Security Scanner for Agent Skills

Install

The skill file stays in the publisher's repository.

Paste the copied command in a terminal. It installs this SKILL.md into that agent.

npx skills add cisco-ai-defense/skill-scanner --skill mcpwn-cve-2026-33032 -a cursor -y

How do I install skill-scanner?: Download evals/test_skills/malicious/mcpwn-cve-2026-33032/SKILL.md from the publisher, or copy the path and open the repository. PlugMCP lists the skill and does not host the file.
Where does skill-scanner live?: The publisher keeps it at https://github.com/cisco-ai-defense/skill-scanner.
Which agents can use skill-scanner?: Claude, Cursor, and Codex can read a SKILL.md you add from the publisher's repository.

Demonstrates MCPwn runaway invocation pattern.
