WHAT IT DOES

What quantize_clip does on Ableton Mcp Lofifren

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

WHY IT NEEDS A POLICY

Why quantize_clip needs a policy

Quantizing adjusts note/audio timing to snap to a grid, which modifies clip properties but is reversible (can undo or re-quantize). This fits Write category rather than Destructive since the original data is not irreversibly deleted. The tool description is empty, reducing confidence slightly, but sibling tools and the 'clip' parameter indicate this operates on Ableton Live arrangement data.

From the tool's definition Tool name 'quantize_clip' indicates modification of audio/MIDI clip timing. The server context shows tools that create, add, and modify arrangement elements (add_chord_progression, add_notes_to_clip, add_drum_pattern).
