Security Report

6.8

Moderate6.8Moderate Risk

The MCP server is well-designed with strong security fundamentals: credentials never flow through tool arguments (only connection names are accepted), DSN injection is actively prevented, the four tools are properly scoped and read-only, and input validation is comprehensive. SQL injection is mitigated through sqlglot parsing and re-rendering. Minor code quality issues around broad exception handling and logging do not materially impact security posture. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
