This MCP server connects Blender to Claude AI through the Model Context Protocol, enabling AI-assisted 3D modeling, scene creation, and manipulation with two-way communication between Claude and Blender.
Before installation, ensure you have:
Mac:
brew install uv
Windows:
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
Then add uv to your Windows user path:
$localBin = "$env:USERPROFILE\.local\bin"
$userPath = [Environment]::GetEnvironmentVariable("Path", "User")
[Environment]::SetEnvironmentVariable("Path", "$userPath;$localBin", "User")
⚠️ Do not proceed without installing UV first
addon.py file from the repositoryaddon.py file{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}
For Mac users: Go to Settings > MCP and add either as a global server or project-specific server:
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}
For Windows users: Go to Settings > MCP > Add Server with these settings:
{
"mcpServers": {
"blender": {
"command": "cmd",
"args": [
"/c",
"uvx",
"blender-mcp"
]
}
}
}
Install the MCP extension in VS Code first, then configure the blender-mcp server.
You can configure the Blender connection using these environment variables:
BLENDER_HOST: Host address for Blender socket server (default: "localhost")BLENDER_PORT: Port number for Blender socket server (default: 9876)Example:
export BLENDER_HOST='host.docker.internal'
export BLENDER_PORT=9876
Once connected, you'll see a hammer icon with tools for the Blender MCP in Claude's interface.
Here are some things you can ask Claude to do with Blender:
You can also provide reference images and ask Claude to create a Blender scene based on them.
Hyper3D's free trial key allows you to generate a limited number of models per day. If you reach the daily limit, you can wait for the next day's reset or get your own key from hyper3d.ai and fal.ai.
execute_blender_code tool allows running arbitrary Python code in Blender, which can be powerful but potentially dangerous. Always save your work before using it.To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "blender" '{"command":"uvx","args":["blender-mcp"]}'See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.json2. Add this to your configuration file:
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}3. Restart Claude Desktop for the changes to take effect
