Lightweight Bash MCP Server: Zero Overhead

This project presents a lightweight Model Context Protocol (MCP) server implemented entirely in Bash, avoiding the overhead of heavier runtimes like Node.js or Python. It offers full JSON-RPC 2.0 and MCP protocol support, dynamic tool discovery, JSON configuration, and easy custom tool extension. A simple command-line interface makes it easy to run, with examples showing how to create your own MCP server (a weather server is demonstrated). While lacking concurrency, advanced memory management, and streaming responses, it's sufficient for AI assistants and local tool execution.
