Observed from public registry data and a read-only, unauthenticated check on 2026-10-23. Not a certification: AAIF and the MCP project don't certify servers, and these lines are signals, not pass/fail. They don't change the Copilot Studio verdict. Own this server? modelcontextprotocol/conformance: test your own server.
