WHAT IT DOES

What commit_preview_variant does on Livepilot

AI agents use commit_preview_variant 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 commit_preview_variant is rated Medium

The word 'commit' implies saving or applying a change (a write operation), and 'preview_variant' suggests it finalizes a previewed version of something in Ableton Live. Without a description, confidence is low, but 'commit' most commonly maps to a Write action. It could potentially be Destructive if it overwrites existing data irreversibly, but that cannot be confirmed from the name alone.

From the tool's definition Tool name 'commit_preview_variant' suggests finalizing/saving a previewed variant, implying a write/commit operation. Description is empty.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

commit_preview_variant Rate-limited

commit_preview_variant 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.
