Why mind_map_delete needs a policy

This tool permanently removes a Mind Map artifact from a notebook. The deletion is irreversible and constitutes data loss. While the blast radius is limited to Mind Maps within NotebookLM (not system-level or cross-service destruction), the action cannot be undone and represents a destructive operation. Severity is high rather than critical because the impact is scoped to a single artifact type within one service.

From the tool's definition Tool name is 'mind_map_delete' with description 'Delete a Mind Map from a notebook'. The verb 'Delete' combined with the action of removing a Mind Map indicates irreversible data destruction.

POLICY

How to control mind_map_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 mind_map_delete:

policy.json

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

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