About

Security Report

4.2
Use Caution4.2High Risk

ssh-session-mcp is a well-structured SSH PTY session manager with appropriate authentication handling and reasonable permissions for its purpose. Security is generally strong with input validation, policy-based command filtering, and user-aware access controls. However, some code quality concerns around error handling, broad exception catches, and potential sensitive data exposure in logs warrant attention. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
