Security Report

3.2
Use Caution3.2High Risk

This MCP server implements NYC Local Law 144 bias audit calculations with reasonable core logic. However, it contains a critical data persistence vulnerability: the `_sigil` function logs audit operation details and previous digests to an unencrypted local file without access controls, creating a record of all audited categories and group counts. Additionally, the sigil mechanism itself uses inadequate cryptographic practices (16-char SHA256 prefix, no HMAC, no integrity verification). File permissions are unspecified, and the log file location is world-writable by default. While the audit calculations themselves are sound, these security gaps are inappropriate for legally-required compliance records that may contain sensitive employment data patterns. Supply chain analysis found 6 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.

Tools

  • run_bias_audit(category, groups) — selection rate + impact ratio per group; flags impact ratio < 0.80 (4/5ths rule)
  • generate_ll144_summary(audits, tool_name, audit_date) — the publishable summary + overall compliance
  • check_compliance(...) — the procedural requirements (independent audit, published summary, candidate notice, ≤12 months)
