## Example call (MCP tools/call, JSON-RPC 2.0)

  "jsonrpc": "2.0",

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Tencent Cloud COS MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_folder"
  ]
}
```
