MCP server directory

mcp-spec-test

Black-box conformance suite for any MCP server. Tests the two most recent spec revisions (currently 2026-07-28 and 2025-11-25) against the published schema, plus official-SDK interop.

A conformance suite that tests MCP servers by speaking the protocol over the wire, reporting deviations from the spec, and identifying what could not be checked.
