🔒 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
