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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "bmr_calculator",
    "arguments": {
      "age": 0,
      "sex": "<sex>",
      "height_cm": 0,
      "weight_kg": 0
    }
  }
}
```

## Why bmr_calculator is rated High

bmr_calculator triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

## Use case

AI agents invoke bmr_calculator to trigger actions in SmartTools. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bmr_calculator": {
      "limits": [
        {
          "counter": "bmr_calculator_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
