Runtime authorization for Claude, Cursor, Codex and OpenClaw

Kastra is the runtime authorization layer for AI agents. It decides what agents can and cannot do before actions execute, enforcing policies with sub-1 ms latency across tools, prompts, inputs, and outputs. Use one control plane to govern agents and policies across Claude Code, Cursor, Codex, OpenClaw, the Anthropic SDK, the OpenAI SDK, and more. Prevent unauthorized tool use, prompt injection, and exposure of sensitive data before they become incidents. Trust the rules, not the agents.
Love the recon scan to know all the unexpected/dangerous things Claude Code has done in the past. Some things I already knew but it caught some others I didn't know about it. And with automatic policy generation I don't need to worry about it messing up again!

@churds Exactly, Richard, this gives you a baseline of policies that adjust to your coding behavior first. Then, once you have this baseline, you can build new daily policies on top of them to continue reducing risks you learn along the way. Some Recon scans from our customers show many important high-risk actions they were not aware of; some thought they were protected with their existing frameworks, and the reality was different.
Governing agents before they act instead of auditing after the fact is the shift I've been hoping for.

I like that this doesn't ask me to trust the agent's judgment at all, it just checks the action against a rule before anything happens. That's the right mental model. Most of the "AI safety" tooling I've evaluated this year still leans on the model behaving well, which never sat right with me.

@thomas_jack3 Very accurate! We learned this by testing the product with some of the top enterprises pushing AI products into production. We realized autonomous AI products required a new infra layer and we built Kastra to solve the trust problem in a scalable way.
The "zero implicit trust" framing is really nice. Most agent safety thinking stops at the model level. Most actual work is on how to set actual programmatic hard walls
well done team:)

I use Kastra everyday to discover the risks while coding and it’s very useful.
Highly recommend 👍🏻

@carlos_campos93 This is great, thank you. We're happy we can bring value to you!
I have been testing kastra with my team and even though I’m not very technical it’s very simple to use and it has helped us a lot while building our product.

@paula_jimenez4 Kastra is great for new builders learning how to code; it teaches them the risks and helps them understand the agentic coding workloads better by being able to evaluate all the actions, risks, and decisions at runtime.

This is the kind of infrastructure that won't get the loudest headlines, but could become a core part of every serious AI stack. As agents gain more autonomy, authorization becomes just as important as intelligence. Congrats to the entire team and wishing you an amazing launch
