Security Report

3.8

Use Caution3.8High Risk

This MCP server provides autonomous desktop control with comprehensive safety mechanisms in place. The code is well-structured with proper input validation and no malicious patterns detected. However, the inherent nature of full OS control (mouse, keyboard, screen access) combined with lack of authentication represents a significant trust boundary risk — the server operates at user privilege level without any credential-based access control. Users must explicitly trust that Claude will use these capabilities responsibly, as there are no cryptographic or authorization barriers preventing misuse once the server is activated. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
