How do I govern agent steps from AI agents in a AI platforms and model providers environment?

Route agent steps through Kastra. The Kastra proxy or SDK intercepts each step before it executes, evaluates ABAC policy against the request attributes, environment, principal identity, and risk signals, and returns an allow, deny, redact, or human-approval decision. AI platforms and model providers customers map controls directly to EU AI Act, NIST AI RMF, SOC 2.
