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

curl -LsSf https://www.mcp-for-blender.com/install.sh | sh

Windows (PowerShell)

irm https://www.mcp-for-blender.com/install.ps1 | iex

From Command Prompt instead: powershell -c "irm https://www.mcp-for-blender.com/install.ps1 | iex"

Prefer not to run a script, or Windows Defender blocked it? Install uv with winget, open a new terminal, then run setup:

winget install --id=astral-sh.uv -e
uvx mcp-for-blender setup

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.

Three steps: install uv, point your MCP client at the server, install the Blender addon.

1. Install uv

# macOS
brew install uv

# Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows
winget install --id=astral-sh.uv -e
# or, with uv's installer
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Warning: Do not proceed before installing uv. Use the official installer — not pip install uv.

2. Add the MCP server to your client

{
    "mcpServers": {
        "blender": {
            "command": "uvx",
            "args": ["mcp-for-blender"]
        }
    }
}

claude mcp add blender uvx mcp-for-blender

codex mcp add blender -- uvx mcp-for-blender

See MCP Client Setup below for per-client instructions and one-click install buttons.

3. Install the Blender addon

uvx mcp-for-blender install-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.
