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

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

## Why renameValue is rated Medium

Renaming a value is a reversible modification operation that changes metadata/configuration without deleting underlying data. This is a Write operation rather than Destructive (which would be irreversible deletion). Severity is medium because misconfiguration of proxy rules could impact network traffic handling, but the change is reversible and does not cause data loss or financial impact.

From the tool's own definition: "Tool name 'renameValue' and description '重命名值' (rename value) indicate modification of existing data. The sibling tools include 'createValue', 'deleteValue', and other data manipulation operations, confirming this is part of a proxy configuration system where…"

## Use case

AI agents use renameValue 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": {
    "renameValue": {
      "limits": [
        {
          "counter": "renamevalue_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
