WHAT IT DOES

What list_folders does on Tencent Cloud COS MCP Server

AI agents call list_folders to retrieve information from Tencent Cloud COS MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_folders is rated Low

This tool performs a query/list operation on cloud storage metadata. It retrieves information about folders and files but does not create, modify, delete, or execute any code. The operation is non-destructive and has no side effects beyond data retrieval. It falls squarely into the Read category with low severity since listing storage contents carries minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'list_folders' and description '列出COS中的文件夹和文件' (list folders and files in COS) indicates a read-only operation that retrieves and enumerates storage objects without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_folders safely

list_folders Allowed

list_folders is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_folders": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tencent Cloud COS MCP Server, apply this rule, and every list_folders call is checked against it from then on.
