Also use it in ChatGPT or Claude
Simple House Planner is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
- 4
Use it in a chat
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT

Tools · 12
search_furnitureFinds furniture in the catalog by words such as bed, sofa or table, and by size such as w:1200. Use the item keys with plan.furniture and plan.against.list_projectsUse this when someone mentions one of their plans or asks what plans they have. Lists the plans in their account with titles, floors and last changes, newest first.create_projectUse this when someone asks to design, draw or plan a house, apartment, office, room or floor plan, and no plan of theirs fits. Starts a new empty plan to scale in their account and returns its ID. Build it with edit_project and show it with open_editor; do not describe a design irename_projectChanges the name of a plan in the person's account.delete_projectPermanently deletes one plan from the person's account. It cannot be restored. Call this only for a plan that the person named in words. When they name none, as in "delete my plans", do not call this: call list_projects, show the titles and ask which ones to delete.describe_planFacts that the planner computes for the site and for a floor or every floor: the site's location, time zone and north, rooms with areas and sizes, what each door connects, window directions, routes from the entrance, and warnings.query_projectRuns a read-only script for questions that describe_plan does not answer, and returns what it returns. Scripts work as in edit_project, but only plan.floors, plan.elements, plan.get, plan.describe, plan.warnings, plan.check and plan.search are available; plan.check("din18040-2") edit_projectChanges a plan with a short script of plan operations, which the person's open editors show at once. Returns the IDs that changed, the warnings and a description of every floor. A change is never final: undo_change takes it back and restores what it removed, for the last 50 changundo_changeTakes back your own last change to a plan. The person's own edits stay as they are.redo_changeMakes again your own last change to a plan. The person's own edits stay as they are.open_editorShows a plan in the Simple House Planner editor, where the person can change it by hand in 2D and 3D and sees your changes as you make them. Without a project ID it shows their plans to choose from.account_profileThe stable identifier of the linked Simple House Planner account.Recent checks
