Blender

You connect Blender with Claude AI using the Model Context Protocol, enabling Claude to directly interact with Blender for fast, natural 3D modeling. This MCP server enables parametric and relational design workflows, with future expansion to other CAD tools.

How to use

Install and run the MCP server locally, then connect your MCP client to the Blender MCP endpoint. You can use Claude AI as the client to drive Blender, issue modeling commands, and execute temporary code snippets within Blender to accelerate your design workflow. The server handles the communication between Blender and Claude, letting you create models, parameterize designs, and iterate rapidly.

How to install

Prerequisites you need before installing the Blender MCP Server.

Step 1 — Install the UV package and verify your setup.

pip install uv

uv --version
uvx --version

Check the installation path for uvx. If you are in a virtual environment, provide the full path to ensure the correct executable is used.

# 설치 경로 확인
where uvx

Step 2 — Install the Blender MCP Add-on.

# Blender Add-on 안내
# 1) blender_addon.py를 다운로드
# 2) Blender를 실행
#    Edit -> Preferences -> Add-ons -> Inrell Add-on -> blender_addon.py(다운로드 위치)
# 3) Interface: Blender MCP 체크박스 활성화

Step 3 — Configure Claude AI to use the Blender MCP server.

{
    "mcpServers":
    {
        "Blender":
        {
            "command": "D:\\Anaconda\\envs\\aria\\Scripts\\uvx.exe",
            "args": ["blender-mcp" ]
        }
    }
}

Additional steps and notes

After updating the claude_desktop_config.json, restart Claude AI to establish the connection with Blender. If Claude was running during changes, close Claude AI via the File menu and reopen it to apply the new MCP server settings.

Security considerations: Blender MCP may execute Python code within the integration. Only enable Blender MCP when you trust the connected client, and disable it when not in use to reduce potential risks.

Limitations and security considerations

Changes in Blender versions may affect MCP functionality. Ensure you are using Blender 3.5+ and a compatible Claude AI setup. Exercise caution with any code execution triggered from Claude, and deactivate the Blender MCP integration when not needed.

Notes

The Blender MCP integration is designed to support Model Context Protocol communication between Blender and Claude AI, enabling quick, natural modeling and parametric design workflows.
