What it does

Fcpxml is an agent skill from DareDev256/fcp-mcp-server. Work with Final Cut Pro timelines and .fcpxml/.fcpxmld files. Use when the user mentions FCPXML, Final Cut Pro or FCP, asks to analyse or quality-check a timeline, batch-edit clips, build a rough cut, manage markers, pull a transcript, relink media, or export an edit to another NLE such as Premiere or Resolve.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol, YouTube and Python. 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 mentions FCPXML
  • Asks to analyse
  • Quality-check a timeline
  • Batch-edit clips

Example prompts

  • “/fcpxml”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Never overwrite originals. All write operations create _modified, _chapters, etc. suffixed files.
  2. Times are rational fractions. FCPXML uses "600/2400s" format — never convert to floats.
  3. Always analyze before fixing. Run detection tools first, show the user what was found, then offer batch fixes.
  4. Connected clips use lanes. Positive lane = above primary storyline (video/titles), negative = below (audio).
  5. Compound clips can be nested. Use list_compound_clips to understand structure before flattening.
  6. Export formats differ. Resolve XML flattens compounds. FCP7 XML converts spine-based to track-based model.

What it can do on your machine

Read from SKILL.md and the folder at commit 1a02bd6. 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 no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fcpxml loads about 1.7k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 698 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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.

Work with Final Cut Pro timelines and .fcpxml/.fcpxmld files. Use when the user mentions FCPXML, Final Cut Pro or FCP, asks to analyse or quality-check a timeline, batch-edit clips, build a rough cut, manage markers, pull a transcript, relink media, or export an edit to another NLE such as Premiere or Resolve.

FCPXML MCP — Agent Skill

Workflow Chains

When the user describes a high-level intent, chain tools in this order:

QC Pipeline

analyze_timeline → detect_flash_frames → detect_gaps → detect_duplicates → validate_timeline Then offer fixes: fix_flash_frames → fill_gaps

YouTube Chapter Export

list_markers (format: "youtube") → format output for copy-paste If no chapters exist: analyze_pacing → suggest chapter points → batch_add_markers

Rough Cut Assembly

list_library_clips → list_keywords → discuss structure → auto_rough_cut or generate_montage

Beat-Synced Music Video

import_beat_markers → auto_rough_cut or generate_montage → snap_to_beats

Cross-NLE Handoff

export_resolve_xml (for Resolve) + export_fcp7_xml (for Premiere/Pro Tools)

Silence Cleanup

detect_silence_candidates → review results → remove_silence_candidates

Timeline Comparison

diff_timelines → summarize changes for revision log

Social Reformat

reformat_timeline with preset → note that framing adjustments still needed in FCP

Key Rules

  1. Never overwrite originals. All write operations create _modified, _chapters, etc. suffixed files.
  2. Times are rational fractions. FCPXML uses "600/2400s" format — never convert to floats.
  3. Always analyze before fixing. Run detection tools first, show the user what was found, then offer batch fixes.
  4. Connected clips use lanes. Positive lane = above primary storyline (video/titles), negative = below (audio).
  5. Compound clips can be nested. Use list_compound_clips to understand structure before flattening.
  6. Export formats differ. Resolve XML flattens compounds. FCP7 XML converts spine-based to track-based model.

Can I use Fcpxml in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add DareDev256/fcp-mcp-server --skill fcpxml -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/fcpxml, .gemini/skills/fcpxml, .github/skills/fcpxml and .opencode/skills/fcpxml in your project.

What does Fcpxml need to run?

SKILL.md names no scripts, command-line tools or credentials: Fcpxml is instructions for the agent only.

Does Fcpxml access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Fcpxml safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Fcpxml use?

Fcpxml is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Fcpxml use?

About 1.7k tokens (SKILL.md is roughly 6.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
