Security Report

4.8

Use Caution4.8High Risk

AntoSkills is a well-designed MCP server for discovering, vetting, and installing Agent Skills with strong security guardrails. The codebase demonstrates good security practices including allow-listing (only indexed skills can be installed), pinned reproducible installs with integrity verification, mandatory safety scanning with acknowledgement gates for high-risk skills, and proper credential handling via environment variables. The code is clean with comprehensive test coverage including security invariant testing. Minor code quality observations around broad exception handling in a few places do not materially affect the security posture. Supply chain analysis found 11 known vulnerabilities in dependencies (2 critical, 3 high severity). Package verification found 1 issue.
