Governs what AI agents are allowed to do.

Deny by default

Every tool call hits the policy engine before it reaches the MCP server. No implicit allows. No fallback to open.

Session governance

Budgets, behavioral bounds, drift detection. Agents stay within the scope they were given.

Audit trail

Every authorization decision logged with PII automatically redacted. Full forensic replay of any session.
