Overview

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.
