Docs AI & MCP Safety model

Safety model

The useful question about an agent with access to a business is not what it can do — it is what it cannot do, and how that is guaranteed.

Money is never exposed

There is no refund tool, no mark-as-paid, no payout, no capture, no plan-billing and no payment-provider configuration. Not gated — absent. An agent cannot move money because the capability does not exist in the surface.

This is enforced by test, not by policy. The test suite asserts that no registered tool name matches refund, mark_paid, payout, charge, capture, settle, plan_billing, provider, mfa or domain. Adding one fails the build.

Layered refusal

Each layer is independent, so no single mistake opens the door:

Reversibility informs the gating

Order actions sit behind their own gate because they are customer-facing and mostly irreversible — a cancelled booking has already emailed someone. Draft content is ungated because a bad draft costs a click to discard.

What it means for you

You can hand an agent the read surface with very little thought. Enabling commerce or operations is a real decision about a real business, and the docs treat it that way.
