Show HN: Guardio – control your AI Agent

https://github.com/radoslaw-sz/guardio
1•radoslaw-sz•1h ago
I always struggle with the guarantee that my AI agent won't do anything that could break my system. An AI agent’s behavior is never 100% guaranteed — there is always a small chance that it might send tons of emails, accidentally delete a file, or cause other unintended side effects.

Guardio solves this issue. You put a proxy in front of all your AI agents and create policies that the agents cannot break. You can forbid sending certain parameters, rate-limit access, or simply break down your AI system into smaller parts so your agents only do exactly what you ask them to do.
