Tweens Motion Engine

A local MCP server that lets an assistant create editable animations, inspect frames and export GIF or MP4 files in a chosen workspace.

What you can do

Create and edit animations in a local workspace, with frames kept editable rather than baked into a final file. Inspect individual frames to review timing and content. Export finished animations as GIF or MP4 into the chosen workspace.

When to use it

Useful when you want an assistant to build or adjust short animations and produce shareable GIF or MP4 output without leaving the conversation, especially for small motion graphics or frame-by-frame work.

Requirements

Runs as a local process over stdio, installed from the npm package tweens-cli, so Node.js and npm are needed. A local workspace directory must be chosen for the animation files and exports. No authentication, environment variables or headers are declared. Desktop only.
