Remove item from user
AI agents call remove_from_cart to permanently remove resources in FakeStore MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing an item from a cart deletes that cart entry. While not catastrophic (carts can potentially be re-populated), the action is not easily reversible without re-adding the item manually, making it closer to Destructive than Write.
From the tool's definition 'remove_from_cart' - removing an item from a cart is a deletion action; 'Remove item from user' confirms removal semantics
Attacks that exploit this kind of access
Remove item from user. It is categorised as a Destructive tool in the FakeStore MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the FakeStore MCP server in PolicyLayer and add a rule for remove_from_cart: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches FakeStore MCP. Nothing to install.
remove_from_cart is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the remove_from_cart rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for remove_from_cart. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
remove_from_cart is provided by the FakeStore MCP server (mithgroth/fakestore-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
