Last release Aug 18, 2026 · Last commit Aug 20, 2026 · ★ 89,795
Overview
MCP Reference Servers is Anthropic's official repository of educational, reference-grade Model Context Protocol server implementations (Git, Filesystem, Memory, Fetch, and more) spanning Python, TypeScript, Go, and Rust. It exists to demonstrate MCP SDK usage and protocol features for developers building their own servers, not as production-hardened infrastructure. A builder uses it as the canonical starting point and pattern library when implementing a new MCP server for an agent.
