How to connect AI to Blender

Two ways: a browser extension, or an MCP server. Both reach the same Blender on your own machine.

In short

Blender Bridge connects an AI assistant to the Blender that is already open on your computer. You describe a scene in plain language, the assistant writes Blender Python, the code runs in your Blender window, and a screenshot of the result goes back to the assistant so it can see what it made and correct itself.

Nothing runs on our servers. The connection stays inside your machine and requires a pairing key.

What you need first

Blender — installed separately from blender.org. Blender Bridge does not bundle it and does not modify your installation.
The Blender Bridge application — it holds the connection between the AI and Blender.
An AI assistant that can write code. Any will do: you are not tied to one vendor, and you do not buy AI access from us.
Windows. The only supported system for now.

Choose how to connect

There are two ways, and you never have to switch between them. One is enough.

	Browser extension	MCP server
For	People who chat with an AI in a browser	People working in an AI agent or code editor
Where you type	In an ordinary AI web chat	In Claude Code, Codex, Cursor, VS Code and similar
What you do	Ask, then press run in the panel	Ask; the agent runs, looks at the result and continues
Better when	You want to see every step	You want the work delegated

In detail: connecting through the extension and connecting through MCP.

The common sequence

Install Blender if you do not have it.
Install the Blender Bridge application and open it.
Press Install add-on. The add-on appears in Blender the next time you start it.
Sign in. Sign-in opens in your browser; afterwards the application receives a pairing key.
Choose your door: install the browser extension, or copy the MCP registration from the application's settings into your agent.
Open Blender and leave it open. Ask the assistant for something simple and check that it appears in the scene.

How to tell it is working

The application shows two indicators: the HTTP bridge and the Blender server. Both must read Online. If the first is online and the second is not, Blender is closed or the add-on is disabled.

The simplest check: ask the assistant to create a cube. It should appear within a second or two, and the operation should show up in the bridge history.

Frequently asked questions

Does this replace learning Blender?

No, and promising otherwise would be dishonest. Blender Bridge removes the hands, not the knowledge: you no longer need to remember where a button lives or what an operation is called. But the better you understand what you want from a scene, the closer the result — describing the task stays with you.

Do I have to keep the application open all the time?

While you work through an AI, yes. The application is the connection: it takes the command and passes it to Blender. When you work in Blender by hand, it is not needed.

Does it work without an internet connection?

The link between the application and Blender does — it is entirely inside your machine. But the AI itself lives online, and signing in needs the network too. Without internet you are left with ordinary Blender.

Do I pay for the AI separately?

You get assistant access from its own provider, not from us. Most have free tiers that are enough to start. A Blender Bridge subscription neither includes nor requires AI access.

What happens to my scenes when the subscription ends?

They stay with you. They are ordinary Blender files on your own disk: we do not store them, encrypt them or switch them off. Only the link to the AI stops working.
