Why delete-inbox-notification needs a policy

This tool permanently removes an inbox notification, which cannot be undone. While the blast radius is limited to a single notification record (rather than bulk data), the destructive nature of deletion places it in the Destructive category rather than Write.

From the tool's definition Tool is explicitly named 'delete-inbox-notification' with description 'Delete a Liveblocks inbox notification'. The verb 'delete' combined with the action of removing a notification record represents an irreversible deletion operation.

POLICY

How to control delete-inbox-notification

PolicyLayer is an MCP gateway — it sits between your AI agents and Liveblocks, and nothing reaches the server without passing your rules. This is the rule we recommend for delete-inbox-notification:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-inbox-notification"
  ]
}

delete-inbox-notification 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 Liveblocks — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
