Permissions & Policy Enforcement for Tool Calls
Permissions & Policy Enforcement for Tool Calls
The most common security failure
Teams validate user permissions in the UI, but forget that the agent can call APIs directly. Always enforce permissions at the tool boundary.
Scopes and least privilege
Give the agent only what it needs. Example: allow “createDraftEmail” but not “sendEmail”.
Policy engine integration
Integrate tools with policy checks (RBAC/ABAC). Tools should reject actions outside scope and return structured errors the agent can interpret.
Auditability
Log: who initiated the action, what was requested, what was executed, and what data was accessed.
