What clear_simpler_slices does on Livepilot
AI agents call clear_simpler_slices 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.
Why clear_simpler_slices is rated Critical
This tool destroys user-created data (manual slice markers) in an audio sampler instrument without the ability to undo through the tool itself. The blast radius is significant for a music producer relying on those slices for their arrangement. While Ableton may have undo history, the tool's explicit purpose is permanent removal, making it Destructive rather than Write.
From the tool's definition "Remove all manual slices from the Simpler" — this action irreversibly deletes slices that a user has manually created in Ableton Live's Simpler instrument. The slices cannot be recovered without manual recreation.
Attacks that exploit this kind of access
The rule that runs clear_simpler_slices 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 clear_simpler_slices, this is the rule to start with:
clear_simpler_slices is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Livepilot, apply this rule, and every clear_simpler_slices call is checked against it from then on.
