clip_fire · Ableton Mind MCP: Risk & Policy

WHAT IT DOES

What clip_fire does on Ableton Mind

AI agents invoke clip_fire to trigger actions in Ableton Mind. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why clip_fire needs a policy

This tool executes an action with side effects in a music production system. While triggering clip playback is not destructive or financial, it does cause the DAW to perform an operation (audio playback initiation) external to the MCP server itself.

From the tool's definition Tool triggers playback of a session clip in Ableton Live ("Trigger a session clip slot", "launch a specific clip in Session view").
