删除文件夹
AI agents call delete_folder 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.
This tool performs a destructive action by deleting a folder, which is an irreversible operation that results in data loss. Even if the folder is empty, the deletion cannot be reversed without external backup/recovery mechanisms. This is classified as Destructive rather than Write because deletion is fundamentally irreversible, fitting the schema's definition of actions that 'cannot be undone'.
From the tool's definition delete_folder: irreversibly removes a folder (and likely its contents) from Xiaomi Cloud Notes. The operation cannot be undone.
Attacks that exploit this kind of access
删除文件夹. It is categorised as a Destructive tool in the Mi Note MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mi Note MCP Server MCP server in PolicyLayer and add a rule for delete_folder: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mi Note MCP Server. Nothing to install.
delete_folder is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_folder 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_folder. 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.
