copy_clip · Ableton MCP: Risk & Policy

WHAT IT DOES

What copy_clip does on AbletonMCP

AI agents use copy_clip 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 copy_clip needs a policy

The copy operation is reversible and creates new data without destroying existing data, fitting the Write category. Severity is medium because misuse could clutter sessions with unwanted duplicates and require manual cleanup, but the effects are non-destructive.

From the tool's definition Tool is named 'copy_clip' with an empty description. Within the context of Ableton Live, a clip copy operation creates a duplicate of a clip (reversible write operation).

copy_clip Rate-limited

copy_clip 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.
