SkillGuard MCP

SkillGuard is a security scanner for third-party AI agent-skill files that operates as an MCP server, CLI, library, and GitHub Action. It scans SKILL.md manifests, hooks, and bundled scripts for known attack patterns such as prompt injection, credential harvesting, and cross-skill privilege chaining using ten bundled rule packs. It provides static analysis for supply-chain security in AI agent ecosystems.
