"Handshake" matching MCP servers:

Enables agents to inspect and diagnose their own MCP setup by exposing read-only tools that audit configured servers, report which coding agents have configs, surface misplaced or duplicated registrations, and list curated preset packs. It also powers CLI workflows for checking handshake, tool lint, and tool-surface quality scores of any stdio server.

Launches any MCP server as a real client would, running the handshake, inspecting every tool's schema and description, and deliberately making a bad tool call to test error handling. Returns one deterministic, evidence-backed score with named issues so servers can be verified before users' agents hit them in production.
