mcpydoc 0.5.0

Model Context Protocol (MCP) server providing documentation and code analysis for Python packages

MCPyDoc - Python Package Documentation MCP Server

MCPyDoc is a Model Context Protocol (MCP) server that provides comprehensive documentation and code analysis capabilities for Python packages. It enables AI agents like Cline and GitHub Copilot to understand and work with Python codebases more effectively, especially when working with private libraries and unfamiliar packages.

✨ Features

• 📚 Package Documentation: Get comprehensive docs for any Python package
• 🔍 Symbol Search: Find classes, functions, and modules by pattern
• 💻 Source Code Access: Retrieve actual implementation code
• 🏗️ Structure Analysis: Analyze complete package architecture
• 🔧 Type Hints: Extract and analyze type annotations
• 📖 Docstring Parsing: Support for Google, NumPy, and Sphinx formats
• 🏃 High Performance: Efficient caching and optimized operations
• 🛡️ Error Handling: Robust error management and validation

🚀 Quick Start

Installation

# Install from PyPI (Recommended)
pip install mcpydoc

# Or install from source
git clone https://github.com/amit608/MCPyDoc.git
cd MCPyDoc
pip install .

Once installed and configured with your AI agent, the server will automatically start when needed.

🔌 Integration with you favorite coding AI agent
