Sketchfab MCP Server

A Model Context Protocol (MCP) server for interacting with Sketchfab's 3D model platform. This MCP allows you to search, view details, and download 3D models from Sketchfab directly through Claude or Cursor.

Features

• Search for 3D Models: Find models on Sketchfab using keywords, tags, and categories
• View Model Details: Get comprehensive information about specific models
• Download Models: Download models in various formats (gltf, glb, usdz, source)

Prerequisites

• Node.js 18 or higher
• A Sketchfab API key (for authentication)

Installation

1. Clone this repository

2. Install dependencies:

npm install

3. Build the project:

npm run build

node build/index.js --api-key YOUR_API_KEY

Alternatively, you can set the `SKETCHFAB_API_KEY` environment variable:

export SKETCHFAB_API_KEY=YOUR_API_KEY
npm start

Available Tools

1. sketchfab-search

Parameters:

• `modelId`: The unique ID of the Sketchfab model

3. sketchfab-download

Download a 3D model from Sketchfab.

Parameters:

• `modelId`: The unique ID of the Sketchfab model to download
• `format` (optional): Preferred format to download the model in (gltf, glb, usdz, source)
• `outputPath` (optional): Local directory or file path to save the downloaded file

Using with Cursor

1. Go to Cursor Settings -> MCP -> Add new MCP server

Add the following MCP config to your Claude Desktop configuration:

{
  "mcpServers": {
    "sketchfab": {
      "command": "node",
      "args": ["/path/to/build/index.js", "--api-key", "YOUR_API_KEY"]
    }
  }
}
