Security Report

5.2
Moderate5.2Moderate Risk

This is a well-designed read-only MCP server for VMware ESXi with strong security architecture. The server properly enforces read-only constraints through code design, credential handling via keyring, and intentionally excludes all write operations. Minor code quality issues (broad exception handling, unvalidated user input in some query parameters) and the truncated file prevent a higher score, but these do not pose security risks given the server's read-only nature and appropriate permission scoping. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
