Intangible

Intangible MCP · Beta

Your agent builds the set. You direct it.

Intangible speaks MCP, so any agent that does can drive it - Claude Code, Claude Desktop, ChatGPT and the rest. Describe 3D scenes, shots and visuals in your client app. Watch it work side-by-side in a browser with Intangible. Take the wheel to fine tune results.

The same three modes, driven by an agent.

01 Build

Stand up the scene

The agent places 3D assets in Intangible’s Build Mode, to create a virtual set based on your brief. Reasoning in 3D is (still) slow for AI so grab a coffee while it works.

02 Compose

Frame the shots

Ask for specific beauty shots (or a set). The agent sets cameras and takes shots that show up in Intangible’s Compose Mode as a named list.

03 Visualize

Finish the image

Ask to turn the framed shots into rendered images with art direction details. The agent hands off to Visualize Mode and generates them. Video generation coming soon.

Your agent operates Intangible in a browser

You brief the agent in your LLM client; the 3D set takes shape in a browser window with Intangible. Keep both in view and you can watch the scene build.

It gets you 80% there, on purpose

3D placement is hard for an LLM. Expect objects to land roughly right so you can nudge them into place on screen (faster and fewer tokens than describing it to a prompt box).

MCP Beta Setup

Connect your client.

One remote server, and any agent that speaks MCP can use it. Steps for the three most common clients are below, copy-paste ready.
This Beta release launches with Build-Compose-Visualize modes available to your agents. We’ll open up more functionality in Intangible to agents in the coming weeks.

Server URL https://mcp.intangible.ai/mcp

Before you start

  • Claude Desktop installed and signed in.
  • On a Team or Enterprise plan, an Owner has already added the connector for the organization. Members cannot add one themselves, and without it the Add custom connector button will not appear.
  • Your Intangible login ready. Sign-in opens in the browser.
  • An Intangible project. You do not need it open first - the agent will prompt you when it needs one.
01

Open connector settings

In Claude Desktop: Settings › Connectors, then Add custom connector at the foot of the section.

On Team and Enterprise plans this is an Owner-only step, done once for the whole organization at Settings › Organization settings › Connectors. Everyone else picks up at step 3.

02

Name it and paste the URL

Name: Intangible. Remote MCP server URL:

https://mcp.intangible.ai/mcp

Click Add.

03

Connect and sign in

Click Connect on the Intangible connector. Your browser opens, sign in to Intangible and approve. Back in Desktop, the connector shows Connected.

04

Enable it in your chat

In a new chat, open the tools menu (the sliders icon under the message box) and make sure Intangible is toggled on.

Before you start

  • A Business, Enterprise or Edu workspace. Personal plans can attach the connector but only get read-only access to it, which is not enough to build a scene.
  • Developer mode switched on for your workspace.
  • Your Intangible login ready. Sign-in opens in the browser.
  • An Intangible project. You do not need it open first - the agent will prompt you when it needs one.
01

Turn on developer mode

An owner or admin enables it for the workspace first: Workspace Settings › Permissions & Roles › Connected Data, then the developer mode toggle. Each user then switches it on for themselves at Settings › Apps & Connectors › Advanced settings.

If you cannot see the toggle at all, the workspace has not allowed it yet.

02

Create the connector

Go to Settings › Apps & Connectors and click Create. Name: Intangible. Server URL:

https://mcp.intangible.ai/mcp

Transport is Streamable HTTP. Authentication is OAuth. ChatGPT will warn you that custom connectors are not verified by OpenAI, which is expected here.

03

Sign in

Your browser opens. Sign in to Intangible and approve. The connector comes back showing its tool list.

04

Publish it to the workspace

An owner publishes from Workspace Settings › Apps › Drafts. Review the write actions on the way through. Once published it appears in every member’s Apps list, labelled custom, and each person authenticates for themselves.

On Business, a published app cannot be edited. Changing the tool list means recreating and republishing it.

05

Enable it in your chat

Start a new chat, open the apps menu under the message box, and switch Intangible on. Confirm the tool list loaded. If it is empty, open the connector in settings and choose Refresh.

ChatGPT asks you to approve each write action before it runs, so expect a confirmation prompt the first time the agent places anything.

Before you start

  • Claude Code installed and signed in. Run claude once first.
  • Your Intangible login ready. Sign-in opens in the browser.
  • An Intangible project. You do not need it open first - the agent will prompt you when it needs one.
01

Add the server

Any directory works. --scope user makes it available in every project, not just one folder.

claude mcp add --transport http --scope user intangible https://mcp.intangible.ai/mcp
02

Verify it registered

claude mcp list

You should see:

intangible: https://mcp.intangible.ai/mcp (HTTP) - ! Needs authentication

“Needs authentication” is expected at this point.

03

Restart Claude Code

Fully quit any running session and start it again with claude. New servers only appear after a restart.

04

Authenticate

Inside Claude Code, run the command below, select intangible, then sign in and approve in the browser window that opens.

/mcp

Status flips to Connected and the tools load. Tokens are handled for you, there are no API keys.

The wrong URL is the single most common cause of failure, so copy it from the field above rather than retyping it. Claude Code, Claude Desktop and ChatGPT each keep their own MCP config, so installing in one does not carry over to the others.

Then say hello

Send the agent a first message. hello works. So does a full brief: build me a medieval street with 10 buildings. Before it places a single vertex, the agent tells you how the collaboration works: the three Studio modes it works through, roughly how long a build takes, what it handles, and what stays in your hands.

The shape of a session. You brief the agent in your client; the scene is built and finished in Studio. The agent takes on the slow parts, standing up a large 3D scene, composing shots against it, setting camera moves. A large scene takes minutes to build and minutes more to shoot. The viewport stays empty for the first couple of minutes while the agent searches for assets, which is normal.

What you finish yourself. The agent gets a scene about 80% of the way there and hands back a named list of placements to nudge. Objects land close to right rather than exactly right, and moving one on screen yourself is faster and more accurate than describing it to a prompt box. The split is deliberate.

One tip from watching people use this: once the project is open, put the Studio window and your client side by side. The build lands in Studio while the conversation runs in the client.

If something goes wrong

“intangible” is missing from /mcp or the connector list

Claude Code: restart it fully. Servers added while a session is running don’t appear until the next launch. Then check that claude mcp list shows the entry.

Claude Desktop: quit and reopen the app, then check Settings › Connectors. If the connector isn’t there, re-add it from step 1.

Authentication loops or fails in the browser

Finish the sign-in in the browser tab that opened, then return to your client. If the tab never opened, pop-ups may be blocked for the auth window.

Still stuck: remove the server and start over. A stale token from a previous attempt is the usual cause.

Connected, but the agent says it can’t find my project

The agent asks you to open a project when it needs one, so follow the prompt it gives you. If you have already opened one at studio.intangible.ai, bring that tab into focus and ask the agent to try again by giving it the project URL - if it only just loaded, give it a few seconds to register.

ChatGPT connects and lists the tools, then refuses to place anything

This is a plan limit, not a setup mistake. Nearly every Intangible tool writes to your scene, and OpenAI is rolling out write actions for custom connectors on Business, Enterprise and Edu only. On personal plans the connector attaches and lists the tools, then declines to write.

If you are on a personal plan, use Claude Code or Claude Desktop instead.

I want to remove it and start over

Claude Code: claude mcp remove intangible

Claude Desktop: Settings › Connectors › Intangible › Remove. Then repeat the steps for your app from the top.

Say hello and watch it build.

Two minutes of setup, then a brief. The agent stands up the scene, you finish the shot.
