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

This is the 3rd launch from Agentinel. View more

Hey everyone 👋 When we launched Agentinel, our goal was simple: stop AI coding agents (like Cursor and Claude) from hallucinating and installing malicious `npm` packages on your machine. We built a lightning-fast local firewall, shipped it, and thought we had solved the problem. But we completely overlooked reality. Most of us aren't just writing JavaScript anymore. We're juggling Python scripts and Rust backends in the same project. If an AI agent decided to run `pip install [fake_package]`, our "impenetrable" firewall just let it happen. We were only protecting 33% of the modern stack. In v1.2.0, we just shipped a massive architectural overhaul. Agentinel now intercepts `pip` and `cargo` commands in real time. We had to build custom registry fetchers for `pypi.org` and `crates.io`, and expand our local offline database to handle hundreds of megabytes of Python and Rust vulnerability data—all while keeping interception under 1 millisecond. If you're using AI agents across different languages, you're finally protected across your entire stack. I'm curious—for those of you using AI coding assistants, which ecosystem (JS, Python, Rust, Go) do you see the AI hallucinate packages for the most?

Am I overthinking AI security, or is this actually useful? Need your feedback.

Hey everyone

I've been building a zero-trust local firewall for AI coding agents (like Cursor, Claude Code, etc.).

The problem I m trying to solve is that LLMs constantly hallucinate package names. Bad actors are starting to register those fake packages with malicious code (slopsquatting). So if your AI agent autonomously runs `npm install` or `pip install` on a hallucinated package, your machine gets compromised instantly.

I just spent weeks updating my tool (Agentinel) to natively intercept terminal commands across JS, Python, and Rust in under 1 millisecond. It uses a massive offline vulnerability database to block the AI from pulling malware before the shell even executes it.
