Security Considerations

WARNING: This server has powerful system control capabilities including:

• Mouse and keyboard control
• Process termination
• Clipboard access
• Screen capture

Only use in trusted environments where you control the MCP client.

Recommended Security Practices

1. Restrict Usage: Only enable when actively needed
2. Review Logs: Monitor all automated actions
3. Sandbox Testing: Test in isolated environments first
4. Access Control: Limit who can access the MCP client
5. Disable PyAutoGUI Failsafe: Server disables failsafe for automation - be cautious

Troubleshooting

Tesseract Not Found

TesseractNotFoundError: tesseract is not installed

Solution: Install Tesseract OCR from https://github.com/UB-Mannheim/tesseract/wiki

Permission Errors

PermissionError: [WinError 5] Access is denied

Solution: Run VS Code or MCP client as Administrator for process control features

Module Not Found

ModuleNotFoundError: No module named 'mcp'

Solution: Reinstall dependencies: pip install -e .

Window Not Found

Window not found: [title]

Solution: Use partial window title matching. Check exact title with list_windows first.
