  "jsonrpc": "2.0",

## Why set_track_volume is rated Medium

This tool creates or modifies data reversibly—the volume can be adjusted up or down without permanent loss or destruction. It affects audio mixing state but does not execute external code, delete data, or move money. The moderate severity reflects that incorrect volume settings in a live DAW could cause audio issues or disrupt a performance, but the effect is fully reversible and limited to a single parameter.

From the tool's own definition: "'Set a track's volume (0.0-1.0)' describes modifying audio parameters; this is a reversible state change to a track's mixer properties."

## Use case

AI agents use set_track_volume 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.
