MOST DANGEROUS TOOLS

High Risk

The most dangerous Notebooklm Codex tools

Execute · Medium notebooklm_generate_audio This tool triggers an external generation operation (audio synthesis) in NotebookLM. Write · Medium notebooklm_source_add This tool modifies notebook state by appending new sources, which is a Write operation (reversible data creation). Write · Medium notebooklm_use This tool changes which notebook is the active context for subsequent operations.

3 of Notebooklm Codex's 9 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Notebooklm Codex

PolicyLayer is an MCP gateway — it sits between your AI agents and Notebooklm Codex, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "notebooklm_source_add": {
    "limits": [
      {
        "counter": "notebooklm_source_add_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "notebooklm_artifact_list": {
    "limits": [
      {
        "counter": "notebooklm_artifact_list_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
