THE RISK

Critical Risk

Why delete_customer needs a policy

Deleting a customer is an irreversible operation that cannot be undone and has severe consequences: loss of customer records, transaction history, contact information, and potential compliance/audit issues. In a financial payment protocol context (AP2), this impacts both customer data integrity and financial records.

From the tool's definition Tool name 'delete_customer' combined with description 'Delete a customer' indicates irreversible removal of customer data. The verb 'delete' and the broad scope (entire customer entity) confirms destructive intent.

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

POLICY

How to control delete_customer

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_customer:

policy.json

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

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

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
