# fl_list_library A read tool on the FL Studio MCP Server MCP server. Agent View of the PolicyLayer registry record for `fl_list_library`. HTML page: https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-list-library ## Facts - Tool: `fl_list_library` - Server: FL Studio MCP Server (`404kidwiz/fl-studio-mcp`) — https://policylayer.com/tools/404kidwiz-fl-studio-mcp.md - Homepage: https://github.com/404kidwiz/fl-studio-mcp - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "fl_list_library", "arguments": {} } } ``` ## Why fl_list_library is rated Low The tool appears to enumerate or display contents of FL Studio's library (patches, samples, presets, etc.) without creating, modifying, or deleting data. Listing operations are non-destructive reads with minimal blast radius if misused by an AI agent—worst case, the agent sees library metadata it shouldn't access, but no production data is harmed. From the tool's own definition: "Tool name 'fl_list_library' indicates a listing/enumeration operation. The 'list' verb conventionally retrieves or queries data without modifying state." ## Use case AI agents call fl_list_library to retrieve information from FL Studio MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FL Studio MCP Server: ```json { "version": "1", "default": "deny", "tools": { "fl_list_library": {} } } ``` ## Other tools on FL Studio MCP Server (109) - `fl_clear_pattern` — Destructive — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-clear-pattern.md - `fl_delete_marker` — Destructive — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-delete-marker.md - `fl_undo` — Destructive — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-undo.md - `fl_auto_mix` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-auto-mix.md - `fl_browser_nav` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-browser-nav.md - `fl_click_at` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-click-at.md - `fl_dismiss_popup` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-dismiss-popup.md - `fl_load_plugin` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-load-plugin.md - `fl_load_vst_preset` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-load-vst-preset.md - `fl_master_bus_clipper_optimizer` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-master-bus-clipper-optimizer.md - `fl_multiband_stereo_widener_matrix` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-multiband-stereo-widener-matrix.md - `fl_orchestral_articulation_mapper` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-orchestral-articulation-mapper.md - `fl_panic` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-panic.md - `fl_play_transport` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-play-transport.md - `fl_polyphonic_midi_to_audio_harmonizer` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-polyphonic-midi-to-audio-harmonizer.md - `fl_render_project` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-render-project.md - `fl_resampler_glitch_generator` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-resampler-glitch-generator.md - `fl_reset_ui` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-reset-ui.md - `fl_set_plugin_param` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-set-plugin-param.md - `fl_song_structure_mutator` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-song-structure-mutator.md - `fl_spectral_morphing_engine` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-spectral-morphing-engine.md - `fl_stop_transport` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-stop-transport.md - `fl_ui_navigate` — Execute — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-ui-navigate.md - `fl_ai_track_sheet_generator` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-ai-track-sheet-generator.md - `fl_catalog_vst_preset` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-catalog-vst-preset.md - `fl_get_channel_count` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-channel-count.md - `fl_get_context` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-context.md - `fl_get_current_pattern` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-current-pattern.md - `fl_get_marker` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-marker.md - `fl_get_mixer_state` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-mixer-state.md - …and 79 more: https://policylayer.com/tools/404kidwiz-fl-studio-mcp.md ## For agents This record is a snapshot.
