删除指定 ID 的笔记
AI agents call delete_note to permanently remove resources in Mi Note MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a note is an irreversible operation that cannot be easily recovered. While the blast radius is scoped to individual notes (not system-wide), the permanent loss of user data represents a high-severity risk if triggered by an AI agent without proper authorization or safeguards. The operation is unambiguous and unrecoverable, placing it strictly in the Destructive category rather than Write.
From the tool's definition Tool name 'delete_note' and description '删除指定 ID 的笔记' (delete note with specified ID) explicitly performs irreversible deletion of data.

Yes. Add a rate_limit block to the delete_note 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 delete_note. 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.
