This is a Rust implementation of the Model Context Protocol SDK that maintains API compatibility with the official TypeScript SDK. If you're building MCP servers in Rust and want the performance and safety benefits of the language while keeping parity with the TypeScript ecosystem, this is your path forward. The focus here is on providing a production-grade SDK rather than a specific integration, so you'd reach for this when you're developing your own MCP server in Rust. It handles the protocol layer so you can focus on implementing your tools, resources, and prompts without worrying about wire format compatibility or type safety issues that come with rolling your own protocol implementation.
