Model Context Protocol (MCP)

The official rules and documentation for MCP, a shared standard used by AI apps and tools.

New this week

What it does

This repository is the home of the Model Context Protocol, or MCP. It holds the specification (the written rules of the standard), the protocol schema (a precise technical description of the messages) and the official documentation.

The schema is written in TypeScript and also provided in the JSON Schema format so more programs can use it.

The documentation is published on the project's website, which is the suggested starting point for newcomers.
