THE RISK

Why cancel_order needs a policy

Cancelling an order in an AFIP (Argentine tax authority) electronic invoicing context is a destructive action that modifies the state of a transaction record irreversibly. While refunds may be processed, the cancellation itself cannot be un-cancelled and represents a permanent change to order status.

From the tool's definition Tool name 'cancel_order' with description 'Cancel an order, optionally restocking and refunding' indicates irreversible termination of a commercial transaction.

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

POLICY

How to control cancel_order

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 cancel_order:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "cancel_order"
  ]
}

cancel_order disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
