How to Set Up and Use Spline
The spline-mcp-server enables Claude to interact with the Spline 3D design tool through natural language, generating integration code for embedding and controlling Spline scenes in JavaScript, React, and Next.js applications using the @splinetool/runtime library. It covers object queries, event emission, variable management, playback control, and scene loading — giving developers working AI-generated starter code for Spline web integrations. Use it to skip manual API documentation lookups and get runnable code snippets directly from Claude.
Prerequisites
- Node.js 16 or later with npx available
- A Spline account with at least one published scene (spline.design)
- The @splinetool/runtime npm package in your web project for runtime code to execute
- An MCP-compatible client such as Claude Desktop
Add the server to Claude Desktop configuration
Open your Claude Desktop config file at ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%/Claude/claude_desktop_config.json (Windows) and add the spline-mcp-server entry.
{
"mcpServers": {
"spline": {
"command": "npx",
"args": ["-y", "spline-mcp-server"]
}
}
}Restart Claude Desktop
Quit and reopen Claude Desktop so it loads the new MCP server. npx will download spline-mcp-server on first use. No API key or environment variables are required.
Publish your Spline scene and copy the scene URL
In the Spline editor, click Export or Share, set visibility to Public, and copy the .splinecode URL. You will pass this URL to Claude when asking for integration code.
Install the Spline runtime in your project
Add @splinetool/runtime to the web project where you want to embed the Spline scene. This is the library that the generated code depends on.
npm install @splinetool/runtimeAsk Claude to generate integration code
Provide your scene URL and describe what interactions you need. Claude will use the MCP tools to produce working runtime code tailored to your framework.

}Prompts to try
Example natural-language prompts for generating Spline scene integrations.
- "Generate a React component that loads my Spline scene from https://prod.spline.design/abc123/scene.splinecode and triggers an animation when a button is clicked"
- "Write a Next.js page that embeds a Spline scene and hides the object named 'Overlay' after 3 seconds"
- "Create vanilla JavaScript that loads a Spline scene, finds an object called 'Cube', and changes its position on mouse move"
- "Show me how to use emitEvent to trigger a 'hover' event on the 'Logo' object in my Spline scene"Troubleshooting Spline
Generated code throws 'Cannot find module @splinetool/runtime'
Run 'npm install @splinetool/runtime' in your web project directory. The generated code imports from this package, which must be installed separately from the MCP server.
Scene fails to load in the browser with a CORS or 404 error
Make sure your Spline scene is published and set to Public visibility. The URL must end with .splinecode. Private or unpublished scenes will return 403 or 404 errors at runtime.
Claude says no spline tools are available
Verify the config uses 'spline-mcp-server' (with hyphens, not 'spline'). Restart Claude Desktop after editing the config. Run 'npx -y spline-mcp-server' in a terminal to confirm the package downloads without errors.
