Creator MCP features, limitations, and tools
See everything Creator MCP supports, what it doesn't support yet, its limits, and the tools your AI uses.
What you can do

| Preview | Filmstrips (evenly spaced or at chosen times), PNG images, and a playable preview card in Claude and ChatGPT |
| Export | Lottie JSON, dotLottie, MP4, WebM (with sound), PNG images |
| Workspace | Save to your LottieFiles workspace, open in Lottie Creator, load from your workspace |
| History | Restore any of the last 32 saved versions |
Not supported
| Feature | What to do instead |
|---|---|
| Expressions | Ask the AI to create the motion with keyframes |
| Repeaters | Ask the AI to duplicate the elements one by one |
| Boolean path operations (merge, subtract shapes) | Use masks for most cutout effects |
| WOFF font files | Use TTF, OTF, or TTC |
| Non-Latin scripts and emoji in the built-in font | Provide a font file that covers them (emoji may still not show) |
| JPG, WebP, and other image formats | Convert them to PNG first |
Video vs. Lottie: different limits
Some things look right in a preview or video but can't be saved as Lottie. Lottie export doesn't support:
- Repeating or mirrored gradients
- Gradients with their own transform (common in imported SVGs)
- Animated colors that include transparency
- Some text features (see Add text, fonts, and sound)
Some transforms, effects, masks, mattes, and images also need to sit on composition-level layers to export as Lottie. The AI can rearrange them for you.
Tip: If you need a Lottie file, say so at the start and ask the AI to check Lottie compatibility before it builds a complex scene.

Creator MCP tools
Creator MCP gives your AI a set of tools. You don't need to call them yourself; the AI uses them when you ask in plain words.
| Tool | What it does | When it appears |
|---|---|---|
creator_exec |
Builds, checks, edits, previews, and exports an animation | Always |
creator_docs |
Searches the Creator MCP reference and looks up methods | Always |
creator_document |
Lists animations and their files, lists or restores earlier versions, or resets an animation (with your confirmation) | Always |
creator_download_file |
Gets a download link for a file, or the status of a video being created | When file storage is available |
creator_delete_file |
Deletes an exported or media file, or cancels a video still being created | When file storage is available |
creator_import_media |
Uploads an image, SVG, Lottie, dotLottie, Rive, audio, or font file | When file storage and uploads are available |
creator_account |
Shows the connected LottieFiles account, workspace, and Drafts project | With a workspace connection |
creator_save_to_workspace |
Saves the animation to your workspace as a new file or new version | With a workspace connection and file storage |
creator_open_in_creator |
Saves the animation and gives a link to open it in Lottie Creator | With a workspace connection and file storage |
creator_load_from_workspace |
Loads a Lottie file from your workspace into the animation | With a workspace connection and file storage |
creator_preview |
Shows the animation playing in the chat (preview card) | In apps that support MCP Apps, such as Claude and ChatGPT |
In apps that support MCP Apps, you may also see creator_document_head, creator_describe_region, and creator_export_file. Only the preview card uses these, and most apps hide them.
Only three tools showing? If you only see creator_exec, creator_docs, and creator_document, the server you're connected to doesn't offer downloads, file deletion, or workspace tools. Check that you used https://creator.mcp.lottiefiles.com/mcp.
Suggested instructions for your AI agent
You can add these to your agent's instructions for better results:
Use Creator MCP for animation work. Before using unfamiliar methods, look them up with creator_docs. Use a named document for each independent animation. Inspect the existing scene before editing it; preserve unrelated elements. Name important elements so follow-up edits can target them. Review filmstrips and warnings before exporting. Deliver a working download or workspace link, not an MCP resource URI.
For developers: The AI builds animations by running JavaScript with the Creator API. Full details are in the developer docs: Tools & capabilities.
