PyPI `hol-guard` and `plugin-scanner` (HTTP 200). `pipx install hol-guard` then `hol-guard init` — no account required for local mode. Covers secret exposure, destructive ops, prompt injection, and supply-chain risks across agents/plugins/skills/MCP. Optional Guard Cloud for team policy is separate from the OSS bar.","theCatch":"Vs SkillSpector / mcp-scanner / destructive-command-guard / AI-Infra-Guard: SkillSpector scans skills pre-install; MCP Scanner audits MCP servers; dcg is a host deny-hook; AI-Infra-Guard is red-team platform — HOL Guard’s catch is runtime local policy/antivirus across agent actions including MCP calls. Policy false positives can stall agents; optional cloud is not required — keep local-first if that is the point.","verdict":"Apache local agent antivirus when you need runtime allow/block on tools and MCP — not skills-only scanners and not MCP-server audit alone.","addedAt":"2026-10-02","featured":false,"domain":"AI Agents","subSpecialty":"Security","subcategory":"Security","tags":["mcp","self-host","local-first","permissive","skills","security","active"],"capabilities":["security","mcp","policy"],"surfaces":["MCP","Self-host"],"ecosystem":["Python","Multi-platform"],"licenseModel":"Apache-2.0","githubStars":933,"starsPerWeek":32,"access":"free","archived":false,"repo":{"createdAt":"2026-03-28","pushedAt":"2026-10-19","license":"Apache-2.0","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/hol-guard","html":"/gems/hol-guard","markdown":"/gems/hol-guard.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
