What MCP Conformance Test Framework does
A framework for testing MCP (Model Context Protocol) client and server implementations against the specification.
Why teams reach for it: An SDK can run exactly what a chosen spec revision requires, with every JSON-RPC message on the wire additionally validated against that revision's JSON schema, and a YAML baseline of known failures so the run exits non-zero only on a new regression or a stale baseline entry.

How will you inspect behavior and fix failures?
Inspectors & debugging tools let developers see what's happening inside an MCP connection and fix problems when something breaks.
