@mcpolyglot/testkit

MCP conformance harness and test fixtures for mcpolyglot connectors. Drives stdio servers like a real MCP client so connector behavior can be asserted end-to-end.

What's in here

• A minimal MCP client that speaks JSON-RPC over stdio.
• Helpers for spawning a mcpolyglot serve subprocess, listing tools, and calling them.
• Fixture builders for the common shapes (configs, in-memory SQLite, etc.) that connector test suites need.

This package is intended for use inside the mcpolyglot monorepo and by anyone writing a third-party connector who wants to assert that their tools behave correctly under the security pipeline.
