Runtime authorization for Claude, Cursor, Codex and OpenClaw
Kastra is an innovative runtime authorization layer designed specifically for AI agents and tools like Claude, Cursor, Codex, and OpenClaw. It acts as a security gatekeeper, determining what actions AI agents can perform before they execute, ensuring compliance with policies and reducing the risk of misuse. With sub-1 millisecond latency, Kastra seamlessly integrates with various SDKs and tools, providing a centralized control plane to manage permissions across multiple AI environments. This makes it ideal for organizations seeking to enforce strict security and operational policies without compromising performance. Its ability to prevent unauthorized tool usage, prompt injections, and data leaks before they occur sets it apart, emphasizing trust in rules rather than the agents themselves. Kastra empowers developers and security teams to maintain control over AI interactions while supporting the agility required for modern AI deployments.
