Model Context Protocol (MCP)

Minimalistic Rust Implementation Of Model Context Protocol(MCP).

Main repo from Anthropic: MCP

Minimalistic approach

Given it is still very early stage of MCP adoption, the goal is to remain agile and easy to understand. This implementation aims to capture the core idea of MCP while maintaining compatibility with Claude Desktop. Many optional features are not implemented yet.

Some guidelines:

• use primitive building blocks and avoid framework if possible
• keep it simple and stupid
