Tools (2)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • mcp_compliance_explainExplain Compliance Testread-only

    Explain what a specific compliance test ID checks and why it matters. Ids are per spec suite: pass specVersion to read one catalog, or omit it to search both (a shared id whose criteria differ is explained once per suite).

  • mcp_compliance_testRun MCP Compliance Testsread-only

    Run the MCP compliance test suite against a server URL — the spec suite for the server's MCP revision, 2025-11-25 or 2026-07-28, auto-detected unless specVersion pins one. Returns grade (A-F), score, and detailed results covering transport, lifecycle, tools, resources, prompts, errors, schema validation, and security.
