Why voice_clone needs a policy

The tool name 'voice_clone' on an Ableton Live control server suggests it may clone or duplicate a voice/instrument/audio source, possibly related to the sibling tool 'create_voice_from_preview'. Without a description, the exact behavior is unclear. It could be a Write operation (creating a new voice clone), but confidence is low due to missing description.

From the tool's definition Tool name is 'voice_clone' but description is empty/uninformative. Cannot determine exact behavior from name alone.

POLICY

How to control voice_clone

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "voice_clone": {
      "limits": [
        {
          "counter": "voice_clone_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

voice_clone gets a rate cap, and everything else on the server is denied unless you say otherwise.

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