, registrar annotations and a document_url for every filed image. Use when: What has this UK company filed recently? Not for: You need the current directors themselves rather than the filing events — use company.uk.directors. Price: USD 0.005/call (x402), 0.004 (account key).

company_uk_owners

An empty items list is never the same as "no owner": ownership_status and the filed PSC statements/exemptions explain why the register discloses none. Use when: Who owns this UK company? Not for: You need directors/officers rather than owners — use company.uk.directors. Related: company_uk_directors; company_uk_profile; company_uk_status. Price: USD 0.008/call (x402), 0.006 (account key).

company_uk_profile

Return the core registered profile of a UK company from the Companies House register: name, status with derived is_active and is_striking_off, type, jurisdiction, incorporation and cessation dates, SIC codes with their official UK SIC 2007 descriptions, registered office address, previous names, and the accounts and confirmation-statement summary. Use when: You have a UK company number and need the standard registered record. Not for: You only need to know if the company is active — use company.uk.status (cheaper). Price: USD 0.004/call (x402), 0.003 (account key).

company_uk_registered_office

Return the current registered office address of a UK company from the Companies House register as structured fields (premises, address lines, locality, region, postcode, country) plus a single-line rendering for correspondence, address matching and verification. Use when: What is the registered office address of company 00445790? Not for: You need the whole registered profile as well — use company.uk.profile (it already includes this address). Related: company_uk_profile; company_uk_status; company_uk_search. Price: USD 0.003/call (x402), 0.002 (account key).

company_uk_search

Search the UK Companies House register by name or keyword and return matching companies with company number, register status and a derived is_active, type, incorporation and cessation dates and the register's one-line address snippet. Use when: Look up a UK company by name. Not for: You already have the company number — call company.uk.profile or company.uk.status directly. Related: company_uk_status; company_uk_profile; company_uk_directors; company_uk_owners. Price: USD 0.002/call (x402), 0.0015 (account key).

company_uk_status

Return the current legal status of a UK company from the Companies House register — active, dissolved, liquidation, administration, receivership, voluntary-arrangement and others — with status detail, cessation date, a derived is_active (true for the live-on-the-register statuses active, open and registered) and a derived is_striking_off for an active company with a proposal to strike off. Use when: Is this UK company still active? Not for: You need the full registered profile (type, SIC codes, incorporation date) — use company.uk.profile. Price: USD 0.003/call (x402), 0.002 (account key).

company_us_filings

Return the recent EDGAR filing history of a US company identified by stock ticker (AAPL) or CIK, optionally filtered by form type and filing date and paged. Use when: List every 8-K on this ticker's EDGAR index this year, with links to the documents. Not for: You need to know who submitted a filing — EDGAR's submissions index carries no filer identity, so a Form 4 or SCHEDULE 13G here tells you the filing exists, not who made it. Related: company_us_filings_latest; company_us_profile; company_us_resolve; company_uk_filings. Price: USD 0.005/call (x402), 0.004 (account key).

company_us_filings_latest

Give a stock ticker (AAPL) or CIK and get the most recent EDGAR filing of each requested form — by default the latest 10-K, 10-Q and 8-K — with filing and report dates and a direct sec.gov link to each primary document. Use when: What is Apple's latest 8-K, and where is the document? Not for: You need to know who submitted the filing — EDGAR's submissions index carries no filer identity, and for ownership forms (3, 4, 5, SCHEDULE 13G) the submitter is a third party, not the company. Price: USD 0.003/call (x402), 0.002 (account key).

company_us_profile

Look up an SEC filer by stock ticker (AAPL) or CIK and return its registered profile — legal name, entity type, SIC industry code and description, EIN, filer category, fiscal year end, state of incorporation, tickers and exchanges, former names, business and mailing addresses and phone. Use when: Which exchanges and tickers does this filer trade under? Not for: You need to know whether the filer is still submitting periodic reports — check the filing dates with company.us.filings.latest; EDGAR publishes no reporting-status field. Price: USD 0.004/call (x402), 0.003 (account key).

company_us_resolve

Turn a company-name fragment or stock ticker into the SEC EDGAR identifiers. Use when: Which SEC filer and CIK does the company name "Apple" belong to? Not for: You already have a ticker or a CIK and want profile or filings — company.us.profile, company.us.filings and company.us.filings.latest accept either identifier directly, so this extra call is unnecessary. Related: company_us_profile; company_us_filings_latest; company_us_filings; entity_lei_search. Price: USD 0.002/call (x402), 0.0015 (account key).

weather

weather_us_alerts

Active National Weather Service watches, warnings and advisories for a US coordinate or a two-letter state or marine area code - event, severity, certainty, urgency, headline, affected areas and zone codes, and effective/onset/expiry times in UTC. Read at request time, so an empty list means nothing is active. Use when: Decide whether an active US weather warning affects a location before dispatching or travelling. Not for: You need the forecast rather than alerts - use weather.us.forecast. Related: weather_us_forecast; weather_us_observation. Price: USD 0.003/call (x402), 0.002 (account key).

weather_us_forecast

Official National Weather Service forecast for any US coordinate - six 12-hour day/night periods by default, or hourly - each with temperature in C and F, precipitation probability, a wind speed range in km/h, wind direction and a short forecast, plus the NWS issue time so an agent can judge its age. Use when: What is the weather forecast for these US coordinates? Not for: You need the latest observed conditions and their age - use weather.us.observation. Related: weather_us_observation; weather_us_alerts. Price: USD 0.003/call (x402), 0.002 (account key).

weather_us_observation

Latest surface observation from the nearest National Weather Service station to a US coordinate, with the station identity, the observation time (observed_at), its age in seconds and an is_stale flag. Station observations are reported roughly every 20-60 minutes, so this is the most recent measurement, not a real-time reading. Use when: What was the most recently observed temperature at these US coordinates? Not for: You need a prediction rather than a measurement - use weather.us.forecast. Related: weather_us_forecast; weather_us_alerts. Price: USD 0.003/call (x402), 0.002 (account key).

domain

domain_expiry

Registry expiry date for a domain read live from the authoritative registry RDAP server, with whole days remaining, the registry status codes, the registrar name and the registry's own last-update timestamp. A focused, cheaper subset of domain.registration for renewal monitoring and portfolio checks. Use when: When does this domain expire? Not for: You also need nameservers, DNSSEC, the creation date or the registrar's abuse contact - use domain.registration. Related: domain_registration. Price: USD 0.002/call (x402), 0.0015 (account key).

domain_registration

The WHOIS lookup for a domain, answered from the registry's own RDAP service - the structured successor to port-43 WHOIS, read live via the IANA bootstrap, never scraped WHOIS text. Use when: Answer a WHOIS question about a domain - registrar, creation date, expiry, transfer lock - from the registry record. Not for: You only need the expiry date and days remaining - use domain.expiry (cheaper). Related: domain_expiry. Price: USD 0.004/call (x402), 0.003 (account key).

entity

entity_lei_profile

Return the registry-authoritative GLEIF record for a Legal Entity Identifier — legal and previous names, legal and headquarters addresses, jurisdiction, legal form, entity and registration status, renewal dates (with days until renewal), managing LOU, corroboration level, BIC codes and the named local registry. Use when: Look up everything the LEI register holds for this identifier. Not for: You only have a company name — use entity.lei.search first. Related: entity_lei_search; company_uk_profile; company_uk_status; company_us_profile. Price: USD 0.004/call (x402), 0.003 (account key).

entity_lei_search

Find Legal Entity Identifiers by company name in the global GLEIF register, optionally narrowed to one country. Returns the LEI, legal name, registration and entity status, jurisdiction, legal address and the local registry the entity is registered at — the identifier bridge between national company registers worldwide. Use when: What is the LEI for this company? Not for: You already have the LEI — use entity.lei.profile. Related: entity_lei_profile; company_uk_search; company_us_resolve. Price: USD 0.003/call (x402), 0.002 (account key).

location

location_us_geocode

Convert a one-line US street address into coordinates using the US Census Bureau Geocoder. Returns the standardised matched address, latitude and longitude to 6 decimal places, the TIGER/Line segment and parsed address components. Coordinates are interpolated along street address ranges, not rooftop or parcel positions. Use when: Convert this US street address to latitude and longitude. Not for: You need rooftop or parcel-level precision — Census coordinates are TIGER address-range interpolations. Related: location_us_geographies. Price: USD 0.003/call (x402), 0.002 (account key).

location_us_geographies

Return the US Census Bureau geographies containing a latitude/longitude — state, county, census tract, block group, census block, incorporated place, congressional district and ZIP Code Tabulation Area — each with its FIPS or GEOID. The standard way to attach official US statistical geography to a point. Use when: Which county and census tract is this coordinate in? Not for: You have an address rather than coordinates — use location.us.geocode first. Related: location_us_geocode. Price: USD 0.003/call (x402), 0.002 (account key).

parcel

parcel_detect_carrier

Identify which carrier issued a tracking number using a deterministic, versioned signature set - prefixes, lengths, carrier check digits and UPU S10 structure - returning the carrier, how distinctive the match is, every ranked candidate with typed evidence, and the parsed S10 details. No upstream call and no carrier account required. Use when: Which carrier is this tracking number from? Not for: You need tracking events, status or delivery estimates - not yet available. Price: USD 0.001/call (x402), 0.001 (account key).

reference

fx_reference_rate

European Central Bank euro foreign exchange reference rate for a pair - the official daily fix used for accounting, invoicing and reporting - latest or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed from the same fix and named in rate_derivation. Use when: Convert or report an amount at an official daily rate both sides of a contract can verify against the ECB. Not for: You need an executable, tradable, live or intraday market rate - this is a daily fix only. Price: USD 0.002/call (x402), 0.0015 (account key).

Capabilities — questions

Answers built from our own checks of this server.

What can Capabilities do?

It exposes 24 tools, read directly from the server on our last check. Among them: company_uk_accounts, company_uk_charges, company_uk_directors, company_uk_filings, company_uk_owners, company_uk_profile and 18 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 Capabilities mostly used for?

Its tools cluster around company, weather and location. 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 Capabilities 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 275 ms. The bar chart above shows every period we have measured.

How do I connect Capabilities?

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 Capabilities need an API key?

No. Capabilities completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 24 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Capabilities?

It answers our handshake in 275 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
