THE RISK

Critical Risk

Why fw_delete_playlist needs a policy

This tool irreversibly deletes data (a playlist) with no undo capability. While the scope is limited to a single playlist rather than system-wide data, the permanent and irreversible nature of the deletion places it in the Destructive category rather than Write. High severity reflects the blast radius if an AI agent deletes important playlists without proper user intent verification.

From the tool's definition Tool description explicitly states 'Permanently delete an entire playlist' and 'is irreversible'. The requirement for 'confirm:true' parameter acknowledges the destructive nature.

POLICY

How to control fw_delete_playlist

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 fw_delete_playlist:

policy.json

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

fw_delete_playlist 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.
