Lets an AI assistant like Claude control Blender 3D through a local add-on and server.

What it is

This is an unofficial bridge that lets an AI chat app, such as Claude, create and change objects in Blender. A small add-on runs inside Blender and a local MCP server passes commands between the AI and Blender. The README describes it as prompt-assisted 3D modeling and scene manipulation, and it is not made by the Blender Foundation.

Ask an AI assistant to create, modify or delete 3D objects in an open Blender scene
Apply and adjust materials and colors through a chat prompt
Have the AI check its own work using viewport and render views described in the README
Import assets from Poly Haven or Sketchfab, as listed in the features

Great for

Blender users who want to try describing scenes or objects in plain language
People experimenting with AI-driven 3D modeling workflows
Developers exploring the Model Context Protocol with a real application
Users who already use Claude, Cursor, VS Code or another supported MCP client

Not ideal for

Users who need fully predictable, hand-controlled modeling, since AI output may not match intent
People who do not want to install Python tooling (uv) and an add-on
Teams needing an officially supported Blender integration, since the README states it is third-party

How to get it

1
Install with a package manager
You'll need: Blender 3.0 or newer · Python 3.10 or newer · uv package manager
Run one-command setup (macOS / Linux)
curl -LsSf https://www.mcp-for-blender.com/install.sh | sh
Run setup if uv is already installed
uvx mcp-for-blender setup
Install the Blender add-on manually
uvx mcp-for-blender install-addon
2
Run it
- Run the installer or the setup command and pick your AI app
- Fully quit and reopen the AI app
- Open Blender and confirm the add-on is enabled in Preferences
- Press N in the 3D viewport and open the MCP for Blender tab to check the server
- Ask the AI assistant to build something in Blender
3
Get the most out of it
- Use the Visual verification features so the AI can check multi-angle and render views
- Add the server to more than one supported client, but run only one instance at a time, as the README advises
- Use the Asset and model generation integrations (Poly Haven, Sketchfab, Poly Pizza) for ready-made content
- Review the Environment Variables and Persistent API Credentials sections for optional configuration

Strengths

Connects many MCP clients through a documented setup and a guided setup command
Keeps existing config and saves a backup of each changed file, per the README
Open source under the MIT license with a large community following

Trade-offs

Some asset and AI model generation features depend on third-party services and API keys or a Premium offering
Output quality depends on the AI model and on how precisely the request is worded
Requires running a local server, so setup has several steps for non-technical users
