# CLAUDE.md — fcp-mcp-server
|
||||
|
||||
## Idioma (MANDATORY)
|
||||
|
||||
Responder **sempre em português** ao usuário, sem exceção. Nunca responder em
|
||||
inglês nas mensagens de chat/prompt — inclusive resumos, atualizações de
|
||||
progresso e confirmações. Comentários e nomes de código continuam em inglês
|
||||
normalmente; a regra é sobre a comunicação com o usuário.
|
||||
|
||||
## What This Is
|
||||
|
||||
MCP server that reads/writes Final Cut Pro XML (FCPXML) files. 62 tools for timeline analysis, batch editing, QC, generation, multi-track support, media relink, NLE export, transcript-based editing (local Whisper), and LIVE FCP control (push_to_fcp / list_fcp_libraries via Apple events). Reads FCPXML 1.8–1.14 (incl. `.fcpxmld` bundles with sidecar preservation), writes 1.13 by default. Dual-mode (XML + Live) direction: `code/docs/CAPABILITY-AUDIT-2026-06.md`.
|
||||
|
||||
## Architecture
|
||||
|
||||
Toda a estrutura do projeto fica em `code/`. A pasta `admin/` fica na raiz (fora de `code/`).
|
||||
|
||||
```
|
||||
code/server.py — MCP server entry point. All 62 tool definitions, handlers, resources, prompts.
|
||||
Dispatch dict pattern: TOOL_HANDLERS maps tool names → async handler functions.
|
||||
|
||||
code/fcpxml/parser.py — Reads FCPXML → Python objects (Timeline, Clip, ConnectedClip, Marker, etc.)
|
||||
code/fcpxml/writer.py — Writes modifications back to FCPXML. Handles markers, trimming, gaps, transitions.
|
||||
code/fcpxml/rough_cut.py — Generates new timelines from source clips (rough cuts, montages, A/B rolls).
|
||||
code/fcpxml/diff.py — Timeline comparison engine. Detects added/removed/moved/trimmed clips & markers.
|
||||
code/fcpxml/export.py — DaVinci Resolve FCPXML v1.9 export + FCP7 XMEML v5 export for cross-NLE workflows.
|
||||
code/fcpxml/models.py — Data classes: TimeValue, Timecode, Clip, ConnectedClip, CompoundClip, Timeline, etc.
|
||||
code/fcpxml/media_intel.py — Real media analysis. Audio silence detection + beat detection.
|
||||
code/fcpxml/dtd.py — Validates output against Apple's official DTDs.
|
||||
```
|
||||
|
||||
## Key Patterns
|
||||
|
||||
- **TimeValue**: All times are rational fractions (numerator/denominator) matching FCPXML's `"600/2400s"` format. Never use floats for time math.
|
||||
- **_parse_project()**: Helper that parses FCPXML and returns `(tree, timeline, project)` tuple. Most handlers start with this.
|
||||
- **generate_output_path()**: Creates `_modified`, `_chapters`, etc. suffixed output paths so originals aren't overwritten.
|
||||
- **Tool handlers**: Each tool has its own `async def handle_<name>(arguments: dict)` function. All return via `_text_result(text)` which wraps strings in the MCP `TextContent` list.
|
||||
- **Connected clips**: Clips with `lane` attribute hang off spine clips. Positive lane = above (video), negative = below (audio). Secondary `<storyline>` elements also contain connected clips.
|
||||
- **XMEML export**: Converts spine-based model to track-based model. Primary storyline → Track 0, connected clip lanes → higher tracks.
|
||||
|
||||
## Running
|
||||
|
||||
```bash
|
||||
cd code && uv run server.py # Start MCP server
|
||||
cd code && uv run --extra dev pytest tests/ -v # Run tests
|
||||
```
|
||||
|
||||
## Registro de Experiências e Boas Práticas (MANDATORY)
|
||||
|
||||
Sempre que um problema de estrutura ou um erro recorrente for detectado e
|
||||
corrigido, **registre-o** em `code/Engine/docs/05_EXPERIENCIAS.md` (template já
|
||||
presente no arquivo). Antes de concluir qualquer alteração/correção, aplique e
|
||||
verifique as boas práticas e o checklist final em
|
||||
`code/Engine/docs/06_BOAS_PRATICAS.md`.
|
||||
|
||||
## Pre-Commit (MANDATORY)
|
||||
|
||||
Padrão do sistema: **sempre após concluir uma correção, o sistema é
|
||||
automaticamente executado/validado.** Acione o script único a cada correção:
|
||||
|
||||
```bash
|
||||
cd code && ./Engine/run_after_fix.sh
|
||||
```
|
||||
|
||||
Ele roda o lint (zero erros) e toda a suíte de testes, e falha se qualquer um
|
||||
não passar. Equivalente a rodar manualmente os dois comandos abaixo.
|
||||
|
||||
## Executar o App Localmente (MANDATORY)
|
||||
|
||||
Sempre que uma alteração for feita no app (MacApp/) durante o período de
|
||||
implementação, **compile e rode o programa localmente no computador** para
|
||||
validar visualmente a alteração, além de rodar os testes:
|
||||
|
||||
```bash
|
||||
cd code && ./MacApp/build_app.sh --run # compila e abre o app localmente
|
||||
```
|
||||
|
||||
Regra geral: após qualquer alteração, o app deve ser executado localmente
|
||||
antes de concluir a tarefa. Se houver erro de compilação, corrija antes de
|
||||
seguir.
|
||||
|
||||
Before committing ANY changes, run both:
|
||||
```bash
|
||||
cd code && ruff check . --exclude docs/ # Lint — must pass with zero errors
|
||||
cd code && pytest tests/ -v # Tests — all must pass
|
||||
```
|
||||
CI runs both on every push to main. If either fails, the commit gets an X on GitHub. Fix lint errors before committing, not after.
|
||||
|
||||
## Testing
|
||||
|
||||
1032 tests across 24 files. `test_models.py` covers TimeValue arithmetic, Timecode parsing/formatting, Clip properties, validation models, and Timeline helpers. `test_writer.py` covers insert_clip, add_marker (all types), trim_clip, delete_clip, split_clip, and change_speed operations. `test_server.py` covers MCP tool handlers, parsers, and dispatch. `test_rough_cut.py` covers RoughCutGenerator. `test_features_v05.py` covers connected clips, roles, timeline diff, reformat, silence detection, export, and backward compatibility. `test_marker_pipeline.py` covers build_marker_element shared builder, batch auto-modes, clip index duplicate-name behavior, and write_fcpxml output format. `test_refactored_helpers.py` covers _index_elements, _iter_spine_clips, _find_spine_clip_at_seconds, _resolve_clip_duration, _make_asset_clip, _format_batch_result, and serialize_xml edge cases. `test_transcribe.py` covers phrase/filler span matching, range merge/invert algebra, whisper graceful degradation, and transcript-driven handler cuts against cached transcripts. `test_media_intel.py` covers silencedetect stderr parsing, source-to-timeline mapping, parameter bounds, and real-WAV ffmpeg integration (skips without ffmpeg; CI installs it). Tests use `examples/sample.fcpxml` as fixture data and inline XML fixtures. Tests create temp files and clean up after.
|
||||
|
||||
## FCPXML Gotchas
|
||||
|
||||
- FCPXML uses rational time everywhere: `"3600/2400s"` = 1.5 seconds
|
||||
- `offset` in clips is the timeline position, `start` is the source media in-point
|
||||
- Library clips (`<asset-clip>`) are different from timeline clips (`<clip>`)
|
||||
- Markers are children of clips, not siblings
|
||||
- The `<spine>` element is the primary storyline — clips go here
|
||||
- `.fcpxmld` bundles are DIRECTORIES wrapping `Info.fcpxml` + sidecar data files — sidecars must be copied on save or object-tracking/Cinematic data is destroyed
|
||||
- `code/examples/sample.fcpxml` is NOT DTD-conformant (pre-`media-rep` assets, sequence-level chapter markers) — don't use it as a DTD-validity fixture
