plugin-scanner
Scan AI agent skills, plugins, MCP servers, and agent tooling for prompt injection, unsafe commands, secret exposure, and supply-chain risks before installing or trusting them. Use when evaluating agent ecosystem content before installation, publication, or use. Trigger with "scan this skill", "check this MCP server", "audit this agent plugin", or "verify this AI tool".

# Plugin Scanner
## Overview
Use HOL's local `plugin-scanner` when a user asks to inspect an AI agent skill, plugin, MCP server, agent package, or repository before installation or use. The scanner is shipped by the open-source `plugin-scanner` Python distribution. It is built from the same HOL Guard source repository, but it is intentionally packaged separately from the `hol-guard` runtime CLI.
Scanning runs locally and does not require Guard Cloud. Treat scanner findings as evidence about the covered checks, not as a guarantee that a target is safe.
## Prerequisites
- A local path or repository the user has chosen to inspect.
- `pipx` only when `plugin-scanner` is not already installed and the user approves installation.
- Do not execute the target repository, its install scripts, package lifecycle hooks, or arbitrary shell commands to prepare a scan.
- Never read `.env` files, credential stores, private keys, or unrelated user secrets.
