Rs Fast

About

Rs Fast provides a native Rust implementation of the Model Context Protocol (MCP), offering a high-performance, memory-safe, and async-first framework for developing both MCP servers and clients. Leveraging `tokio` and `actix-web`, it supports flexible Stdio and SSE (HTTP) transports, built-in authentication (OAuth, OIDC, JWT) and rate limiting, and zero-cost abstractions for type-safe interfaces. It streamlines the management of tools, resources, and prompts, ensuring efficient and secure communication within the MCP ecosystem.

Key Features

• Memory safety through Rust's ownership model.
• Flexible Stdio (Pipe) and SSE (HTTP) transport support.
• Integrated authentication (OAuth, OIDC, JWT) and rate limiting.
• Zero-cost abstractions for type-safe and efficient interfaces.
• High performance with `tokio` and `actix-web` for non-blocking I/O.
• 1 GitHub stars

Use Cases

• Building high-performance and secure MCP servers.
• Developing robust and async-capable MCP clients.
• Integrating various authentication providers for MCP services.
