Mixos and ChatGPTChatGPT connector · Studio · Mold · Paint
Build 3D scenes by asking ChatGPT.
Connect Mixos to the ChatGPT you already use. Describe an object, a lighting setup or a camera move, and it happens in your open tab — 450+ commands across Studio, Mold and Paint, on your own ChatGPT plan, with no API key to paste.
Things to ask for
- “Build a low table with four tapered legs and put a bowl on it”
- “Add a three-point light rig and warm the key light”
- “Give everything on the floor a brushed-steel material”
- “Frame the hero object from a low angle and render a still”
- “Animate the camera orbiting the scene over four seconds”
- “What's in this scene, and what is selected right now?”
Setup
Four steps, once.
ChatGPT has no one-click install for custom connectors, so the first two steps are done by hand. After that it is just a conversation.
Turn on Developer mode
- 1.Open ChatGPT on the web and go to Settings.
- 2.Open Security and login.
- 3.Switch on Developer mode.
Without this there is no way to add a custom connector — the button does not appear. On a Business or Enterprise workspace an admin may need to allow it first.
Add Mixos as a connector
- 1.Go to chatgpt.com/plugins.
- 2.Press the + button.
- 3.Name it Mixos and paste the URL below.
- 4.Save, then press Connect and approve it (step 3).
https://www.mixos.io/api/mcpApprove what it may do
Mixos asks you to sign in and shows exactly what the connection is allowed to do. You choose, and you can change it later by reconnecting.
- See your Studio projects and scenes, and read their contents
- Create and change scenes in your Studio library
- Generate materials, images and video with AI — this spends your Mixos AI credits. Leave it unticked and nothing can be spent.
- See your plan, credit balance and storage use
ChatGPT lists these as tick boxes in the connector’s own setup too, so you can turn the AI generation permission off there before you ever reach this screen. Either place is enough — the connector cannot spend credits unless it is ticked in both.
Connect a scene
- 1.Open a scene in Mixos Studio (or Mold, or Paint).
- 2.Press Connect to Claude in the top bar — one connection serves both assistants, so there is no separate ChatGPT button.
- 3.Press Connect. That tab is now the one your assistant drives.
What ChatGPT can do
Every command in three apps, with your work in front of it.
The connector exposes the same command layer the apps themselves run on, so there is no second, smaller feature set: 402 in Studio, 34 in Mold and 36 in Paint. It reads your document before acting and reports what actually happened afterwards — including when the app clamped or refused a request.
Model
Primitives, booleans, extrusions, bevels, modifiers and the half-edge editing tools, on the selection you have.
Assemble
Create, name, parent, duplicate and place objects; snap them to each other and to the floor.
Material
Assign PBR materials from the library or describe one; set colour, roughness, metal, emission.
Light and camera
Three-point rigs, HDRI environments, area and IES lamps; frame shots and set lenses.
Animate
Keyframes, camera paths, rigging and the motion library, on a timeline it can scrub.
Render and see
Render stills, take viewport captures it can look at, and query anything in the scene.
Sculpt
In Mold: brushes and strokes, masks and face sets, dynamic remesh, multiresolution levels, booleans and shell extraction.
Paint
In Paint: the layer stack — add, reorder, rename, blend modes, opacity, visibility and text layers.
Built to be trusted with your work
You stay in the loop, by design.
Deletes ask first, in the tab
Any command that deletes or overwrites stops in Mixos and names the object before anything happens. That prompt is ours, so it happens whatever your client confirms on its own side. Everything else is an ordinary undo step.
Only the tab you connected
Connecting is a deliberate press in one tab, never automatic on sign-in. Close the tab and the session ends; leave it open and it ends itself after twelve hours.
Credits are a separate permission
Generating a material, a still, a video or a logo mark spends Mixos AI credits, so it is its own line on the consent screen. Leave it unticked and every one of those is refused — the connector cannot spend anything.
Revoke in one click
Account → Connected apps lists every client with access and when it last used it. Disconnecting kills every token immediately, and leaves your other assistants working.
Billing, teams and account settings are not reachable through the connector at all — those routes accept only a signed-in browser session. Read more on the security page.
One ChatGPT quirk worth knowing
ChatGPT reads the list of available tools once, when the connection is made. Mixos widens that list as your document grows — add a cloner and the cloner tools appear — so a long conversation can be working from the list it was handed at the start. Open the connector, press Refresh, then start a new chat. You never have to remove and re-add it, and inside a conversation it can still search for anything that is not listed.
Questions
- Does this use my Mixos AI credits?
- Not unless you grant the generate permission. Modeling, lighting, cameras, rendering and queries run in your browser and cost nothing — including applying a material you already have. What spends credits is asking AI to MAKE one: a generated material, a still, a video, or a logo mark. Those cost exactly what they cost in the app, and the connector is refused every one of them unless you tick that permission when you connect. There are two places to refuse it: ChatGPT lists the permissions as tick boxes when you add the connector, and the Mixos approval screen lists them again on its own line. Turning it off in either one is enough.
- Which ChatGPT plans work?
- Custom connectors are available on ChatGPT Plus, Pro, Business, Enterprise and Edu, on the web. The model runs on your own ChatGPT subscription, so Mixos never asks for an API key and never meters the conversation. On a Business or Enterprise workspace an admin may need to allow custom connectors before the setting appears.
- ChatGPT can’t see the tools I just unlocked
- ChatGPT reads the tool list once, when the connection is made, and does not re-read it on its own. Mixos widens that list as your document grows — add a cloner and the cloner tools become available — so a long conversation can be looking at the list it was handed at the start. Open the connector, press Refresh, then start a new chat. You do not have to remove and re-add it. Inside a conversation, asking ChatGPT to search for what it needs still reaches everything.
- Can I use Claude and ChatGPT at the same time?
- Yes. They are separate connections with separate permissions, and both drive the same connected tab — whichever app you last pressed Connect in. Revoking one in Account → Connected apps leaves the other working. There is no need to disconnect one to use the other.
- Does an app need to be open?
- For changes, yes — commands run in a Studio, Mold or Paint tab you have pressed Connect in, because your document lives in your browser. Whichever app you connect is the one whose tools ChatGPT is handed: connect Mold and it gets the sculpting commands, not the scene graph. ChatGPT can still answer “what can Mixos do” and search every command in all three apps with nothing open. If no tab is connected, it tells you that instead of guessing.
- Can ChatGPT delete my work?
- Not silently. Any command that deletes or overwrites part of a scene stops in the Mixos tab and asks you first, with the object named — that prompt is ours, and it happens whatever your client decides to confirm on its side. Approving one delete does not approve the next. And every change is a normal undo step.
- How do I disconnect?
- From the Mixos top bar to end the current tab’s session, or from Account → Connected apps to revoke ChatGPT’s access entirely. Revoking is immediate and kills every token that connection held. Signing out of Mixos alone does not disconnect it.
- ChatGPT can’t add the connector
- Two things account for nearly all of it. First, Developer mode has to be on — without it there is no button to add a server at all. Second, use the URL exactly as written here — https://www.mixos.io/api/mcp — with https and the www; a different spelling of the address is a different server. If an approval page says the link expired, it was older than ten minutes; start again from ChatGPT and it will open a fresh one.
- Is this the same as the assistant inside Studio?
- Same commands, opposite billing. The in-app assistant uses a key you paste; the connector uses the ChatGPT you already pay for, with its own memory and files alongside your scene.
