Overview

Pascal Editor is an open-source 3D building editor that runs in your browser, with an MCP connector for AI agents. One command starts the editor and its connector on your computer; your agent can then create rooms, walls, doors, windows and roofs, place furniture, measure spaces and save the project, and you open the same project to look and keep editing. It suits architects, home builders and anyone sketching a room layout.

The agent builds a real 3D model in the editor, not just a picture of a floor plan, and you can keep editing it by hand.

Try these first

Start with the first one: it is a small task you can check easily.

Use the Pascal MCP server. Read pascal://agent-guide, create a small one-bedroom project, check it, save it and give me the editor link.First try · saves a project
My living room is [width] by [length] metres. Check whether a [size] sofa fits along the long wall and report the space left.saves a project
Add a door and two windows to the bedroom in [project name], then save it.
List the rooms in [project name] with their floor areas.

Capabilities

From the creator's documentation.

Toolset	What your agent can do	Access
Rooms and walls	Create rooms, walls, doors, windows, levels, stairs and roofs	Read + write
Furniture	Search the item catalog and place furniture on floors, walls or ceilings	Read + write
Measurements	Measure distances and check whether items collide or fit a footprint	Read
Check and save	Check the scene for problems, save it and return the editor link	Read + write
Scene questions	List projects, read rooms and summarise the current scene	Read

Good to know

You want an agent to sketch a room or a small home in 3D and check whether furniture fits. Pascal gives the agent building tools and measurements, saves the project locally and returns a link you open in the editor.

Limits

The local CLI supports macOS; the docs say Linux and Windows are not yet confirmed and point Linux servers to the Docker image.
A footprint check does not cover height, door swing or a delivery path. Give real room and item measurements and check the report against them.

How to start

Open your AI agentClaude Code, Codex, Cursor or another agent that supports MCP.
Paste the install requestIt asks your agent to read the official instructions, tell you what it will connect to and wait for your OK.
Give it a first taskAsk the agent to read the Pascal agent guide, create a small one-bedroom project, check it and return the editor link. Open the link and compare the rooms with what you asked for.

Steps follow the creator's instructions. The request tells your agent to read them first and wait for your OK.

Before you start
