What is Kastra?

Kastra acts as a vital authorization framework for AI systems, establishing the permissions of agents, models, and tools before they are executed. Situated along the execution path of numerous interactions, including prompts, tool calls, shell commands, database transactions, and API requests, it assesses each action through deterministic, attribute-based policies, making decisions to allow, deny, redact, or escalate in less than a millisecond. Unlike monitoring solutions that merely observe AI activities after they occur, Kastra takes a preemptive stance, blocking unauthorized actions before they can affect any tools, APIs, databases, or production systems. Its extensive control plane encompasses a policy engine, edge decision-making features, multiple integrations, and a tamper-proof evidence vault that securely records each decision for future auditing and replay. Additionally, with the introduction of Kastra Edge, local enforcement capabilities are broadened to developer environments, protecting coding agents like Claude Code, Cursor, and Codex CLI from malicious commands, unauthorized data access, unsafe file changes, and incorrect tool usage. This forward-thinking approach to authorization not only bolsters security but also guarantees compliance and accountability in AI-driven operations, fostering a more trustworthy environment for users. By ensuring that all actions are rigorously vetted, Kastra significantly mitigates potential risks associated with AI technologies.
