Enables teams to build production-grade MCP servers in Rust, eliminating performance bottlenecks and complexity when integrating Claude with backend systems.

A Rust SDK for building MCP servers and clients — a developer library, not a ready-made server you plug into Claude. Implements the latest MCP protocol (2025-11-25), passes 100% of official MCP conformance tests, and supports stdio, Streamable HTTP, and SSE transports with Axum/Actix integrations, OAuth, and procedural macros for defining tools. For Rust engineers writing their own MCP integrations; the authors note the project is still under active development.

Build a custom MCP server that handles real-time data streaming from your infrastructure.
Create an asynchronous Rust client to integrate Claude with your internal tooling platform.
Develop a high-performance MCP bridge connecting Claude to your legacy Rust applications.
