Summary

Batch E of #1180: an MCP client can now manage a project's name and media, and create a project.

  • setProjectInfo renames the project (project.title, trimmed and never empty, as the editor's name field commits it).
  • importMedia adds a video or audio file to the project's media, through the same change as DocumentService.addAsset (documentWithAsset, now shared). The path must be absolute, exist and have a supported extension. The file is measured with the hidden-window probe before the project is read; a probe failure is not fatal, as in the editor. In the app, the file is granted to the renderer so the editor can play it.
  • removeMedia removes an asset with DocumentService.removeAsset's own change (documentWithoutAsset), but refuses while a clip or audio track still uses it, naming them.
  • createProject (a media tool) creates an empty project or one from a video file, through DocumentService.createProject, so it takes the preset for new projects as the editor's New does. It returns a checkpoint, as stopRecording does.
  • Deleting a project is left out on purpose and documented as such.

Routing. The three project tools run in the shared tool runner like any document edit. The project open in the editor changes there live, as one undo step. Any other project needs a checkpoint first. MCP edits gates them. The app's channel serves them, so openscreen mcp forwards them to the running app. A lost answer is never re-run locally.

Docs. The tool descriptions, mcp-server.md, ai-editing.md (all 7 translations) and the openscreen-demo skill are updated. The shared addAudio texts no longer claim that nothing can import a file.

None: no UI change.

Testing

  • New tests run over the real HTTP server, with a real DocumentService (openscreen-mcp-server.test.ts):
    • rename through the editor;
    • import a video or audio file, measured, unmeasurable, and the path refusals;
    • the edits-off refusal;
    • remove-media guard;
    • closed project edited on its file after a checkpoint.
  • The createProject tests (media-tools.test.ts) cover:
    • an empty project, then edited at once;
    • a project from a video, with its zooms;
    • refusals that create nothing;
    • the edits-off gate.
  • Checks run: npx tsc --noEmit, npx tsc -p tsconfig.test.json --noEmit and npm run lint, plus Vitest on electron/ai-edition, electron/mcp and src/lib/ai-edition.
  • One export test timed out under full parallel load. It passes alone and is untouched by this change.
  • The Electron app was not launched. The real hidden-window probe of an audio file is therefore untested here.

Summary by CodeRabbit

  • New Features
    • MCP clients can create empty projects or start projects from an existing video, rename projects, and add video or audio media.
    • MCP clients can remove media that isn’t in use by the timeline; removing it from a project does not delete the source file.
    • These project changes require MCP Editing to be enabled.
  • Documentation
    • Updated MCP guides to describe the project and media tools.

📝 Walkthrough

MCP tools can now create and rename projects, import and remove project media, and create projects from existing videos. Asset updates include related timeline cleanup. Edit-switch checks, tests, and documentation cover the new operations.

Changes: MCP project and media operations

Layer / File(s) Summary
Asset updates and audio import guidance
electron/ai-edition/document-service.ts, electron/ai-edition/agent-tools.ts, electron/ai-edition/deep-agent/service.ts
Document helpers validate, add, and remove assets, including related timeline data. Audio guidance points to importMedia where available.
Project metadata and media tools
electron/mcp/project-tools.ts, electron/mcp/openscreen-mcp-server.ts, electron/ipc/handlers.ts, electron/mcp/app-channel.ts, electron/mcp/openscreen-mcp-server.test.ts
MCP tools rename projects, import media, and remove unused media. The server applies edit-switch checks, prepares imports, and routes project-tool calls. Tests cover validation, media handling, and closed-project edits.
Project creation from empty or video input
electron/mcp/media-tools.ts, electron/mcp/media-tools.test.ts
createProject creates an empty project or one based on a video path, and returns project and checkpoint details. Tests cover successful creation and failure cases.
Tool guidance and documentation
skills/openscreen-demo/SKILL.md, technical-documentation/architecture/mcp-server.md, website/docs/ai-editing.md, website/i18n/*/docusaurus-plugin-content-docs/current/ai-editing.md
The skill and documentation describe project and media tools, edit-switch requirements, and documented tool lists across supported translations.

An existing video could be exported without the documented privacy check. Project creation can also return an error without identifying a project it created, and imported .oga audio may be unreadable in the editor. Address these issues before merging.

`deps.documents.createProject` failures separately and return an error result
stating no project was created, without attempting checkpoint creation. Update
`checkpointOf` to catch failures from `deps.runTool` or parsing and return null,
preserving the created `projectId` when checkpoint creation fails across the
shared checkpoint paths.

setProjectInfo, importMedia and removeMedia run in the tool runner like any
edit, so the project open in the editor changes there live, and openscreen mcp
forwards them to the running app. createProject is a media tool, empty or from a
video, and returns a checkpoint as stopRecording does. Deleting a project stays
out on purpose.
