Why unlink_items is rated Critical
An AI agent that decides to call unlink_items doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Grabblist is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs unlink_items safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Grabblist, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unlink_items, this is the rule to start with:
unlink_items is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Grabblist, apply this rule, and every unlink_items call is checked against it from then on.
