How do I govern tool invocations from AI agents in a government and public sector 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. Government and public sector customers map controls directly to FedRAMP, FISMA, CJIS, IL5.
