What is GitHub Code Explorer using Model Context Protocol?
This project demonstrates how to implement the Model Context Protocol (MCP) to create a GitHub code search tool that could be used by AI assistants. MCP standardizes how AI models interact with external tools, defining function descriptions, invocation decisions, parameter validation, and result formatting.
How to use GitHub Code Explorer using Model Context Protocol?
Clone the repository, install dependencies with npm install, optionally set the GH_TOKEN environment variable for higher rate limits, then start the server with npm start (or npm run dev for auto-reload). Open http://localhost:3000 in a browser, click “Load Available Functions” to see the API capabilities, and type a query to simulate an AI conversation.
