Overview

The Blender MCP Server connects Blender to Claude AI through the Model Context Protocol (MCP), allowing Claude to directly interact with and control Blender. It is listed as a third-party MCP server in the official Model Context Protocol repository.

The system consists of two main components:

Blender Addon (addon.py): A Blender addon that creates a socket server within Blender to receive and execute commands
MCP Server (src/blender_mcp/server.py): A Python server that implements the Model Context Protocol and connects to the Blender addon

Detailed Usage

execute_blender_code▶

Warning:

Use with caution in production environments as it allows running arbitrary code

Run arbitrary Python code in Blender from Claude.

use_mcp_tool({
  server_name: "blender",
  tool_name: "execute_blender_code",
  arguments: {
    code: "import bpy; bpy.ops.mesh.primitive_cube_add(size=2, location=(0, 0, 0))"
  }
});

create_object▶

Create 3D objects (e.g., cube, sphere) in the Blender scene.

use_mcp_tool({
  server_name: "blender",
  tool_name: "create_object",
  arguments: {
    type: "cube",
    size: 2,
    location: [0, 0, 0]
  }
});

modify_material▶

Apply or modify materials and colors for Blender objects.

use_mcp_tool({
  server_name: "blender",
  tool_name: "modify_material",
  arguments: {
    object_name: "Cube",
    material_name: "RedMaterial",
    color: [1, 0, 0, 1]
  }
});

inspect_scene▶

Get detailed information about the current Blender scene and objects.

use_mcp_tool({
  server_name: "blender",
  tool_name: "inspect_scene",
  arguments: {}
});

Installation

Prerequisites

Blender 3.0 or newer
Python 3.10 or newer
uv package manager (install via brew install uv on macOS)

Claude Desktop Integration

Add the following configuration to claude_desktop_config.json:

{
  "mcpServers": {
    "blender": {
      "command": "uvx",
      "args": [
        "blender-mcp"
      ]
    }
  }
}

Blender Addon Installation

Download the addon.py file from the GitHub repo
Open Blender > Edit > Preferences > Add-ons
Install and enable the "Interface: Blender MCP" addon

Model Context Protocol (MCP): Open Standard for AI Integration

The Model Context Protocol (MCP) is an open standard enabling AI systems to connect with diverse data sources, tools, and services, eliminating custom integrations for seamless interaction.

Redis MCP Server

Redis MCP servers enable AI models to interact with Redis databases, providing capabilities for key-value operations, caching, pub/sub messaging, and high-performance data structures.

MCP Architecture Overview

MCP (Model Context Protocol) features a distributed architecture enabling AI applications to communicate seamlessly with multiple data sources and tools through standardized interfaces.
