How do I govern tool invocations from AI agents in a retail and e-commerce environment?

Route tool invocations through Kastra. The Kastra proxy or SDK intercepts each tool call 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. Retail and e-commerce customers map controls directly to PCI DSS, GDPR, CCPA.
