What studio_delete does on Notebooklm

AI agents call studio_delete to permanently remove resources in Notebooklm — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Why studio_delete needs a policy

The tool performs an irreversible deletion operation on a studio artifact within NotebookLM. This matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While the blast radius is limited to a single artifact rather than bulk data, deletion of user-created content (such as generated flashcards, mind maps, infographics, or data tables) represents a…

How to control studio_delete

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

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "studio_delete"
  ]
}

studio_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

  1. Create a free account and register Notebooklm — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
