Why generate_music_from_plan needs a policy

This tool executes an Apple Shortcut that generates music content based on a plan. It triggers an external operation whose effects depend on arguments (the composition plan). It doesn't simply read or write structured data — it runs a process to produce generated output. Severity is medium since misuse could generate unwanted content or consume system resources, but blast radius is relatively contained.

From the tool's definition 'Generate music from a composition plan' — triggers an external operation (music generation) via Apple Shortcuts CLI

POLICY

How to control generate_music_from_plan

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_music_from_plan": {
      "limits": [
        {
          "counter": "generate_music_from_plan_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_music_from_plan stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Apple Shortcuts — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
