Why delete_bounce needs a policy

This tool permanently removes data (a bounced address entry) from a suppression list without the ability to undo the action. While the use case is legitimate (after confirming the issue is resolved), the underlying operation is destructive—it irreversibly deletes a record.

From the tool's definition Tool name contains 'delete'; description explicitly states 'Remove a bounced address' via DELETE method, indicating irreversible removal from the bounce suppression list.

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

How to control delete_bounce

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_bounce:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_bounce"
  ]
}

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

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