What happens if an agent pulls down a poisoned package or executes a malicious tool?\n\nTo try and solve this for myself, I built W.H.Agent (White Hat Agent). It’s an open-source CLI and sandboxing tool designed to act as a pre-execution and runtime defense for AI agents.\n\nTo be completely honest, it’s still very much a work in progress (the OS-native sandboxing is currently macOS-only, for example), and I’m sure there are edge cases I haven't even thought of yet. But I decided to open-source it today because I genuinely want to see if this approach brings value to other developers.\n\nA few things it currently does:\n\nI figured the best way to learn and improve it is to put it out there. If you have a few minutes, I would be incredibly grateful if you checked it out or gave it a quick roast. Is this something you would use in your workflow?\n\nThanks so much for your time, and I'm looking forward to any feedback (the good, the bad, and the ugly)!", "url": "https://wpnews.pro/news/w-h-agent-an-ai-antivirus-and-sandbox", "canonical_source": "https://dev.to/rishit_agni/whagent-an-ai-antivirus-and-sandbox-2jpd", "published_at": "2026-06-25 21:17:27+00:00", "updated_at": "2026-06-25 21:43:12.198782+00:00", "lang": "en", "topics": ["ai-agents", "ai-safety", "developer-tools"], "entities": ["W.H.Agent", "White Hat Agent", "GitHub", "Cursor", "Claude Desktop", "MCP"], "alternates": {"html": "https://wpnews.pro/news/w-h-agent-an-ai-antivirus-and-sandbox", "markdown": "https://wpnews.pro/news/w-h-agent-an-ai-antivirus-and-sandbox.md", "text": "https://wpnews.pro/news/w-h-agent-an-ai-antivirus-and-sandbox.txt", "jsonld": "https://wpnews.pro/news/w-h-agent-an-ai-antivirus-and-sandbox.jsonld"}}
