Model Context Protocol Specification
Our summary
The open protocol standardizing how LLM applications connect to external tools and data — JSON-RPC messages, stateful connections, and explicit client/server capability negotiation (the 'handshake').
Why it matters
The contract an integration test must hold the system to: the handshake, tool schemas, and capability negotiation are exactly the deterministic seams that break silently.
