THE RISK

Critical Risk

Why delete_invoice needs a policy

This tool irreversibly deletes financial invoices, which cannot be undone. Deletion of invoices has severe consequences for financial reconciliation, audit trails, compliance, and accounting. An AI agent misusing this tool could destroy critical financial records and audit records. This is a core Destructive action (irreversible data destruction) in a Financial context (invoices), making it the most severe category.

From the tool's definition "Delete an invoice. Permanently removes the invoice." — the word "Permanently" combined with "Delete" and "removes" indicates irreversible deletion of financial record data.

POLICY

How to control delete_invoice

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_invoice:

policy.json

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

delete_invoice 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.
