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

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

## Why get_language_metrics is rated Low

The name strongly implies a read-only operation that retrieves or queries metrics data without side effects. 'Get' and 'metrics' are typical query patterns. No write, delete, execute, or financial operations are indicated by the name alone. Lower confidence due to missing description, but the naming pattern is consistent with data retrieval.

From the tool's own definition: "Tool name 'get_language_metrics' suggests retrieval of language-related metrics. Description is empty, limiting direct evidence."

## Use case

AI agents call get_language_metrics to retrieve information from AWS 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 AWS:

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