OUR ASSESSMENT

Strengths
  • Snyk official maintenance.
  • 2,366 GitHub stars.
  • 81 commits on main in the last 30 days.
  • Apache-2.0 license.
  • Purpose-built for MCP and agent skill security.
  • SARIF export integrates with standard CI security tooling.
Weaknesses
  • Snyk account required for full feature set; some scans need API access.
  • Findings are heuristic; manual security review still recommended for high-stakes deployments.
  • Coverage depends on Snyk's vulnerability database update cadence.
Security Notes

SNYK_TOKEN is account-scoped. Use a CI service-account token rather than personal credentials. Scan results may include sensitive context (file paths, environment variables); restrict access to scan reports to the security team.

Best For

Security teams reviewing third-party MCP servers before mounting them; CI flows that scan agent skills before deployment; auditors validating that agent stacks meet security policy.

SOURCES & VERIFICATION

We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
