WHAT IT DOES

What discard_preview_set does on Livepilot

AI agents call discard_preview_set to permanently remove resources in Livepilot, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why discard_preview_set is rated Critical

This tool permanently removes a preview set and all associated variants from the Ableton Live project, with no recovery mechanism. While the blast radius is somewhat limited to preview sets (not the entire production), the operation is irreversible and would cause loss of work. This places it firmly in the Destructive category rather than Write, as discarding cannot be reversed through normal means.

From the tool's definition Tool name 'discard_preview_set' combined with description 'Discard an entire preview set and all its variants' indicates irreversible deletion of data.

RECOMMENDED RULE

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

discard_preview_set Hidden

discard_preview_set is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
