Key points

  1. Houses the complete specification and official schema definitions for the Model Context Protocol.
  2. Schemas are authored in TypeScript first and published as JSON Schema (e.g. version 2026-07-28) for broad compatibility.
  3. The official documentation website is built with Mintlify and served via modelcontextprotocol.io.
  4. Authored by David Soria Parra and Justin Spahr-Summers under the MIT License.

Why it matters

This repository acts as the authoritative standard for developers implementing MCP clients or servers, ensuring interoperability across tools.

Analysis

The project serves as the standardisation hub for MCP. It relies technically on TypeScript, JSON Schema, and Mintlify for documentation. It is aimed at software engineers and tool builders integrating context into AI systems. With over 9,100 stars, 1,700 forks, and structured release schemas (such as 2026-07-28), the specification appears mature and widely adopted.
