Spline MCP Server

# Spline.design Integration Server This server provides comprehensive integration with Spline.design 3D scenes through multiple modes: 1. **MCP Server** - Full Model Context Protocol integration for Claude Desktop 2. **Webhook Server** - Standalone webhook support for data-driven visualizations 3. **Minimal Server** - Lightweight option with essential functionality ## Features - **Comprehensive 3D Object Management** - Create, modify, and delete any 3D object - Control positioning, rotation, scaling, and visibility - Generate runtime code for object interactions - **Runtime API Integration** - Direct integration with `@splinetool/runtime` for programmatic control - Generate ready-to-use JavaScript, React, and Next.js code - Create interactive animations and behaviors - Implement custom event handling and scene manipulation - **Advanced Material System** - Create layered materials with extensive customization - Support for all Spline material types and properties - Configure complex shading options - **Complete Event & Action System** - Support for 20+ event types (mouse, keyboard, physics, etc.) - Implementation of 15+ action types - Create complex event chains and conditional logic - **Webhook Integration** - Create webhooks to receive external data - Build real-time data visualizations - Connect with services like Zapier, IFTTT, n8n, or custom APIs ## Installation ### Option 1: Install and run locally ```bash # Clone the repository git clone https://github.com/yourusername/spline-mcp-server.git cd spline-mcp-server # Install dependencies npm install # Configure environment variables cp config/.env.example .env # Start the server in MCP mode (for Claude Desktop) npm start ``` ### Option 2: Run different server modes ```bash # Start in MCP mode (default) node bin/cli.js --mode mcp # Start in webhook mode node bin/cli.js --mode webhook # Start in minimal mode node bin/cli.js --mode minimal ``` ## Command-Line Options The server supports various command-line options through the unified CLI: ```bash # Get help node bin/cli.js --help # MCP mode with HTTP transport node bin/cli.js --mode mcp --transport http --port 3000 # MCP mode with stdio transport (for Claude Desktop) node bin/cli.js --mode mcp --transport stdio # Webhook server mode node bin/cli.js --mode webhook --port 3000 ``` ## Project Structure ``` spline-mcp-server/ ├── bin/ # Executable scripts │ └── cli.js # Unified CLI entry point ├── config/ # Configuration files │ ├── .env.example # Environment variables template │ └── *.json # JSON configuration files ├── docs/ # Documentation │ ├── INSTALLATION.md # Installation guide │ ├── USAGE_GUIDE.md # Usage instructions │ └── WEBHOOK_GUIDE.md # Webhook specific guide ├── examples/ # Example usage patterns ├── package-templates/ # Package.json templates for different modes ├── public/ # Web assets │ └── webhook-ui.html # Webhook UI interface ├── scripts/ # Shell scripts │ ├── install.sh # Installation script │ └── test-*.sh # Testing scripts ├── src/ # Source code │ ├── prompts/ # Prompt templates │ ├── resources/ # MCP resources │ ├── tools/ # MCP tools │ ├── utils/ # Utility functions │ └── index.js # Main MCP entry point ├── minimal.js # Minimal server implementation ├── simple-webhook-server.js # Standalone webhook server ├── LICENSE # License file ├── README.md # Project readme └── package.json # Unified package file ``` ## Using with Claude Desktop This server is designed to work with Claude Desktop in MCP mode: 1. Start the server in MCP mode with stdio transport: ```bash node bin/cli.js --mode mcp --transport stdio ``` 2. In Claude Desktop, access the MCP connection settings 3. Connect to the server 4. Start interacting with Spline.design through Claude ## Using Webhook Mode The webhook server provides a simple web interface for creating and testing webhooks: 1. Start the server in webhook mode: ```bash node bin/cli.js --mode webhook ``` 2. Open the web interface at http://localhost:3000 3. Create a webhook and obtain its URL 4. In Spline.design, configure the webhook in the Variables & Data Panel 5. Send test data to see your scene update in real-time ## Examples See the `examples/` directory for sample usage patterns and common workflows. ## Documentation For detailed documentation, see the files in the `docs/` directory: - [Installation Guide](docs/INSTALLATION.md) - [Usage Guide](docs/USAGE_GUIDE.md) - [Webhook Guide](docs/WEBHOOK_GUIDE.md) - [Testing Guide](docs/TEST_CASES.md) ## Contributing Contributions are welcome!
