ULTRATHINK Deep Cleanup - Scans entire system for ALL NotebookLM MCP data files across 8 categories. Always runs in deep mode, shows categorized preview before deletion.\n\n

How to control cleanup_data ↓

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

Critical Risk

This tool explicitly deletes data files across 8 categories system-wide. The word 'deletion' and 'cleanup' indicate irreversible destruction of data. The blast radius is critical because it operates on the 'entire system' across ALL data files, meaning misuse could wipe all NotebookLM MCP data irreversibly.

From the tool's definition 'cleanup_data' with description 'Deep Cleanup - Scans entire system for ALL NotebookLM MCP data files across 8 categories... shows categorized preview before deletion'

Risk signalsBulk/mass operation — affects multiple targets

Documented attack patterns abuse exactly the kind of access cleanup_data gives an agent:

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

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

cleanup_data 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 MCP Structured — 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.
