Thingiverse MCP Server is a Model Context Protocol server that interfaces with the Thingiverse API to provide AI assistants the ability to search, browse, and retrieve 3D printable models. It supports features like model searching, category browsing, and random model discovery through Puppeteer's capabilities.

Thingiverse MCP Server

A Model Context Protocol (MCP) server that provides tools for interacting with the Thingiverse API, allowing AI assistants to search for, explore, and retrieve 3D printable models.

TypeScript Node.js

🌟 Overview

This MCP server wraps the Thingiverse API using Puppeteer to create a reliable interface that can be used by AI assistants. It provides tools to:

  • Search for 3D printable models
  • Get random 3D models
  • Browse categories
  • Get models from specific categories

🚀 Features

  • 🔍 Model Search: Search Thingiverse's database of 3D printable models using keywords
  • 🗂️ Category Browsing: Explore models by categories
  • 🎲 Random Models: Discover random 3D models from Thingiverse
  • 🌐 Complete API Access: Get detailed information about models, including descriptions, files, images, and more
  • 🤖 AI Assistant Integration: Designed to work with AI assistants through the Model Context Protocol

📋 Prerequisites

  • Node.js (v14 or higher)
  • npm or yarn
  • Thingiverse API token

🔧 Installation

  1. Clone the repository

    git clone <repository-url>
    cd thingiverse-mcp
    
  2. Install dependencies

    npm install
    
  3. Set up environment variables

    # Create development environment file
    cp .env.example .env.development
    # Create production environment file
    cp .env.example .env.production
    
  4. Configure API token

    • Get a Thingiverse App Token from the Thingiverse Developer Portal
    • Add your token to both .env.development and .env.production files:
      APP_TOKEN=your_api_token_here
      

🎮 Usage

Development Mode

npm run dev

This starts the MCP server in development mode with hot reload.

Production Mode

npm run build
npm start

Or use the shorthand:

npm run prod

🔗 Integrating with Claude Desktop

To add this MCP server to Claude Desktop and enable Thingiverse browsing capabilities:

  1. Start the MCP server Make sure your server is running locally or on a remote host that Claude Desktop can access.

  2. Open Claude Desktop settings

    • Launch Claude Desktop
    • Click on your profile picture or icon in the top right
    • Select "Settings" from the dropdown menu
  3. Navigate to Extensions settings

    • In the Settings sidebar, click on "Extensions"
    • Select "Add Custom MCP"

4.1 Configure the MCP connection

  • Name: Thingiverse MCP (or any name you prefer)
  • URL: Enter the URL where your MCP server is running (e.g., http://localhost:3000 for local development)
  • Click "Add MCP"

4.2 Alternative Configure the MCP connection

  • You first need to build the project and provide your full path C:/.../Thingiverse/dist/index.js
"thingiverse": {
   "command": "node",
   "args": [
     "YOUR_CUSTOM_PATH/Thingiverse/dist/index.js"
   ]
 }
  1. Enable the MCP

    • Toggle the switch next to your newly added Thingiverse MCP to enable it
    • Claude Desktop will attempt to connect to your MCP server
  2. Verify connection

    • Start a new conversation with Claude
    • Type "Can you help me find some 3D models on Thingiverse?"
    • Claude should now be able to use the Thingiverse tools to search and browse models
  3. Troubleshooting

    • If Claude cannot connect to your MCP server, check that:
      • The server is running and accessible from Claude Desktop
      • The correct URL is configured in Claude Desktop settings
      • Your API token is valid and properly configured in the server

Usage Examples with Claude

Once connected, you can ask Claude to:

  • "Find me some 3D printable smartphone stands on Thingiverse"
  • "Show me some popular 3D models in the gadgets category"
  • "Get me a random 3D model from Thingiverse"
  • "What categories of 3D models are available on Thingiverse?"

🧠 Available Tools

The server exposes several tools that can be used by AI assistants:

get-things

Searches for 3D models based on a search term.

Parameters:

  • term: Search term (required)
  • categoryId: Optional category ID to narrow down search

get-random-thing

Retrieves random 3D models from Thingiverse.

get-categories

Fetches all available categories from Thingiverse.

get-random-thing-from-category

Gets random 3D models from a specific category.

Parameters:

  • categorySlug: Category slug (required)

🔍 How It Works

The server uses Puppeteer with Stealth plugin to interact with the Thingiverse API. This approach:

  1. Handles authentication via API tokens
  2. Makes requests to various Thingiverse endpoints
  3. Parses and returns the data in a structured format
  4. Exposes endpoints as MCP tools that can be called by AI assistants

⚙️ Development

Environment Configuration

The server uses different environment files for development and production:

  • .env.development - Used when running in development mode
  • .env.production - Used when running in production mode

Testing

Run the test suite with:

npm test

Linting and Formatting

# Run ESLint
npm run lint

# Fix ESLint errors
npm run lint:fix

# Format code with Prettier
npm run format

📝 Notes for Deployment

When deploying to production:

  1. Ensure your .env.production file contains a valid Thingiverse API token
  2. The build process will embed this token in the compiled code
  3. Use npm run prod to build and start the production server
