Python Project MCP Service 🐍

A powerful Model Context Protocol (MCP) service that enables Claude to intelligently explore, understand, and analyze Python projects. This service provides Claude with comprehensive tools to navigate codebases, analyze dependencies, search code patterns, and understand project structure automatically.

🚀 Features

Intelligent Project Discovery: Automatically identifies Python projects and their structure
Comprehensive Code Analysis: Reads and analyzes Python files, configurations, and documentation
Dependency Mapping: Extracts and analyzes dependencies from various requirement files
Smart Code Search: Pattern-based searching across your entire codebase
Project Structure Visualization: Interactive directory tree exploration
Resource Management: Efficient handling of large codebases with smart filtering

📋 Prerequisites

Python 3.8 or higher
Poetry (recommended) or pip for dependency management

    "python-project": {
      "command": "cmd",
      "args": ["/c", "cd /d C:\\Users\\YourUsername\\Projects\\python-project-mcp && poetry run python python_project_mcp.py"]
    }
  }
}

Windows with Direct Path:

{
  "mcpServers": {
    "python-project": {
      "command": "C:\\Users\\YourUsername\\Projects\\python-project-mcp\\.venv\\Scripts\\python.exe",
      "args": ["C:\\Users\\YourUsername\\Projects\\python-project-mcp\\python_project_mcp.py"]
    }
  }
}

macOS/Linux with Poetry:

{
  "mcpServers": {
    "python-project": {
      "command": "bash",
      "args": ["-c", "cd /Users/yourusername/projects/python-project-mcp && poetry run python python_project_mcp.py"]
    }
  }
}

macOS/Linux with Direct Path:

{
  "mcpServers": {
    "python-project": {
      "command": "/Users/yourusername/projects/python-project-mcp/.venv/bin/python",
      "args": ["/Users/yourusername/projects/python-project-mcp/python_project_mcp.py"]
    }
  }
}

Restart Claude Desktop to load the new MCP service.

🧪 Testing the Installation

Local Testing

Before configuring with Claude, test the service locally:

Using Poetry (Recommended):

# Navigate to your project directory
cd /path/to/your/project

# Run the service with Poetry
poetry run python python_project_mcp.py

Using Virtual Environment:

# Activate your virtual environment
.venv\Scripts\activate.bat  # Windows
# or
source .venv/bin/activate   # macOS/Linux

# Run the service
python python_project_mcp.py

The service should start and wait for MCP protocol messages.

Testing with Claude

Open Claude Desktop
Start a new conversation
Try the following command to verify the service is working:
```
Set the project root to "/Users/yourusername/projects/your-python-project"
```
Example paths:
- Windows: "C:\Users\YourUsername\Projects\MyPythonApp"
- macOS: "/Users/yourusername/projects/my-python-app"
- Linux: "/home/yourusername/projects/my-python-app"

If successful, Claude will confirm the project root is set and show Python project indicators found.

🐛 Troubleshooting

Common Issues

Service not appearing in Claude: Ensure the path in claude_desktop_config.json is correct and Claude Desktop has been restarted.
Permission errors: Make sure the Python executable and script have proper permissions.
Module import errors: Verify that the virtual environment is properly activated and MCP is installed.
Large file errors: The service has a 1MB file size limit. For larger files, consider using the search functionality instead.

Debug Mode

To enable debug logging, modify the logging level in the script:

logging.basicConfig(level=logging.DEBUG)
