Overview

AI-generated overview

Remote MCP server giving assistants deterministic lookups of UK and US company records, LEIs, domains, FX rates, US geographies, carriers and NWS weather.

What you can do
Search and profile UK companies on Companies House: status, registered office, accounts, charges, directors, owners and filing history, plus US SEC EDGAR profiles, filings and ticker/CIK resolution by name or ticker. Look up Legal Entity Identifiers in the GLEIF register by name or profile, and check domain registration and expiry via registry RDAP. Retrieve ECB euro reference rates for a pair, latest or within the last 90 days. Geocode US addresses and map coordinates to Census geographies, and identify a parcel carrier from a tracking number. Read National Weather Service alerts, forecasts and latest station observations for US locations.
When to use it
Useful when an assistant needs authoritative, source-cited answers about company registration and filings, ownership and directors, entity identifiers, domain ownership or renewal, official exchange rates, US statistical geography, parcel carriers or US weather, without scraping or building its own integrations.
Requirements
Remote streamable HTTP endpoint at api.eckari.com; no local runtime, packages, environment variables or headers declared. Access is metered per call, paid via x402 or an API key. Network access to the endpoint is required.
Before you install
Calls are billed per use through x402 or an API key, so usage can incur spending. Queries about companies, domains, addresses and coordinates are sent to a third-party service. Results reflect public registers and official sources at request time and may be incomplete or stale; geocoded coordinates are interpolated, not rooftop.

Installation

In SourceWeft

  1. Open Capabilities in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.eckari%2Fcapabilities/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

Parameterslimitdetailoffsetcategorycompany_numberrequired

company_uk_owners

List UK company beneficial owners (PSC) from Companies House

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.

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).

Latest 10-K, 10-Q or 8-K for a US company by ticker or CIK

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.

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.

Parametersidrequired

company_us_resolve

Resolve a US company name to its SEC CIK and ticker

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).

Parametersqrequiredlimit

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.

Parametersdomainrequired

domain_registration

WHOIS lookup for a domain, from the registry RDAP record

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).

fx_reference_rate

Get the official ECB reference exchange rate for a pair (accounting, invoicing, reporting)

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).

Parametersbaserequireddatequoterequired

location_us_geocode

Geocode a US street address (Census, TIGER interpolated)

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).

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).

Parameterslatrequiredlonrequired

Detect the carrier from a tracking number

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.

weather_us_alerts

Get active US weather alerts for a point or state (NWS)

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).

Parameterslatlonlimitstatedetailoffset

weather_us_forecast

Get the US weather forecast for coordinates (NWS)

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).

Parameterslatrequiredlonrequiredhoursdetailhourlyperiod_limit

weather_us_observation

Get the latest US weather observation with its age (NWS)

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).
