What is Model Context Protocol (MCP) Rust SDK?

A Rust implementation of the Model Context Protocol (MCP), designed for seamless communication between AI models and their runtime environments. It is currently a work in progress and not ready for production use.

How to use Model Context Protocol (MCP) Rust SDK?

Add mcp_sdk_rs = "0.1.0" to your Cargo.toml. Then use the provided client and server examples: create a transport (WebSocket or stdio), set up mpsc channels, start a session, and make requests or serve. Both examples use Tokio for async execution.

Key features of Model Context Protocol (MCP) Rust SDK

• Full implementation of MCP protocol specification
• Multiple transport layers (WebSocket, stdio)
• Async/await support using Tokio
• Type-safe message handling
• Comprehensive error handling
• Zero-copy serialization/deserialization

Use cases of Model Context Protocol (MCP) Rust SDK

• Network-based communication between AI models and remote runtime environments
• Local process communication for command-line AI tools and development
• Building custom MCP servers and clients in Rust
• Integrating with WebSocket (WSS/WS) or stdio transports
