About
SkillCheck is Repello AI's public scanner for AI agent skills and MCP tools, designed to surface security vulnerabilities before deployment. Upload a skill and get a severity-rated report covering prompt injection paths, unsafe tool behaviors, and data exfiltration risks. It's part of Repello's broader AI security platform (ARTEMIS, ARGUS, MCP Gateway) for teams who need systematic security review of third-party or custom agent tooling.
Security-conscious teams evaluating third-party MCP tools or custom agent skills before production rollout, particularly in regulated environments where prompt injection and data exfiltration risks need documented review.
Pros & Cons
Pros
- check Targeted at the specific risk category of AI skill/MCP tool vulnerabilities — not generic static analysis
- check Public scanner means you can scan community or third-party skills before trusting them in production
- check Severity ratings help prioritize which issues need immediate attention vs. low-risk findings
- check Part of an enterprise security ecosystem (ARTEMIS, ARGUS) for teams needing deeper coverage
- check Free to upload and scan individual skills — no immediate enterprise commitment required
Cons
- close The public skill listing was empty/loading during review — unclear how active the community upload feature is
- close Scan methodology and detection coverage aren't clearly documented publicly; hard to assess false positive/negative rates
- close Prompt injection detection in AI skills is a hard problem; automated scanners will have gaps
- close Primarily useful pre-deployment — doesn't provide runtime monitoring of skills in production
