Why create_full_arrangement needs a policy

This tool generates and creates new MIDI files, which is a write operation that creates data artifacts. The action is reversible (files can be deleted or re-generated), so it does not qualify as Destructive. There are no side effects beyond file creation, no code execution or external operations triggered by arguments, and no financial implications.

From the tool's definition Tool name uses 'create' and description states 'Generate a complete arrangement' — creates new MIDI files (music data) that are stored/exported, constituting data creation.

How to control create_full_arrangement

PolicyLayer is an MCP gateway — it sits between your AI agents and DAW MIDI Generator MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_full_arrangement:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_full_arrangement": {
      "limits": [
        {
          "counter": "create_full_arrangement_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_full_arrangement stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
