MCP server for [Spline.design](https://spline.design) code generation and asset management.

## Overview

Spline.design is a 3D design tool that exports interactive scenes for the web. This MCP server provides:

- **Code Generation**: Generate React, Next.js, and vanilla JS integration code
- **Asset Management**: Download, cache, and validate `.splinecode` files
- **Integration Support**: WebSocket event sink
- **Helper Utilities**: URL building, event documentation, code snippets

> **Note**: Spline does not have a traditional REST API. Scenes are created in the Spline editor and exported as `.splinecode` files for runtime use.

## Spline V2 Compatibility

Spline V2 (released August 20, 2026) ships its own MCP server inside the rebuilt Spline desktop app that lets AI agents drive the editor directly — creating and modifying objects, materials, lights, cameras, booleans, particles, cloners, lathes, sky, variables, events, and states. See the [Spline V2 launch announcement](https://blog.spline.design/spline-v2) for details.

This server fills a **different, complementary niche**:

| Workflow stage | Tool |
|---|---|
| **Authoring** — building / editing the scene in the editor | [Spline V2 MCP](https://blog.spline.design/spline-v2) (bundled with the Spline desktop app) |
| **Embedding** — putting the exported scene into your React / Next.js / v…
