This Python-based server connects Blender to Claude AI through the Model Context Protocol (MCP), enabling AI-assisted 3D modeling and scene creation. With BlenderMCP, Claude can directly control Blender to create objects, apply materials, and manipulate scenes based on natural language instructions.
Install uv based on your operating system:
Mac:
brew install uv
Windows:
powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
set Path=C:\Users\nntra\.local\bin;%Path%
For other systems, check the uv installation guide.
To configure Claude for Desktop:
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}
Mac Users:
.cursor/mcp.json
in your project root{
"mcpServers": {
"blender": {
"command": "uvx",
"args": [
"blender-mcp"
]
}
}
}
Windows Users:
{
"mcpServers": {
"blender": {
"command": "cmd",
"args": [
"/c",
"uvx",
"blender-mcp"
]
}
}
}
⚠️ Important: Run only one instance of the MCP server (either on Cursor or Claude Desktop), not both.

fileOnce connected, you'll see a hammer icon in Claude with tools for the Blender MCP. You can now ask Claude to:
Here are some examples of what you can ask Claude to do:
Hyper3D's free trial key allows a limited number of model generations per day. When the limit is reached, you can wait for the next day's reset or obtain your own key from hyper3d.ai and fal.ai.
The system uses a JSON-based protocol over TCP sockets for communication:

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 > MCP and click "Add new global MCP server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"cursor-rules-mcp": {
"command": "npx",
"args": [
"-y",
"cursor-rules-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 explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
