Quickstart
> **Note:** the PyPI package blender-mcp is now **mcp-for-blender**. Existing setups
> keep working — uvx blender-mcp still runs the server and **no config change is
> required**. New installs should use mcp-for-blender.
> What changed and why
**One command** sets up your AI apps and the Blender addon:
**macOS / Linux**
**Windows** (PowerShell)
Already have uv? Run uvx mcp-for-blender setup instead.
It installs uv if needed, finds the MCP clients on your machine (Claude Desktop, Claude Code, Codex, Cursor, VS Code, Devin Desktop/Windsurf, OpenCode, Antigravity), and lets you pick which to set up. Then it installs the Blender addon and enables it. Your existing config is kept: it only adds a blender entry and saves a .bak of each file it changes.
Then **fully quit and reopen your AI app** (on Windows, quit it from the system tray), open Blender, and ask it to build something. The addon starts its server when Blender opens.
Manual setup, in case the automatic setup doesn't work
Three steps: install uv, point your MCP client at the server, install the Blender addon.
**1. Install uv**
> **Warning:** Do not proceed before installing uv. Use the official installer — *not* pip install uv.
**2. Add the MCP server to your client**
Claude Desktop — Settings → Developer → Edit Config
Claude Code
Codex
Cursor / VS Code / OpenCode / Antigravity
See MCP Client Setup below for per-client instructions and one-click install buttons.
**3. Install the Blender addon**
Then in Blender: **Edit → Preferences → Add-ons** → enable **Interface: MCP for Blender**.
**4. Connect**
The addon starts its server when Blender opens. To check, press N in the 3D viewport → open the **MCP for Blender** tab (click **Start MCP Server** if it isn't running). That's it — ask Claude to build something.
> **Note:** Only run **one** instance of the MCP server (either Cursor or Claude Desktop), not both.

Features
| | |
|---|---|
| **Two-way communication** | Connect Claude AI to Blender through a socket-based server |
| **Object manipulation** | Create, modify, and delete 3D objects in Blender |
| **Material control** | Apply and modify materials and colors |
| **Visual verification** | Multi-angle, camera, wireframe, X-ray and animation-strip views, plus renders, so the AI checks its own work |
| **Code execution** | The AI writes Blender Python directly |
| **Asset & model generation** | Poly Haven assets, Sketchfab models, Poly Pizza low-poly models, and AI-generated 3D models via Tripo, Hyper3D Rodin and Hunyuan3D |
Premium
Generate AI 3D models (Hunyuan3D, Tripo, Hyper3D Rodin) straight into Blender without bringing your own API keys. More details
Components
The system consists of two main components:
1. **Blender Addon** (addon.py) — a Blender addon that creates a socket server within Blender to receive and execute commands
2. **MCP Server** (src/blender_mcp/server.py) — a Python server that implements the Model Context Protocol and connects to the Blender addon

Installation
Automatic setup
The quickest way is the one-line installer. It installs uv, configures your MCP clients, and installs and enables the Blender addon:
Already have uv? Run uvx mcp-for-blender setup instead. See Quickstart for what it changes. The rest of this section covers manual setup.
Prerequisites
- **Blender** 3.0 or newer
- **Python** 3.10 or newer
- **uv** package manager
Installing uv, per platform
**macOS**
