check_mcpsread-onlyWhat has been observed about an MCP server â useful when choosing, adding, or debugging one. Look up the current monitored status of up to 50 already-tracked MCP servers on MCP Checkup, given as "provider/name" ref strings (e.g. "acme/weather-mcp"). Never probes on demand â a ref that doesn't resolve to a tracked target comes back with status "unknown", not an error. Each entry may also be a f
get_mcp_reportread-onlyThe detailed view of one MCP server: every check with its state, plus the observed tool list. Get the full observed report for one already-tracked MCP server on MCP Checkup, by provider/name â includes its full check breakdown and toolset. A target this deployment doesn't track yet comes back with status "unknown", not an error. target may also be a full endpoint URL, a bare domain, or a bare pr
get_mcp_historyread-onlyWhether an MCP server's toolset changed recently. Get recent history for one already-tracked MCP server on MCP Checkup, by "provider/name" ref (e.g. "acme/weather-mcp"). Events include the toolset's most recent change boundary (not a full change-by-change history) plus any recorded baseline-drift events, newest first, up to `limit` results (default 20, max 50). A target this deployment doesn't tra
get_attestationread-onlyThe signed evidence behind a report, for callers that want to inspect it themselves. Get the full signed attestation envelope (DSSE, Ed25519) for one already-tracked MCP server's latest probe run, by "provider/name" ref â the raw envelope plus its issued-at time and declared protocol revision, so a caller can inspect the signed payload rather than trust this tool's own summary of it; the public
search_mcpsread-onlyFind MCP servers by what their tools do. Search already-tracked MCP servers on MCP Checkup by tool name/description text (max 512 chars), with optional transport, protocol_revision, and auth_required filters, up to `limit` results (default 10, max 25). Ordered by text-match relevance and then recency only â never by price or paid tier. Each result's summary is machine-generated from observed too
request_checkAsk for a one-off public observation of the MCP server at a full endpoint URL â this is the only tool here that contacts a third-party server, and it contacts exactly the host you name. `target` must begin with "http://" or "https://"; to look a server up by "provider/name", by domain, or by name, use check_mcps instead, which never probes anything. The result is not signed, is not stored as a r
