3D New Era AI MCP server

3D New Era AI

English · Português (Brasil) · Website

An open-source home design, floor plan and interior design editor written in Rust — a Sweet Home 3D alternative for Windows, macOS and Linux — that is AI-native from day one: the editor ships with a built-in Model Context Protocol server, so an AI agent draws walls, furnishes rooms, builds joinery, checks lighting and ergonomics against standards and renders the photos alongside you, with every change showing up live on screen and one Ctrl+Z away. Everything runs on your own machine: no account, no subscription, no cloud. The interface speaks Portuguese, English, Spanish and French.

Download

Windows — open PowerShell and paste:

irm https://raw.githubusercontent.com/leandrodaf/3d-new-era-ai/main/scripts/install-windows.ps1 | iex

macOS (Apple Silicon and Intel) — open Terminal and paste:

curl -fsSL https://raw.githubusercontent.com/leandrodaf/3d-new-era-ai/main/scripts/install-macos.sh | bash

That's it: the app shows up in the Start menu / Launchpad, no administrator password, and the same command updates it. Prefer a plain download?

First launch of a plain download

The builds aren't signed with a paid Apple or Microsoft certificate, so the system asks once:

More info → Run anyway.

• Windows: unzip, open newera-gui.exe; if SmartScreen appears, click

Open. On macOS 15 and later, open it once, then go to System Settings → Privacy & Security → Open Anyway. Or run xattr -dr com.apple.quarantine "/Applications/3D New Era AI.app".

• macOS: unzip and move 3D New Era AI to Applications. Right-click it → Open →

./newera/install-desktop.sh to add it to the menu with its icon and to give .newera files their own icon and double click (--uninstall undoes it).

• Linux: tar xzf newera-linux-x64.tar.gz && ./newera/newera. Run

The one-line installers above skip these prompts.

Next: connect your AI — Claude, Codex, Gemini, Cursor, VS Code, DeepSeek and others.

Showcase

A real 105 m² apartment, traced from an openly licensed floor plan and furnished, lit and photographed by an AI agent through MCP alone — walls from the scan, doors that swing the right way, slatted TV wall, L kitchen and wardrobe from cabinetrun, downlights sized by photometry against NBR ISO/CIE 8995-1, path-traced photos. Every image below came out of the editor itself. See how it was built →**

Shortened. The full README is on GitHub.
