Approve what matters. Automate the rest.

Critical MCP actions land in the Outbox. You decide which tools need human approval—and which may run without interrupting the flow.

How actions move through Ironbrain

Every connected agent hits one MCP endpoint. Your HITL policy decides: hold in the Outbox, or run on the auto path.

Clients — Cursor, Claude, and other MCP clients
Gate — Secrets stay server-side; the policy cascade applies
Split — RequireHitl goes to the Outbox; AllowAlways reaches your tools

Real controls, not a chat prompt

The Outbox mirrors what Ironbrain already ships: typed actions, editable payloads, before/after diffs, Approve / Edit / Reject, and a hard floor for external sends.

You set the approval policy

Every action has an HITL mode. It starts from a default and can be overridden for your organization and in your personal settings. Critical tools wait in the Outbox; the rest stay automatic.
