pip Package README MCP Server

An MCP (Model Context Protocol) server that enables AI assistants to fetch comprehensive information about Python packages from PyPI, including README content, package metadata, and search functionality.

Features

• Package README Retrieval: Fetch formatted README content with usage examples from Python/pip packages hosted on PyPI
• Package Information: Get comprehensive package metadata including dependencies, versions, statistics, and maintainer information
• Package Search: Search PyPI with advanced filtering by package type, popularity, and relevance
• Smart Caching: Intelligent caching system to optimize API usage and improve response times
• GitHub Integration: Seamless integration with GitHub API for enhanced README fetching when packages link to GitHub repositories
• Error Handling: Robust error handling with automatic retry logic and fallback strategies

MCP Client Configuration

Add this server to your MCP client configuration:

{
  "mcpServers": {
    "pip-package-readme": {
      "command": "npx",
      "args": ["pip-package-readme-mcp-server"],
      "env": {
        "GITHUB_TOKEN": "your_github_token_here"
      }
    }
  }
}

Note: The GITHUB_TOKEN is optional but recommended for higher API rate limits when fetching README content from GitHub.
