🤖 What is MCP?

The Model Context Protocol (MCP) is an open protocol that enables AI assistants to securely connect to external data sources and tools. Think of it as a standardized way for AI models like Claude to interact with your applications and services.

Key Concepts:

• MCP Server: Provides tools and data (this project!)

• MCP Client: AI assistant that uses the tools (e.g., Claude Desktop)

• Tools: Functions that the AI can call to perform actions

• Protocol: Standardized communication format using JSON-RPC

GitInsight-MCP implements an MCP server that exposes your GitHub profile data to AI assistants, allowing them to answer questions about your repositories, analyze your coding patterns, and generate portfolio insights. I Built This Project

🔧 Technical Stack

🐛 Troubleshooting

Issue: "Missing required environment variables"

Solution: Create a `.env` file with `GITHUB_TOKEN` and `GITHUB_USERNAME`

Issue: "GitHub API rate limit exceeded"

Solution:

• Wait for the rate limit to reset (shown in server logs)

• Use caching (`use_cache: true`)

• Authenticate with a valid token (increases limit to 5000/hour)

Issue: "Invalid GitHub token"

Solution:

• Generate a new token at https://github.com/settings/tokens

• Ensure scopes include: `repo`, `read:user`

• Check for typos in your `.env` file

Issue: Claude Desktop doesn't show the server

Solution:

• Check the config file path is correct for your OS

• Use absolute paths in `claude_desktop_config.json`

• Restart Claude Desktop completely

• Check Claude Desktop logs for errors

Issue: Server crashes on startup

Solution:

• Run `npm run build` first

• Check Node.js version is 18+

• Verify all dependencies installed: `npm install`
