Set layers (set_layers): a home3dplan MCP tool

What it does

The drawing’s layers, as the Layer manager has them: make a layer by name (with a discipline letter for the trades: A architecture, S structure, M mechanical, E electrical, P plumbing, D drainage, L landscape, I interiors), show or hide it, lock it, colour it (#rrggbb), and choose the active layer new entities go on. Existing layers are matched by name.

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

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

**layers** (({ name: string, discipline?: string, visible?: boolean, locked?: boolean, color?: string })[]): See the tool’s description.

**active** (string): the layer name new entities go on

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

"Use set_layers on my project."

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