WHAT IT DOES

What set_rack_visible_macros does on Livepilot

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

RISK

Why set_rack_visible_macros is rated Medium

This tool creates or modifies data reversibly within Ableton Live's session state. Setting visible_macro_count changes which macro controls are displayed on the rack interface, but this change is not destructive (can be undone/reverted) and does not delete data. It is not a Read operation because it has side effects (reconfigures the UI/state).

From the tool's definition 'Set the Rack's visible_macro_count directly' — modifies a configuration property of a Rack object in Ableton Live. The tool changes a rack parameter (visible_macro_count) from its current state to a new value (1-16).

RECOMMENDED RULE

The rule that runs set_rack_visible_macros safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Livepilot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_rack_visible_macros, this is the rule to start with:

set_rack_visible_macros Rate-limited

set_rack_visible_macros 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.
