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

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

## Why build_song_brain is rated High

The tool name indicates an action ('build') that constructs or initializes something ('song_brain'), consistent with Execute-category tools that trigger operations whose effects depend on runtime arguments. While the empty description reduces certainty, the context of an Ableton Live copilot with 91 production tools suggests this performs an operation beyond simple data retrieval.

From the tool's own definition: "Tool name 'build_song_brain' suggests construction or initialization of a complex state object within Ableton Live."

## Use case

AI agents invoke build_song_brain to trigger actions in Livepilot. 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 Livepilot:

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