Agentinel
Stop AI agents from installing malicious packages.
Because your AI loves slopsquatting, Agentinel is a zero-cost, locally-run package guardrail for autonomous AI coding agents (like Claude Code and Cursor). It integrates directly at the hook level to intercept hallucinated and malicious npm packages before they execute, checking them against a 60,000+ threat database in under 2ms
Hey Product Hunt, I am thrilled to launch Agentinel today.
LLMs are incredible coders, but they are genuinely terrible at remembering exact npm package names. They frequently hallucinate packages or fall victim to slopsquatting, where attackers publish malicious packages with names that AIs are known to hallucinate. If you use autonomous agents like Claude Code or Copilot Workspace, your terminal is executing these installs automatically.
Agentinel acts as a security layer that sits between your AI agent and your package manager. It doesn't just scan your repo after the fact; it intercepts the AI's intended command and validates every package before it runs. It executes in under fast using local heuristics and a lightweight offline database, and it is 100% free and open source.
I built this because I wanted the speed of autonomous AI coding without the constant anxiety of what it was installing in the background.
Would love to hear your thoughts, feedback, or any wild AI hallucination stories you've experienced. I will be hanging out in the comments all day to answer questions!
slop guard was getting out of hand on my cursor projects, this hooks right in and flags sketchy packages before they sneak into a build. under 2ms really is no noticeable lag
honestly this is super relevant right now with all the slop attacks going around. one thing though, it would be really helpful if you could add a dry-run mode that logs any blocked package to a file or stdout without actually stopping execution, basically so teams can audit what their agent tried to install over a week before fully enforcing the block
With the rise of vibecoding, the projects and products numbers are exponentially increasing while security vulnerability are going downhill as non-tech users are the most in them. Hoping with Agentinel the security of vibecoded projects will be enhanced and more reliable the product is promising.
Hooked it up to Claude Code and it flagged a sketchy npm package in under a second, way faster than I expected. The local-first approach is a nice touch.
Would love to see support for PyPI in addition to npm since most of my projects mix Python and JS, and the threat landscape is just as real on that side. Could be a huge win for polyglot codebases.
Congrats on launching Agentinel! This looks genuinely exciting — wishing the team a fantastic PH day! 🚀
Finally got around to setting up the hook in Claude Code and it really did block a sketchy package the agent tried to install, whole check was basically instant. Solid little safety net for anyone running agents unsupervised.
Hooked it into Claude Code and watched it actually flag a suspicious package before install. Genuinely impressed how fast the checks run locally without slowing things down.
