Projects
Create a project (create_project): a home3dplan MCP tool
create_project: A new, empty home design project owned by the signed-in person. Returns its id and a link that opens it in the editor.
`create_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 new, empty home design project owned by the signed-in person. Returns its id and a link that opens it in the editor.
A write. It saves one revision of the project, which appears in the open editor at once and can be undone there. Scope: **projects:write**.
Inputs
**name** (string, required): The project name
What comes back
What changed, in words and in a structured form, and the link that opens the project in the editor on the right storey and view.
Tip: if the project changed in the editor between two calls, the write is refused as a conflict and the assistant opens the project again. Nothing is overwritten.
Ask for it like this
"Start a new home3dplan project called Lakeside cabin."
The assistant chooses the tool and fills its inputs from what you said; you do not name the tool or type its inputs.
