THE RISK

Critical Risk

Why delete_applicant needs a policy

This tool meets the Destructive category because it deletes data that cannot be undone after the 30-day retention period expires. Even though soft-delete allows temporary recovery, the primary action is removal of applicant records, which in an identity verification/payment protocol context (AP2 - Agent-to-Agent Payment Protocol) represents sensitive personal or verification data.

From the tool's definition The tool performs a 'Soft-delete' operation on an applicant record. While technically recoverable within a 30-day window, it removes data from active use and permanently deletes it after 30 days.

POLICY

How to control delete_applicant

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_applicant:

policy.json

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

delete_applicant 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.
