Security Report

5.6
Moderate5.6Moderate Risk

Scherlok is a read-only data-quality monitor whose MCP server resolves credentials server-side, exposes no arbitrary-SQL tool, and bounds output sizes, which is a sound security model. The visible code shows no exfiltration, obfuscation, or hardcoded secrets; the only notable permissions are database access, local SQLite profile storage, and optional webhook/Slack network calls that match its alerting purpose. The scan was truncated, so the remaining connector and alerter code was not fully reviewed. Supply chain analysis found 12 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
