WHAT IT DOES

What delete_folder does on Tencent Cloud COS MCP Server

AI agents call delete_folder to permanently remove resources in Tencent Cloud COS MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_folder is rated Critical

This tool irreversibly deletes a folder and all its contents in Tencent Cloud Object Storage. Folder deletion cannot be undone and results in permanent data loss. This is a destructive operation with significant blast radius if misused by an AI agent—an agent could accidentally delete critical business data, backups, or entire project directories.

From the tool's definition Tool name is 'delete_folder' and description states '删除COS中的文件夹' (delete folder in COS). The sibling tool 'delete_object' and 'delete_multiple' on this same server confirm the deletion capability pattern.

RECOMMENDED RULE

The rule that runs delete_folder safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tencent Cloud COS MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_folder, this is the rule to start with:

delete_folder Hidden

delete_folder is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
