Which MCP Server Should You Choose?
Choose FableCut when:
You need dedicated capabilities in the Multimedia Process domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: 3 video + 4 audio tracks with drag, trim, split, snap, undo/redo, Live timeline updates via server-sent events with JSON project file, Direct manipulation of clips on preview monitor (move, resize, rotate).
Zero-dependency browser video editor that AI agents drive through a JSON timeline. MCP tools to add/patch clips, keyframes, transitions, text animations and filters, import media, and analyze a reference video into an edit blueprint (shots, beats, BPM, drop); the open editor UI live-reloads on every change and exports via ffmpeg.
The first MCP server for Final Cut Pro. 53 tools that parse, edit, and generate FCPXML timelines — health checks, flash frame detection, chapter markers, rough cuts, NLE export. 912 tests, MIT licensed.

Select FableCut when you need capabilities focused on multimedia process and Fcpxml MCP Server when you require tools for multimedia process.
Read a timeline or project without changing it. Use this first to understand what you are working with. Actions: list_projects, analyze_timeline, analyze_pacing, list_clips, list_markers, list_roles, list_keywords, list_effects, list_templates, list_library_clips, list_compound_clips, list_connected_clips, filter_by_role.
diagnose
Find problems in a timeline: gaps, flash frames, duplicates, dead air, and beat structure. Read-only. Run before editing. Actions: validate_timeline, detect_gaps, detect_duplicates, detect_flash_frames, detect_silence_candidates, detect_media_silence, detect_beats, find_short_cuts, find_long_clips, diff_timelines.
edit
Change clips on the timeline: insert, delete, trim, split, reorder, retime, remove silence, and attach audio, B-roll or transitions. Writes a new file. Actions: insert_clip, delete_clips, trim_clip, split_clip, reorder_clips, change_speed, rapid_trim, add_transition, add_audio, add_connected_clip, assign_role, fill_gaps, fix_flash_frames, remove_silence_candidates, remove_media_silence.
mark
Add or import markers and chapters, including from SRT/VTT subtitles, transcripts, and beat analysis. Actions: add_marker, batch_add_markers, import_srt_markers, import_transcript_markers, import_beat_markers, snap_to_beats.
generate
Build new timeline structure from source clips: rough cuts, montages, A/B roll, templates and compound clips. Actions: auto_rough_cut, generate_ab_roll, generate_montage, apply_template, create_compound_clip, flatten_compound_clip, import_edl_json.
transcript
Transcribe source media locally and edit the timeline by what was SAID rather than by timecode. Also removes filler words. Actions: transcribe_media, edit_by_transcript, remove_filler_words, transcript_pack.
deliver
Get the edit out: export to other NLEs, CSV, EDL and stems, reformat, relink media, or push straight into a running Final Cut Pro. Exports and push refuse a cut with no rendered preview of its current state (pass confirm_unreviewed=true to ship anyway). Actions: export_csv, export_edl, export_fcp7_xml, export_resolve_xml, export_role_stems, reformat_timeline, relink_media, push_to_fcp, list_fcp_libraries.
preview
See the edit without opening Final Cut Pro. Render a proxy video of the timeline, a contact sheet of every cut, a single frame, or a filmstrip-plus-waveform check read from the SOURCE MEDIA rather than from the XML. Run preview_check to confirm a fix actually landed. Actions: preview_render, preview_sheet, preview_frame, preview_check, preview_timeline.
watch
Close the round-trip. Watch the Final Cut Pro export folder, detect the XML the moment it lands, and diff it against the last one seen. Pair with deliver.push_to_fcp for a full loop: push in, edit, Cmd-E, watch_pull. Actions: watch_start, watch_status, watch_stop, watch_pull.
index
The analysis cache under ~/.fcp-mcp/index.db. index_status shows what is cached and how old it is; index_build warms it for every source in a timeline (args: filepath, with_transcript); index_clear drops it. Every other tool works with the index off (FCP_MCP_INDEX=off) — this only makes the second question fast. Actions: index_status, index_build, index_clear.
scenes
Shot boundaries. detect_scenes reads every source in a timeline and reports cuts in timeline time (args: filepath, clip_name?, backend auto|content|adaptive|ffmpeg, threshold?, min_scene_len=0.5); scenes_to_markers writes a marker at each cut; scenes_split cuts the clips there. PySceneDetect via the scenes extra, ffmpeg without it — the result names which one answered. Actions: detect_scenes, scenes_to_markers, scenes_split.
organize
Bulk library logging and the ledger. organize_auto proposes keywords per clip from cached captions and the transcript (apply=true writes them). Select clips with clip_name (glob), keyword and/or role, then organize_keywords (keywords, mode add|remove|replace), organize_rate (rating favorite|rejected|clear) or organize_roles (audio_role, video_role); each writes a _organized copy. history lists every recorded operation for the file's folder (limit); undo (n) moves the outputs of the last n writes into the journal's undone/ folder — it never deletes and refuses when a file changed since it was written. Actions: organize_auto, organize_keywords, organize_rate, organize_roles, history, undo.
