Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability63
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 10063 tokens (~419/item across 24 items; 24 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "company_uk_charges" implies "charge" and declares readOnlyHint instead, contradicting what its own name says it does. See how to fix → Fail
  • An AI judge read all 25 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass
Install

How do I install the com.eckari/capabilities MCP server?

com.eckari/capabilities is a hosted endpoint at https://api.eckari.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

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.

company_uk_filings ~477

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.

company_us_filings ~418

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).

NameTypeReqDescription
formstring–Comma-separated EDGAR form types to keep, e.g. "10-K,10-Q,8-K". Matching is exact and case-insensitive; omit to return every form.

company_us_filings_latest ~336

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).

NameTypeReqDescription

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 ~204

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).

domain_expiry ~168

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).

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).

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.

fx_reference_rate ~261

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).

NameTypeReqDescription

location_us_geocode ~261

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).

NameTypeReqDescription
addressstringyesOne-line US street address including city and state, e.g. "1600 Pennsylvania Ave NW, Washington, DC 20500".

location_us_geographies ~185

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).

NameTypeReqDescription
latnumberyesLatitude in decimal degrees (WGS 84), e.g. 38.8977.
lonnumberyesLongitude in decimal degrees (WGS 84), negative in the western hemisphere, e.g. -77.0365.

parcel_detect_carrier ~242

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).

NameTypeReqDescription
destination_countrystring–Optional ISO 3166-1 alpha-2 destination country hint. Used only as a small tie-breaker; it never invents a candidate.
origin_countrystring–Optional ISO 3166-1 alpha-2 origin country hint. Used only as a small tie-breaker; it never invents a candidate.
tracking_numberstringyesTracking or consignment number. Spaces and hyphens are removed and letters upper-cased before matching (4-40 letters and digits after normalisation). Digits and letters are never altered.

weather_us_alerts ~430

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 ~382

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).

NameTypeReqDescription
detailstring–compact (default) returns the fields an agent acts on. full adds the NWS narrative (detailed_forecast), the icon URL, the trend note and, for hourly periods, dewpoint_c and humidity_pct.
hourlyboolean–Return hourly periods instead of the default 12-hour day/night periods. Hourly periods have no name and, at detail=full, carry dewpoint and humidity.

weather_us_observation ~197

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).
