Get a hierarchical tree of browser categories from Ableton. Parameters: - category_type: Type of categories to get ('all', 'instruments', 'sounds', 'drums', 'audio_effects', 'midi_effects')
AI agents call get_browser_tree to retrieve information from Ableton MCP Extended without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organizational/structural information from Ableton Live's browser without any side effects. It is a pure query operation that returns hierarchical data. No data is created, modified, deleted, or executed. Even if an AI agent misuses this tool by requesting all categories repeatedly, the impact is limited to unnecessary read operations with no blast radius to user data or system state.
From the tool's definition Tool name 'get_browser_tree' and description 'Get a hierarchical tree of browser categories' indicate data retrieval with no modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ableton MCP Extended, and nothing reaches the server without passing your rules. This is the rule we recommend for get_browser_tree:
{
"version": "1",
"default": "deny",
"tools": {
"get_browser_tree": {}
}
}get_browser_tree is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
