readme

3D Asset Processing MCP

A comprehensive MCP server for processing, validating, optimizing, and analyzing 3D models with glTF/GLB support.

Features

Analysis: Get detailed model statistics including geometry, materials, animations, and performance metrics
Validation: Ensure 3D models meet standards using built-in checks
Basic Processing: Convert between glTF/GLB formats using gltf-pipeline
Advanced Processing: Apply Meshopt/Draco compression, texture optimization, and geometry processing using gltf-transform

Installation

Add to your MCP client configuration:

{
  "mcpServers": {
    "3d-asset-processing-mcp": {
      "command": "npx",
      "args": ["-y", "3d-asset-processing-mcp"]
    }
  }
}

All dependencies (gltf-pipeline, gltf-transform) are included - no additional setup required.

Available Tools

analyze_model: Analyze 3D models and provide detailed statistics
validate_model: Validate 3D models for compliance and compatibility
gltf-pipeline-executor: Basic glTF operations (conversion, format upgrade, simple compression)
gltf-transform-executor: Advanced glTF processing (Meshopt/Draco compression, texture optimization, geometry processing)
