I Gave AI Access to Blender. Here's What It Built

Hello, I am Rijul, and I am developing LiveReview - an AI code review tool designed for critical business systems. Please star the project to support developers in discovering it, giving it a try, and providing feedback to enhance the product. I have observed that MCPs are employed for various purposes. Have you considered their potential applications in software like Blender? Let me demonstrate.

This repository contains the necessary files: https://github.com/ahujasid/mcp-for-blender. This plugin enables control of Blender using any desired LLM. You can provide prompts, and Blender will respond appropriately. Installing the plugin is straightforward, as outlined in the README.

Step 1: Install UV. For macOS, use 'brew install uv'; for Linux, execute 'curl -LsSf https://astral.sh/uv/install.sh | sh'; and for Windows, run PowerShell command 'powershell -c irm https://astral.sh/uv/install.ps1 | iex'.

Step 2: Add the MCP server to your client. In Claude Desktop, configure the server with the command 'uvx mcp-for-blender'. For Claude Code, utilize 'claude mcp add blender uvx mcp-for-blender'. OpenCode users should execute 'codex mcp add blender -- uvx mcp-for-blender'. For Blender's OpenCode implementation, use '{ "mcp": { "blender-mcp": { "type": "local", "command": ["uvx", "mcp-for-blender"], "enabled": true, "environment": { "BLENDER_HOST": "localhost", "BLENDER_PORT": 9876 } } } }'.

Step 3: Install the Blender add-on using 'uvx mcp-for-blender install-addon'. Step 4: Navigate to Blender → Edit → Preferences. Step 5: Click Add-ons and enable MCP for Blender. Step 6: Connect the MCP server within Blender by pressing N. The following will appear on the screen. Click the MCP for Blender tab and ensure the server is connected. Under Asset Libraries, check Poly Haven, a free library of commercial-useable high-quality HDRIs, textures, and 3D models.

Now, let us explore the possibilities of Blender with AI. Here is a default Blender scene featuring a cube, light, and camera. We can inquire about the current scene, and the AI will accurately describe it. Now, let us put the AI to work. I will ask it to create a simple room. The instructions are clear: delete the default cube and create a room with a floor and four walls, approximately 5x5 meters in size and 3 meters tall. The AI executes the task, resulting in a basic room.

Next, let us create a more complex scene. I will prompt the AI to build a striking low-poly floating island. The steps include clearing the default scene, creating a floating island base using a deformed icosphere or cube with noise-based displacement, adding a simple low-poly tree off-center, scattering 4-6 small rocks with varied scale and rotation, and applying Poly Haven textures to achieve a grass/moss top layer and rock/stone bottom layer.

The AI executes this complex set of instructions, producing an impressive low-poly floating island scene in Blender.
