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

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

## Why get_chroma is rated Low

This tool queries and returns computed audio feature data (chroma/pitch class energy) for analysis purposes. It reads real-time audio state from Ableton Live but does not create, modify, delete, or execute arbitrary operations. No side effects or irreversible changes are possible. Severity is low because misuse merely returns analysis data that cannot cause harm to the music project or external systems.

From the tool's own definition: "Tool name 'get_chroma' and description 'Get 12 pitch class energies' indicate retrieval of real-time audio analysis data."

## Use case

AI agents call get_chroma to retrieve information from Livepilot 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 Livepilot:

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