Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-08-20. - **Endpoint Security**: 63/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 65/100 - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 9415 tokens (~392/item across 24 items; 24 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability check failed: schema churn in the 2 days we've observed: 0 tool removals, 11 breaking changes, 0 auth/transport breaks, 0 additions. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). ## Install ### Claude ```bash claude mcp add --transport http com-eckari-capabilities https://api.eckari.com/mcp ``` ### Codex ```toml [mcp_servers.com-eckari-capabilities] url = "https://api.eckari.com/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "com-eckari-capabilities": { "type": "remote", "url": "https://api.eckari.com/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add com-eckari-capabilities --url https://api.eckari.com/mcp --transport streamable-http ``` ### Hermes ```yaml mcp_servers: com-eckari-capabilities: url: "https://api.eckari.com/mcp" ``` ### Other ```json { "mcpServers": { "com-eckari-capabilities": { "type": "http", "url": "https://api.eckari.com/mcp" } } } ``` The mcpServers block is a cross-client convention.

Pass back page.next_offset from the previous response to page. - `role` (string): Which appointments to return. Default `director` — the capability's name is its contract. The register encodes the office in officer_role, so the filter is a substring test on it: `director` matches… Output parameters: - `data` (object): Capability output; full JSON Schema at https://api.eckari.com/v1/capabilities/company.uk.directors - `meta` (object) ### `company_uk_filings` (~396 tokens) List UK company filing history from Companies House 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: 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).

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). Input parameters: - `form` (string): Comma-separated EDGAR form types to report the latest filing of. Defaults to "10-K,10-Q,8-K".

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). Input parameters: - `id` (string, required): SEC CIK or exchange ticker symbol. All digits is read as a CIK (leading zeros and an EDGAR CIK prefix are both accepted: 320193, 0000320193, CIK0000320193); anything else is read as a ticker (1-10 ch… Output parameters: - `data` (object): Capability output; full JSON Schema at https://api.eckari.com/v1/capabilities/company.us.profile - `meta` (object) ### `company_us_resolve` (~204 tokens) 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).

Ranking is applied before the limit; page.total reports how many matched in full. - `q` (string, required): Ticker symbol (e.g. AAPL) or company-name fragment (e.g. Apple). Matching is case-insensitive and trimmed; no fuzzy matching is applied. Output parameters: - `data` (object): Capability output; full JSON Schema at https://api.eckari.com/v1/capabilities/company.us.resolve - `meta` (object) ### `domain_expiry` (~168 tokens) Check domain expiry date and days remaining (RDAP) 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). Input parameters: - `domain` (string, required): Bare domain name such as example.com or bbc.co.uk.

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). Input parameters: - `detail` (string): 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. - `hourly` (boolean): 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. - `hours` (integer): Number of hourly periods to return, soonest first.
