Fetch full metadata for one notebook by id. Use to verify what
AI agents call get_notebook to retrieve information from Notebooklm without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation to retrieve and display notebook metadata. It does not modify, delete, execute, or create any resources, nor does it perform financial transactions. The incomplete description ('Use to verify what') does not alter this assessment.
From the tool's definition Tool name 'get_notebook' and description 'Fetch full metadata for one notebook by id' indicate a retrieval operation with no side effects.

Yes. Add a rate_limit block to the get_notebook rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_notebook. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
