WHAT IT DOES

What store_rack_variation does on Livepilot

AI agents use store_rack_variation 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 store_rack_variation is rated Medium

This tool saves/creates a new variation entry with current macro values. It is a reversible write operation (creating a named snapshot) with no destructive, financial, or execution implications. Misuse has minimal blast radius as it only stores a preset variation within Ableton Live.

RECOMMENDED RULE

The rule that runs store_rack_variation 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 store_rack_variation, this is the rule to start with:

store_rack_variation Rate-limited

store_rack_variation 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.
