One bridge, the full workflow

From an empty scene to the final render.

The useful parts of Cavalry’s scripting API, shaped into tools an agent can use predictably.

01

Build scenes

Create compositions, text, paths, groups, and production-ready layer structures without leaving your conversation.

LayersTypographyEditable paths
02

Shape the motion

Set keyframes, tune Magic Easing, sequence layers, and apply a motion harness built around restrained defaults.

KeyframesEasingStagger
03

Finish the frame

Control shaders, SkSL, filters, masks, palettes, assets, render queues, and the details that make work feel finished.

Three steps

No extra environment to assemble.

Cavalry, a compatible MCP client, and the bridge. That’s the whole setup.

  1. 1

    Install the bridge

    Open the signed macOS app once. It places the UI Script where Cavalry expects it.

  2. 2

    Start it in Cavalry

    Open Window → Scripts → Cavalry MCP Bridge. The panel shows version, status, and every request.

  3. 3

    Create from Codex

    Describe the scene, inspect the result, and refine it through 78 focused tools—without Cavalry CLI.

Designed for real scenes

Broad control. Narrow permissions.

Every operation is named, validated, logged, and allowlisted. The bridge never evaluates arbitrary JavaScript received over MCP.
