THE RISK

Why checkout_ready needs a policy

This tool prepares a basket for financial transaction (food order payment). While it may not finalize the payment itself, it is a direct precursor to committing a financial obligation and operates within a payment context. Misuse could lead to unintended purchases, placing it in the Financial category with high severity.

From the tool's definition 'Get basket ready for checkout with payment context. Call this before placing an order.' - directly initiates the checkout/payment flow for food orders

POLICY

How to control checkout_ready

PolicyLayer is an MCP gateway — it sits between your AI agents and Food402, and nothing reaches the server without passing your rules. This is the rule we recommend for checkout_ready:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "checkout_ready": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to checkout_ready is blocked until a human approves it. The rest of the server keeps working.

Create a free account and register Food402 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
