MCP Rust SDK

Rust SDK for the Model Context Protocol

Rust implementation of the Model Context Protocol (MCP), providing both client and server capabilities for integrating with LLM surfaces.

This is a VERY early repo. Open an issue or contact me at jeanlucthumm@gmail.com if you'd like to get involved. Discord coming soon!

Overview

The Model Context Protocol allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This Rust SDK implements the full MCP specification, making it easy to:

• Build MCP clients that can connect to any MCP server
• Create MCP servers that expose resources, prompts and tools
• Use standard transports like stdio and SSE
• Handle all MCP protocol messages and lifecycle events
