Intangible

Intangible Agents & MCP

Your agent builds the set. You direct it.

Use Claude, ChatGPT, Gemini, Grok, Cursor and other AI agents in one 3D creative canvas. Describe a scene, watch it build in Studio and stay in control, with no Blender to wrangle.

What it is

What is Intangible MCP?

Intangible is an all-in-one 3D creative canvas that runs in your browser. Intangible MCP is its remote Model Context Protocol (MCP) server. Connect the AI models and agents you already use, and they build 3D scenes, frame shots and render images in Studio while you direct.

Many models, one canvas

Claude, ChatGPT, Gemini, Grok, Cursor, open models and any MCP client with remote servers.

Speed and control

The agent builds the scene fast. You adjust anything on screen, by hand or by prompt.

No native apps to wrangle

Studio runs in the browser. No Blender, no plugins, no API key. Sign-in is OAuth.

How it works

Connect once, then describe.

01

Add one URL

Paste the server URL into your agent’s connector or MCP settings.

02

Approve access

Sign in to your Intangible account and click Approve access. Agents need Explorer or above, which starts with a free trial.

03

Describe the scene

Keep one Studio tab open. Say what the space is, what’s in it and how things relate.

Start with one room or zone, then direct one change per message. No brief yet? Open with a loose idea, and the agent asks a round of questions before it builds.

Build, Compose, Visualize

The same three modes, driven by an agent.

01 BUILD

Stand up the scene

The agent places 3D assets in Build Mode to create a virtual set from your brief.

02 COMPOSE

Frame the shots

Ask for beauty shots, or a set of them. They show up in Compose Mode as a named list.

03 VISUALIZE

Finish the image

Ask to render the framed shots with art direction. The agent hands off to Visualize Mode.

Keep your chat and Studio side by side to watch the scene build. Objects land roughly right, so you nudge them into place on screen.

Under the hood

3D scenes as code.

Intangible treats a 3D design as code. Your agent writes code, including math and procedural layouts, to build the scene.

Math and procedural layouts

One piece of code can lay out a whole room or a full grid of desks.

Runs safely in a sandbox

Intangible’s MCP server runs the code in a sandbox, against your live scene.

Quick and at scale

Scenes build quickly, because one piece of code does the work of dozens of steps.

You still direct in plain language. The agent writes the code.

Install

Connect your agent.

For AI agents

Setting up Intangible for your user.

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

Sign-in
OAuth with dynamic client registration. No API key, client ID or secret.
Before building
Exactly one Studio tab open. Confirm it with get_or_set_studio_target.
First call
load_skill('intangible-agent-orientation')
Transport
Streamable HTTP. Remote only, with no local mode.
Building
Write code. Call load_skill('intangible-scene-scripting') and follow it.
Deleting
Never delete scene content unless the user asks.

FAQ

Questions about Intangible MCP.

Which AI agents work with Intangible?

Claude, Claude Code, ChatGPT, Codex, the Gemini app, Gemini CLI, grok.com, Grok Bot, Grok Build, the Muse app, Muse Code, Cursor and Perplexity, plus open models such as NVIDIA Nemotron through Grok Build. Any MCP client that supports remote servers with OAuth sign-in can connect.

Do I need Blender or other 3D software?

No. Intangible Studio runs in your browser, and your agent builds the scene there. You only need the AI app or agent you already use.

Is Intangible free?

Yes, to start. The Free plan needs no card and includes 150 credits to explore 3D scenes and images. Connecting an agent over MCP needs Explorer, Business or Enterprise. Explorer and Business start with a free trial. Rendering in Visualize uses credits. See intangible.ai/pricing.

Do I need an Intangible account?

Yes, on Explorer, Business or Enterprise. The Free plan doesn't include agent access. Your agent builds in your Intangible projects, so you sign in when you approve access. Sign up at studio.intangible.ai and start a free trial.

Do I need an API key?

No. You add the server URL, then approve access on an Intangible page. Sign-in is OAuth.

Why does the Gemini app have no Custom button?

You're signed in with a work or school Google account. Google allows custom connected apps only on personal Google accounts, and a Workspace admin can't turn it on. Use a personal Google account, or use Gemini CLI, which works with work accounts.

What happens with two Studio tabs open?

The agent can build in the wrong project, or stop because it can't tell which one you mean. Keep one Studio tab open while the agent works.

A connection that worked yesterday stopped. What now?

The sign-in expired. Sign in to Intangible again from your app. In Codex, run codex mcp login intangible.

Can I run the Intangible MCP server locally?

No. The server is hosted at https://mcp.intangible.ai/mcp. Your agent reaches it over the network and signs in with OAuth.
