Read-only list of root categories exposed by the Ableton Live Browser. Use before loading instruments, effects, presets, or samples by browser path; returns available=false with a reason when browser access is unavailable or headless.
AI agents call browser_get_categories to retrieve information from Ableton Mind without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves category metadata from Ableton Live's browser without creating, modifying, executing operations, or deleting data. The explicit 'read-only' designation and lack of any side effects make it a Read category tool with low severity—an AI agent cannot misuse it to cause material harm to user data or sessions.
From the tool's definition Tool description explicitly states 'Read-only list' and 'returns available' status; the name 'browser_get_categories' indicates a retrieval operation with no modification capability.
