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

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

## Why renameValueGroup is rated Medium

This tool modifies metadata (group names) within the Whistle proxy system but does not delete data or execute arbitrary code. Renaming is a reversible Write operation. Severity is medium because renaming groups could disrupt proxy rule logic if done incorrectly, affecting network traffic handling, but the impact is typically recoverable by renaming back or updating references.

From the tool's own definition: "Tool name 'renameValueGroup' and description '重命名值分组' (rename value group) indicates modification of existing data structure. The sibling tools show this is part of a proxy management system where groups organize values used in proxy rules."

## Use case

AI agents use renameValueGroup to create or update resources in Whistle, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Whistle environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Whistle:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "renameValueGroup": {
      "limits": [
        {
          "counter": "renamevaluegroup_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
