删除坚果云中的文件或目录（谨慎使用！）
AI agents call delete_file to permanently remove resources in Nutstore — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes files or directories from cloud storage. Deletion of cloud data is typically unrecoverable without a backup, making this Destructive with critical severity given the potential blast radius of losing important user data.
From the tool's definition 删除坚果云中的文件或目录（谨慎使用！）— 'delete' in the tool name and description explicitly states it deletes files or directories in Nutstore cloud storage, with a warning to use with caution
Attacks that exploit this kind of access
删除坚果云中的文件或目录（谨慎使用！）. It is categorised as a Destructive tool in the Nutstore MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Nutstore MCP server in PolicyLayer and add a rule for delete_file: 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 Nutstore. Nothing to install.
delete_file 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_file 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_file. 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.
delete_file is provided by the Nutstore MCP server (silverze/nutstore-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_file is one line of Nutstore's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
