Open a project (open_project): a home3dplan MCP tool

open_project: A summary of a project: its storeys with their rooms and areas, walls, openings, roofs, site and placed objects, plus its thumbnail when it has one. Call this before building on a project.

`open_project` is one of the 24 tools the home3dplan MCP server offers an assistant. Connect [Claude](/mcp/claude), [Claude Code](/mcp/claude-code) or [ChatGPT](/mcp/chatgpt) and it is available in the conversation.

What it does

A summary of a project: its storeys with their rooms and areas, walls, openings, roofs, site and placed objects, plus its thumbnail when it has one. Call this before building on a project.

A read. It changes nothing in the project. Scope: **projects:read**.

Inputs

**projectId** (string, required): See the tool’s description.

What comes back

A summary in words and in a structured form: the storeys with their rooms and areas, walls, openings, roofs, the site and the placed objects, and the project’s thumbnail when it has one.

Ask for it like this

"Open my project Stone house and tell me what is in it."

The assistant chooses the tool and fills its inputs from what you said; you do not name the tool or type its inputs.
