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

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

## Why getValueList is rated Low

This is a read-only operation that queries and retrieves metadata about values without modifying any state. The description explicitly constrains the response to index and name fields, confirming its purpose is data retrieval with no side effects. No creation, modification, deletion, code execution, or financial impact is possible.

From the tool's own definition: "Tool name 'getValueList' and description indicate it retrieves a list of values with only index and name fields, explicitly avoiding returning data fields to prevent large data volumes."

## Use case

AI agents call getValueList to retrieve information from Whistle without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "getValueList": {}
  }
}
```
