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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "rename_object",
    "arguments": {}

## Why rename_object is rated Medium

Renaming an object modifies its metadata/path but does not delete data or execute arbitrary code. It is reversible (can be renamed back) and falls clearly under the Write category. Severity is medium because mass renaming of critical objects could cause confusion or operational disruption, but the operation itself is non-destructive.

From the tool's own definition: "Tool name is 'rename_object' and description states it renames objects in COS (Tencent Cloud Object Storage). The Chinese description '重命名COS中的对象' translates to 'rename objects in COS'. Renaming is a reversible modification operation."

## Use case

AI agents use rename_object to create or update resources in Tencent Cloud COS MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tencent Cloud COS MCP Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. 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",
  "tools": {
    "rename_object": {
      "limits": [
        {
          "counter": "rename_object_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
