THE RISK

Critical Risk

Why delete_subscription needs a policy

This tool permanently deletes data (a webhook subscription record) without reversibility or undo capability. In the context of AP2's authorization and audit framework, removing a subscription could disable critical notification systems that track payment events, dispute resolution, or compliance auditing. This makes it Destructive rather than Write.

From the tool's definition The tool performs 'Delete a webhook subscription by ID' — it irreversibly removes a configured subscription, preventing future webhook notifications and audit trails.

POLICY

How to control delete_subscription

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_subscription:

policy.json

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

delete_subscription 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.
