# fl_delete_marker Delete a marker from the playlist. Agent View of the PolicyLayer registry record for `fl_delete_marker`. HTML page: https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-delete-marker ## Facts - Tool: `fl_delete_marker` - 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: Destructive (Critical risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Hidden ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "fl_delete_marker", "arguments": {} } } ``` ## Why fl_delete_marker is rated Critical The tool permanently removes a marker object from FL Studio's playlist. Markers are project organization artifacts that users create and rely on; deletion cannot be undone without undo history. While the blast radius is narrower than deleting entire tracks or projects, it still constitutes irreversible data loss. Destructive is the appropriate category per the rules (Destructive > Execute > Write > Read). From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a marker from the playlist' — this is an irreversible removal of data." ## Use case AI agents call fl_delete_marker to permanently remove resources in FL Studio MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo. ## Recommended policy (PolicyLayer) Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FL Studio MCP Server: ```json { "version": "1", "default": "deny", "hide": [ "fl_delete_marker" ] } ``` ## 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_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 - `fl_get_mixer_track_count` — Read — https://policylayer.com/tools/404kidwiz-fl-studio-mcp/fl-get-mixer-track-count.md - …and 79 more: https://policylayer.com/tools/404kidwiz-fl-studio-mcp.md ## For agents This record is a snapshot.
