Security Report

4.8

Use Caution4.8High Risk

vmd-hydrate-mcp is a well-engineered MCP server for molecular dynamics analysis with thoughtful security design. Path allowlisting and Tcl command filtering prevent common attack vectors. The stateful VMD session uses token-gated loopback communication with proper timeout handling. No hardcoded secrets, malicious patterns, or dangerous credential handling detected. Minor code quality observations around broad exception handling and input validation do not materially impact the security posture. Supply chain analysis found 5 known vulnerabilities in dependencies (2 critical, 3 high severity). Package verification found 1 issue.
