What It Does

This package automatically:

• Finds Python: Locates a Python 3.8+ interpreter on your system
• Installs Dependencies: Downloads and installs the OHM MCP Python package if needed
• Launches Server: Starts the MCP server with stdio communication

Requirements

• Node.js: 18+ (for npx)
• Python: 3.8+ (auto-detected)
• Internet Connection: Required for initial package download

Troubleshooting

"Python interpreter not found"

• Ensure Python 3.8+ is installed and in your PATH
• Try: python --version or python3 --version

"Failed to install OHM MCP Python package"

• Ensure pip is available: python -m pip --version
• Check internet connection
• Try manual installation: pip install ohm-mcp

Server won't start

• Check that port 3000+ isn't blocked (if using alternative configs)
• Ensure no firewall blocks Python execution
