Security Report

7.7
Moderate7.7Low Risk

PCRZERO is a well-architected MCP server with strong security discipline. Authentication is properly scoped to the paid `issue_receipt` tool, credentials are never logged or exposed in results, and the codebase demonstrates careful handling of sensitive data through redaction mechanisms and offline verification paths. A comprehensive security test suite (A1–A13) validates key invariants. Minor code quality findings around broad error handling do not materially impact the security posture. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
