Run HOL Guard scanner and guard operations via `uv run hol-guard`. Use when the user asks to scan plugins/MCP/skills for security, quality, or ecosystem compliance, or when they ask to run guard detect/install/protect workflows for local AI harnesses.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HOL Guard HOL Guard is an AI Antivirus scanner that checks plugins, MCP servers, skills, and local AI harnesses for security, quality, and ecosystem compliance. ## Prerequisites - Always run from the `hol-guard` project root. - Use `uv run hol-guard` to invoke the CLI. Never invoke Python modules directly. - Ensure `uv sync --frozen --extra dev` has been run before invoking. ## Scanner Operations Scan a plugin or skill directory: ``` uv run hol-guard scan <directory> [--format json|text|markdown|sarif] [--profile default|public-marketplace|strict-security] [--fail-on-severity critical|high|medium|low|info|none] ``` Lint rules: ``` uv run hol-guard lint <directory> [--list-rules] [--explain <rule-id>] ``` Verify runtime: ``` uv run hol-guard verify <directory> [--online] ``` List ecosystems: ``` uv run hol-guard --list-ecosystems ``` ## Guard Operations Detect harnesses: ``` uv run hol-guard detect [codex|claude|cursor|gemini|opencode] [--json] ``` Run guard in dry-run mode: ``` uv run hol-guard run <harness> --dry-run --default-action allow --json ``` Check guard status: ``` uv run hol-guard status [--json] ``` ## Common Test Fixtures …

How to install
mdr add hashgraph-online/hol-guard/hol-guard@sha256:6fe65f495bef188eThe line at the top of this page pins the label git:20260608.71a64ac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
