Usage

This MCP server can be used with Claude to interact with Spline's features. Here are some examples of how to use it:

Basic Operations

Export my Spline scene with ID "abc123" to GLB format

Import the 3D model from "https://example.com/model.glb" into my Spline project

Get details for my Spline scene with ID "abc123"

List my available Spline scenes

Animation Operations

Create an animation named "Rotate" for the cube object in my scene

Trigger the "Bounce" animation for the ball object

Create an onClick animation that makes an object move up when clicked

List all animations in my scene

Animation Examples

Creating a Simple Rotation Animation

Create an animation named "Spin" for object "cube-123" in scene "abc456" with keyframes for rotation

Creating an Event-Based Animation

Create an onClick animation named "Grow" for object "button-123" in scene "abc456" that scales the object to 1.5x its size

Triggering Animations

Trigger the "Pulse" animation for object "heart-123" in scene "abc456" with loop enabled
