fire_clip · Ableton Live MCP: Risk & Policy

WHAT IT DOES

What fire_clip does on Ableton Live

AI agents invoke fire_clip to trigger actions in Ableton Live. 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 fire_clip needs a policy

This tool executes an action (clip playback) in an external application (Ableton Live) whose consequences depend on which clip is selected or passed as an argument. While not destructive or financial, it is an Execute category action as it triggers operations external to the MCP server.

From the tool's definition Tool name 'fire_clip' with description 'Start playing a clip' indicates triggering an external operation (audio playback) in Ableton Live via OSC control. This is an action that causes an immediate, observable effect in a DAW.
