Why request_return needs a policy

Requesting a return or refund directly triggers a financial obligation or reversal of a financial transaction. This falls under the Financial category as it commits to reversing payment or goods in exchange for money back. The blast radius is high since an AI agent could mistakenly initiate refund requests on legitimate orders, causing financial loss.

From the tool's definition "Request a return or refund for a delivered order" — initiates a financial refund/return process

Documented attack patterns abuse exactly the kind of access request_return gives an agent:

POLICY

How to control request_return

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

policy.json

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

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