THE RISK

Why generate_music needs a policy

This tool triggers an external API call to ElevenLabs to generate music content. It executes an operation on an external service whose effects depend on the provided text prompt argument. While it produces creative content rather than executing system commands, it invokes an external paid API service (ElevenLabs), which may have cost implications and produce content based on potentially arbitrary prompts.

POLICY

How to control generate_music

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:

policy.json

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

generate_music 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.
