How to Use MCP to Model Your Home From an AI Image in Blender

Step 1: Create or choose your AI image

Generate a house with an image AI, or use a real photo. A clear three-quarter view works best because it shows two sides. Remember that AI images can contain impossible details, so expect to make decisions as you model.

Setting Up Blender MCP

Install the connection once, then enable it inside Blender.

Step 2: Install the connection

The project offers one command that sets up your AI apps and the Blender addon. Install uv using its official installer first, and check the project's README for the current instructions.

uvx mcp-for-blender setup

# Or set things up separately, for example with Claude Code:
claude mcp add blender uvx mcp-for-blender
uvx mcp-for-blender install-addon

Step 3: Turn on the addon in Blender

If you installed the addon separately, go to Edit > Preferences > Add-ons and enable MCP for Blender. Then press N in the 3D viewport, open the MCP for Blender tab and click Start MCP Server if it isn't already running.

Building the House With Blender MCP

Work in stages, checking the model after each request. Small requests are easier to correct than big ones.

Step 4: Ask for simple massing first

Attach your image and ask for basic shapes before any detail. Give real dimensions if you have them. Otherwise, name a door height for the AI to scale from. Starting with blocks makes proportions easy to correct.

Using the attached house image as reference, create a new scene and model
simple massing only: main volume, garage and gabled roofs, in meters,
using a 2.1 m door height for scale. Don't add detail or materials yet.
Name every object, then show me the result.

Step 5: Add openings and details

Once the proportions look right, add details in small requests, such as porch posts, windows and doors. Check each step. Small requests are easier to fix, and big ones are more likely to time out or go wrong.

Add the front porch with five timber posts, then window and door openings
matching the reference. Keep everything on named collections.
Don't change the massing.

Step 6: Apply materials

Next, ask for basic materials: white siding, a black metal roof, timber and a lawn. Materials can come from free libraries such as Poly Haven, which the project can connect to.

Apply simple materials: warm white siding, black standing-seam metal roof,
timber porch posts, concrete path and lawn. Use shader nodes.

Step 7: Light and render

Finally, set up a sun for golden hour and a camera at eye level, then ask for a render. See our rendering tips for what makes an image look real.

Add low golden-hour sun and a soft sky, place a camera at eye level with
straight verticals, and render one 1920 x 1080 image.

Know the limits

This produces a visual model, not a buildable design. It doesn't include structure, code checks or construction details, so bring a real project to a licensed professional. Also, run only one MCP client at a time, and if your client can't find uvx, use its full path, as the README explains.
