MCP-Blender

What is MCP-Blender?

MCP-Blender is a Model Context Protocol server that connects Blender with Claude AI. It enables Claude to directly interact with and control Blender, allowing rapid, natural language‑based 3D modeling with support for parametric and relational design.

How to use MCP-Blender?

Install the UV package, clone the repository, and install the Blender add‑on (blender_addon.py) in Blender’s preferences. Then edit your Claude Desktop config (claude_desktop_config.json) to point to uvx with the argument blender-mcp, restart Claude, and verify the connection.

Key features of MCP-Blender

• Connects Blender with Claude via the Model Context Protocol.

• Executes temporary Python code inside Blender.
• Supports parametric and relational design workflows.
• Future support planned for CATIA and SolidWorks.

Use cases of MCP-Blender

• Rapid 3D prototyping using natural language commands.
• Parametric modeling controlled by conversational AI.
• Automating repetitive modeling tasks in Blender.
• Generating 3D assets from high‑level design descriptions.

FAQ from MCP-Blender

What are the system requirements?

Blender 3.5 or later, Claude AI, Python 3.10 or later, and the UV package manager are required.

How do I install the Blender add‑on?

Download blender_addon.py, open Blender, go to Edit → Preferences → Add‑ons → Install Add‑on, select the file, and enable “Interface: Blender MCP”.

Where does the server configuration live?

In the Claude Desktop config file (claude_desktop_config.json), which you open via Claude’s settings → Developer → Edit Config.

What security considerations exist?

The server can execute arbitrary Python code, which may be dangerous. Disable the Blender MCP add‑on when not in use.

Is this limited to Blender?

Yes, the current release is for Blender only. The README notes that MCP servers for CATIA and SolidWorks are planned for the future.
