MCP Rust SDK

Rust SDK for the Model Context Protocol

This is a Rust implementation of the Model Context Protocol (MCP), designed to provide both client and server functionalities for seamless integration with Large Language Model (LLM) surfaces.

This is a VERY early repo. If you're interested in contributing, please open an issue or contact [email protected]. A Discord server is planned for the near future!

Overview

The Model Context Protocol standardizes how applications provide context to LLMs, effectively separating context provision from LLM interaction. This Rust SDK fully implements the MCP specification, simplifying the process of:

• Developing MCP clients capable of connecting to any MCP server.
• Building MCP servers that expose resources, prompts, and tools.
• Utilizing standard transports such as stdio and Server-Sent Events (SSE).
• Managing all MCP protocol messages and lifecycle events.
