MCP Three - 3D Model Processing Server

A Model Context Protocol (MCP) server specialized for working with 3D models, specifically GLTF/GLB files. This server provides tools to convert 3D models into React Three Fiber JSX components and analyze model structures.

Features

• GLTF/GLB to JSX Conversion: Convert 3D models into reusable React Three Fiber components

• Model Structure Analysis: Inspect and debug 3D model hierarchies and properties

• Performance Optimization: Support for instancing, mesh simplification, and texture optimization

• TypeScript Support: Generate type-safe React components with proper TypeScript definitions

Tools Available

1. gltfjsx

Converts GLTF/GLB 3D model files into declarative React (react-three-fiber) JSX components.

Features:

• TypeScript definitions generation

• Mesh and material instancing for performance

• Texture format conversion and optimization

• Mesh simplification

• Shadow casting/receiving setup

• Bone layout for animations

• Metadata preservation

2. get-model-structure

Analyzes and returns the structure of a GLTF/GLB model file as JSON. Useful for debugging complex models and understanding their hierarchy before conversion.

Getting Started

Add this server to your MCP client configuration:

Supported File Formats

• .gltf - GLTF JSON format

• .glb - GLTF Binary format

Common Use Cases

1. Converting 3D Models for Web Apps: Transform GLTF/GLB files into optimized React components

2. Model Debugging: Inspect model structure and properties before integration

3. Performance Optimization: Generate instanced meshes and optimized textures

4. Animation Setup: Prepare models with proper bone layouts for animations
