THE RISK

Critical Risk

Why crow_dismiss_all_notifications needs a policy

Dismissing all notifications is a bulk, irreversible action that permanently removes notification data. While notifications themselves are low-value, the bulk nature and inability to recover dismissed notifications (especially across an AI-powered platform with P2P sharing and multiple integrations) warrants Destructive classification at medium severity.

From the tool's definition 'Dismiss all notifications' — bulk removal of all notifications, optionally filtered, which irreversibly clears notification records

POLICY

How to control crow_dismiss_all_notifications

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

policy.json

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

crow_dismiss_all_notifications 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 Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
