github-insight-mcp

GitHub + npm + PyPI + deps.dev. One question, full picture.

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:

GitHub for stars, activity, and maintenance status
npm/PyPI for version, downloads, and dependencies
deps.dev or Snyk for security vulnerabilities
Repeat for each alternative library

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

Demo: `analyze_repo` Output

You: "Analyze the expressjs/express repository"

Claude calls analyze_repo(owner="expressjs", repo="express"):

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

API	Key Required	Features
GitHub REST API	Optional (free token)	Repository metadata, commits, issues, PRs, contributors, releases, search
npm Registry	No	Package info, download stats
PyPI + pypistats.org	No	Package metadata, download stats
