THE RISK

Why clear_cart needs a policy

Clearing a cart removes all items at once with no indication of reversibility. This is a bulk destructive action on user cart data. While it doesn't delete permanent records or financial transactions, it irreversibly wipes the cart state, warranting a Destructive classification with medium severity given the blast radius is limited to the cart contents.

From the tool's definition 'Remove all items from the cart' — clears all cart contents irreversibly in a single operation

Risk signalsBulk/mass operation — affects multiple targets

POLICY

How to control clear_cart

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 clear_cart:

policy.json

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

clear_cart 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.
