Delete a OneNote notebook by its ID
AI agents call deleteNotebook to permanently remove resources in OneNoteMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call deleteNotebook doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from OneNoteMCP is gone — there is no undo for destructive operations.

Yes. Add a rate_limit block to the deleteNotebook 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 deleteNotebook. 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.
deleteNotebook is provided by the OneNote MCP server (swax/onenotemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
