github-insight-mcp

English | 한국어

An MCP server that combines GitHub repository analysis + npm/PyPI package info + deps.dev security advisories into a single research pipeline. No API keys required. One question gives you stars, forks, activity, downloads, dependencies, and security status.

Why This Exists

Before adopting a library or contributing to a project, developers check:

1. GitHub for stars, activity, and maintenance status

2. npm/PyPI for version, downloads, and dependencies

3. deps.dev or Snyk for security vulnerabilities

4. Repeat for each alternative library

4 sites, 12 tabs, endless context switching. github-insight-mcp does all of this in a single tool call.

Tools

Installation

Automatic Setup (Recommended)

git clone https://github.com/wjddusrb03/github-insight-mcp.git
cd github-insight-mcp
pip install -r requirements.txt
python setup_wizard.py

No API key setup required. Restart Claude Desktop after installation and you're ready to go.

Optional: Set a GitHub Personal Access Token for higher rate limits (60 -> 5,000 requests/hour). The setup wizard will guide you through this.

Manual Setup

1. Install dependencies

git clone https://github.com/wjddusrb03/github-insight-mcp.git
cd github-insight-mcp
pip install -r requirements.txt

2. Add to Claude Desktop config

Open your Claude Desktop config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Linux: ~/.config/claude/claude_desktop_config.json

Add the following to mcpServers:

{
  "mcpServers": {
    "github-insight": {
      "command": "python",
      "args": ["/full/path/to/github-insight-mcp/server.py"]
    }
  }
}

Optional: To use a GitHub token, add an env field:

{
  "mcpServers": {
    "github-insight": {
      "command": "python",
      "args": ["/full/path/to/github-insight-mcp/server.py"],
      "env": {
        "GITHUB_TOKEN": "ghp_your_token_here"
      }
    }
  }
}

Restart Claude Desktop.

API Overview

All APIs are free. GitHub works without a token (60 req/hr) but a free token gives 5,000 req/hr.
