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.
Pros
- Extremely low latency (<1 ms) for real-time authorization
- Supports multiple AI tools and SDKs through a unified control plane
- Enhances security by preventing unauthorized actions and data leaks
- Easy to integrate into existing AI workflows and architectures
- Enforces policies before actions are executed, reducing risk
Cons
- Limited public information on pricing and deployment scale
- Potential complexity in managing policies for large-scale deployments
- Requires integration effort for existing AI systems
Best for
- • Preventing unauthorized use of proprietary AI models in enterprise settings
- • Mitigating prompt injection attacks in sensitive AI applications
- • Controlling access to external tools and APIs via AI agents
- • Ensuring compliance with data privacy regulations during AI interactions
Pricing: Details are not explicitly provided, but likely follows a SaaS subscription model with tiered plans based on usage, number of agents, or enterprise features. A free trial or freemium tier may be available for initial testing.
