OpenToonz MCP

Let an AI assistant animate inside OpenToonz, the open-source 2D studio tool, and keep every frame editable.

Made entirely with this server's tools. The character, background and timing are real OpenToonz vector levels, xsheet cells and keyframes, so you can open the scene and keep animating by hand.

Why I built this

Most "AI animation" today produces a finished video you can't edit. Animators need the opposite: drawings they can fix, timing they can retime, and a scene they can hand to the next person in the pipeline.

OpenToonz is the open-source release of Toonz, the software Studio Ghibli customised and used on its films. It already has everything a 2D pipeline needs: vector levels, an xsheet, pegbars, cameras and a compositor. What it lacked was a way for an assistant to use it.

OpenToonz MCP is that bridge. You describe a shot. The assistant lays it out, draws key poses, in-betweens them, times them on ones, twos or threes, adds camera work, and renders. The result is a normal OpenToonz scene. You can open it, change anything, save it, and ask the assistant to continue. Your edits are kept.

Who it's for

• Animators and directors who want fast layouts, animatics, in-betweens and camera passes they can then finish by hand.
• Indie studios and solo creators making shorts, explainers, music videos or game cutscenes without a full crew.
• Teachers and students of animation. The tools follow the classic principles (slow in/out, arcs, anticipation, follow-through), so the output is a worked example you can inspect frame by frame.
• Developers building creative AI tools who need a real, inspectable 2D pipeline rather than pixels.
