Connect ChatGPT (Connectors & MCP)
Add 3D AI Studio to ChatGPT as a custom MCP connector in developer mode, sign in, and generate textured 3D models and images right inside your ChatGPT chats.
ChatGPT cannot create 3D models on its own. With the 3D AI Studio connector added, it can: you ask for a model in the chat, the generation runs on 3D AI Studio, and a real textured mesh with downloadable files comes back.

What you need
- A 3D AI Studio account on a paid plan.
- A ChatGPT plan that supports custom connectors. Availability depends on your ChatGPT plan and, for Business and Enterprise workspaces, on what your admin allows.
- The connector URL:
https://mcp.3daistudio.com/mcp
Menus look different? ChatGPT renames and moves its connector settings often, so the steps below can go out of date quickly. Look for Connectors, Apps, or Developer mode in Settings, or simply ask ChatGPT itself. It usually knows the current way (turn on web search):
How do I add a custom MCP connector in ChatGPT right now? I want to connect 3D AI Studio:
https://mcp.3daistudio.com/mcp (OAuth sign in, no API key).
Use https://docs.3daistudio.com/mcp-setup.md for the details and walk me through the exact steps for my plan.Setup
Open the connector settings
In ChatGPT on the web or desktop, open Settings → Connectors (in some versions: Apps & Connectors).
If you do not see a Create button, open Advanced settings in the same section and turn on Developer mode. ChatGPT requires it for custom connectors on some plans.
Create the connector
Click Create and fill in:
| Field | Value |
|---|---|
| Name | 3D AI Studio |
| Description | Generate 3D models and images (optional) |
| MCP server URL | https://mcp.3daistudio.com/mcp |
| Authentication | OAuth |
Confirm that you trust the application if ChatGPT asks, then click Create.
Sign in and authorize
A 3D AI Studio page opens:
- Sign in with your 3D AI Studio account.
- Review what ChatGPT will be able to do.
- Under Use credits from, keep Personal or choose a team.
- Click Authorize.
Use it in a chat
Start a new chat, open the + or tools menu in the message box, and select 3D AI Studio (with Developer mode, it is listed under the developer tools). Then ask:
"Make a three headed wolf statue I can 3D print."
Check that it worked
Ask ChatGPT: "Use 3D AI Studio to check my credit balance." It should call the connector and answer with a number. The connection also appears under Connected Apps in Settings → AI Assistants (MCP) on 3D AI Studio.
What it looks like in ChatGPT
Name the tool in your request. Say "use 3D AI Studio to make this 3D". Otherwise ChatGPT tends to reach for its own built in image generator first.
- ChatGPT starts the generation and checks on it until it is finished. 3D models take 1 to 5 minutes; images take seconds.
- Depending on your ChatGPT version, the finished result shows as a card or as a link. Either way, the model is saved to your dashboard, where you can view it in 3D and download it in any format.
- To use your own image, ChatGPT gives you an upload card or a link to an upload page. See Images & Uploads.
ChatGPT specific fixes
| Problem | Fix |
|---|---|
| No Create button under Connectors | Turn on Developer mode under Advanced settings, or check that your ChatGPT plan or workspace allows custom connectors |
| ChatGPT answers without using 3D AI Studio | Select 3D AI Studio from the tools menu in the chat, or say "use 3D AI Studio to..." |
| ChatGPT asks you to connect again | Open Settings → Connectors, select 3D AI Studio and connect again |
| Creating the connector fails | Check the URL is exactly https://mcp.3daistudio.com/mcp and that authentication is set to OAuth |

Frequently Asked Questions
Not by itself. ChatGPT has no 3D generation engine, so on its own it can at best write code for simple shapes. Connected to 3D AI Studio, it can generate real, textured 3D models with downloadable GLB, FBX, OBJ, STL, USDZ and 3MF files. For the full comparison of what works, see Can ChatGPT create 3D models?
No. ChatGPT signs in to 3D AI Studio through a normal login page (OAuth). No key is created or stored.
It uses the same AI models, the same credits and the same dashboard as the website. The difference is that you ask for things in your ChatGPT conversation instead of using the website's tools.
Claude
Add 3D AI Studio as a custom connector in Claude on the web or desktop app, then generate textured 3D models and images in chat with a built-in 3D viewer.
Claude Code
Add the 3D AI Studio MCP server to Claude Code with one claude mcp add command, sign in with /mcp, and generate 3D models and images from your terminal.
