Show HN: Policy enforcement for Claude Code, Cursor, and Codex (kastra.ai)

Kastra has unveiled a groundbreaking tool aimed at AI governance, enabling proactive authorization for AI systems like Claude Code, Cursor, and Codex. This innovative infrastructure autonomously checks every user prompt, tool call, and API request against pre-defined policies in under a millisecond, ensuring that only permitted actions are executed. Unlike existing monitoring solutions that react post-action, Kastra provides a preemptive layer of security by intercepting potential risks before they occur, fostering greater control over AI behaviors in various applications, including coding agents and autonomous browsers. This release is particularly significant for the AI/ML community as it tackles some of the core challenges surrounding AI safety and accountability. By integrating features such as identifying each action's identity, evaluating scope, and applying strict guardrails, Kastra enables organizations to maintain stringent compliance measures while empowering users. The system not only validates actions but also logs historical AI behaviors, allowing teams to refine their policies effectively. With a free tier for solo developers, Kastra lowers the barrier for widespread adoption, encouraging responsible AI development and deployment across varying expertise levels.
