What it does
Final Cut Pro is an agent skill from DareDev256/fcp-mcp-server. Edit Final Cut Pro timelines with natural language via FCPXML. Use when the user wants to analyze, cut, trim, mark up, transcribe, montage, or export a Final Cut Pro project, mentions .fcpxml or .fcpxmld files, asks to remove silence or filler words from a video edit, wants a rough cut assembled from source clips, wants markers or chapters added from a transcript or SRT, or wants an edit pushed into a running Final Cut Pro. Requires the fcp-mcp-server MCP server.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Media & Creative, covering Transcription and MCP servers. It works with Model Context Protocol, Python and ElevenLabs. The repository describes itself as: MCP server for Final Cut Pro XML. Lets Claude read, edit and generate real timelines: cut detection, markers, roles, transcript-based editing. Published on PyPI as fcp-mcp-server. The licence is MIT.
When your agent uses it
- The user wants to analyze
- Export a Final Cut Pro project
- Mentions .fcpxml
- Asks to remove silence
Example prompts
- “/final-cut-pro”
Requirements
- A credential in ELEVENLABS_API_KEY
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- inspect with action analyze_timeline for shape, duration, resolution.
- diagnose with action validate_timeline for gaps, flash frames, duplicates.
- Read the preview:// resource to actually SEE the timeline before
What it can do on your machine
Read from SKILL.md and the folder at commit 2b39ac0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
ELEVENLABS_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Final Cut Pro loads about 1.9k tokens when it runs. Until then it costs about 120 tokens; SKILL.md has 1,023 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Final Cut Pro editing via FCPXML
Before you touch anything
Always inspect then diagnose before you edit. Timelines carry structure
that is not obvious from a filename, and an edit against a wrong assumption is
expensive to undo.
inspectwith actionanalyze_timelinefor shape, duration, resolution.diagnosewith actionvalidate_timelinefor gaps, flash frames, duplicates.- Read the
preview://<path>resource to actually SEE the timeline before you change anything. It renders a self-contained HTML timeline, including connected clips on their own lane rows, so you can see B-roll and audio layers, not just the primary storyline.
The seven groups
| Group | Use it for |
|---|---|
inspect | Read-only understanding. Start here, always. |
diagnose | Find problems: gaps, flash frames, dead air, duplicates, beats. |
edit | Change clips: insert, delete, trim, split, reorder, retime, remove silence. |
mark | Markers and chapters, including SRT/VTT and beat import. |
generate | Build new structure: rough cuts, montages, A/B roll, templates, and import_edl_json from a video-use cut list. |
transcript | Transcribe locally, then edit or clean up by what was SAID. transcript_pack puts the whole shoot on one page — read it before planning a dialogue edit. Every action takes backend: "elevenlabs" for speaker labels and audio events; that uploads the media to ElevenLabs and needs ELEVENLABS_API_KEY — the default local never leaves the machine. |
deliver | Export to other NLEs, reformat, relink, push into FCP. |
preview | SEE the edit: proxy render, contact sheet, and a filmstrip+waveform read from the source media. |
watch | Close the round-trip: notice the operator's Cmd-E export and diff it against the last one. |
index | The analysis cache. index_status says how old it is; index_build warms every source in a timeline; index_clear drops it. Nothing depends on it. |
scenes | Shot boundaries from the pixels. detect_scenes lists cuts per clip in source and timeline time (PySceneDetect when installed via [scenes], else ffmpeg's coarser scene filter); scenes_to_markers drops a marker on each; scenes_split cuts the clips there. Results are cached in the index. |
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 by clip_name glob, keyword and/or role, then organize_keywords (add/remove/replace), organize_rate (favorite/rejected/clear) or organize_roles — each writes a _organized copy. history lists every recorded operation for the file's folder; undo moves the last n outputs into the journal's undone/ folder (never deletes, refuses if a file changed since). |
find | "Where is the bit where…" as a router. find_shots ranks moments by what was said (transcript), what was logged (names, keywords, notes, markers, audio events) and, with the [find] extra and a downloaded local model, what the frames look like — the first line names which tiers answered and why one could not. find_index warms scenes and captions and reports which clips have no transcript (never transcribes, never online). find_to_timeline assembles the hits into a _found selects reel with a diversity score. |
Every call takes {"action": "...", "args": {...}}. If you pass an action the
group does not own, the error lists the valid ones — read it rather than
guessing.
FCPXML facts that will bite you
- Time is rational, never float.
3600/2400sis 1.5 seconds. Never do float math on timecode and never round it yourself. offsetis the timeline position.startis the source in-point. They are different numbers and confusing them silently shifts an edit.- Library clips and timeline clips are different elements.
<asset-clip>lives in the library,<clip>lives on the timeline. - Markers are children of clips, not siblings.
- The
<spine>is the primary storyline. Connected clips hang off spine clips by lane: positive is above (video), negative is below (audio). .fcpxmldbundles are directories, wrappingInfo.fcpxmlplus sidecar data. Sidecars must be preserved on save or object-tracking and Cinematic data is destroyed.- Duplicate clip names are common. Prefer element-based operations over name lookups where a tool offers both.

Silence removal: pick the right one
There are two detect-then-fix pairs, and they are not interchangeable. Both
follow the same split as every other detect/fix pair in this server: the
detector lives in diagnose, the fixer lives in edit.
detect_media_silence(diagnose) →remove_media_silence(edit) reads the actual source audio with ffmpeg. Accurate, slower, needs ffmpeg installed.detect_silence_candidates(diagnose) →remove_silence_candidates(edit) uses timeline heuristics only. Fast, no ffmpeg, and it guesses.
Use the media versions when correctness matters. Say which one you used.
Working order that tends to hold
inspect→diagnose→ read thepreview://resource.transcriptwith actiontranscript_packif the edit is dialogue-driven — one page of everything said, so the plan is made from the words rather than the clip names.generatefor the assembly,editfor the refinement,markfor chapters.previewwith actionpreview_checkover the range you changed, before offering the edit as done. This is what makes the edit non-blind. Thepreview://resource andpreview_timelineboth draw from the XML — they show what was WRITTEN, so they cannot tell a fixed cut from a broken one.preview_checkreads the media. Do not substitute one for the other, and do not skip it because the tool call reported success.deliver, either exporting orpush_to_fcpinto the running app.watchwith actionwatch_startonce per session, thenwatch_pullafter the operator exports. Final Cut Pro has NO programmatic export — Apple never shipped one — so the loop only closes when they press Cmd-E. Say so plainly rather than waiting in silence.
Do not
- Do not edit without a diagnose pass. Flash frames and gaps compound.
- Do not assume ffmpeg or Whisper are installed. Both degrade gracefully and return nothing rather than erroring, so check the response.
- Do not read a
preview_rendersummary past the word UNVERIFIED. It means the rendered file's duration could not be read back, so nothing about that render has been confirmed. - Do not ignore a
Substituted:line. The proxy renders transitions as hard cuts, so a dissolve in the timeline is NOT what you are looking at. - Do not claim an edit landed in Final Cut Pro unless
push_to_fcpwas called and reported success. Writing an .fcpxml file is not the same as importing it. - Do not trust a tool's own success message as proof the timeline looks
right. Read
preview://and look.
