Quick Start
# macOS
brew install uvAdd to Claude > Settings > Developer > Edit Config > claude_desktop_config.json:

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

Installation
Prerequisites
| Requirement | Minimum version |
|---|---|
| Blender | 3.0 |
| Python | 3.10 |
| uv | Latest |
Install uv:
macOS
brew install uvWindows
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"Add to PATH (restart your client after):
$localBin = "$env:USERPROFILE\.local\bin"
$userPath = [Environment]::GetEnvironmentVariable("Path", "User")
[Environment]::SetEnvironmentVariable("Path", "$userPath;$localBin", "User")Linux
curl -LsSf https://astral.sh/uv/install.sh | shDo not use
pip install uvβ it may not create theuvxcommand.
uvx not found by your client
GUI clients don't inherit your terminal PATH. Get the full path:
which uvx(macOS/Linux) orwhere uvx(Windows)- Use it as
"command"in your config - Windows:
"command": "cmd", "args": ["/c", "uvx", "blender-mcp"] - Fully quit and relaunch your client after any config change

Connection issues
- Confirm the addon server is running in the BlenderMCP sidebar
- Do not run
uvxmanually β the client starts the server - First command often fails; try again
spawn uvx ENOENT
which uvx # macOS / Linux
where uvx # WindowsUse that full path as "command" in your config.
Timeout / complex operations
Break the request into smaller sequential prompts.
Python version conflicts
"args": ["--python", "3.11", "blender-mcp"],
"env": { "UV_PYTHON_PREFERENCE": "only-managed" }Clear cache: uv cache clean blender-mcp && uvx --refresh blender-mcp
Still broken?
Restart your MCP client and the Blender server.
