duplicate_track · Ableton MCP: Risk & Policy

WHAT IT DOES

What duplicate_track does on AbletonMCP

AI agents use duplicate_track to create or update resources in AbletonMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AbletonMCP environment.

WHY IT NEEDS A POLICY

Why duplicate_track needs a policy

Duplicating a track creates new data (a copied track object) in the Ableton session, which is reversible via undo or manual deletion. This is a Write operation, not Execute (which would require code execution), not Destructive (duplication is undoable), and not Financial.

From the tool's definition Tool name 'duplicate_track' indicates creation of a new track by copying an existing one. This aligns with sibling Write tools like 'create_audio_track' and 'create_midi_track' which create new track objects.

duplicate_track Rate-limited

duplicate_track 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.
