Do I need a subscription to use the MCP server?

No. Without an account you see the description and place of each project, as on the website. An account allows saved searches; a subscription shows address, builder and the original source.

Which assistants support MCP?

Claude (claude.ai, desktop, Claude Code), ChatGPT, Cursor and most developer tools that can connect remote MCP servers with OAuth.

Does the assistant see more than I do on the website?

No. Every answer passes the same entitlement check as the website. Private builders stay masked, locked details stay locked.

Use Zuerst zuhause in Claude, ChatGPT and Cursor

The MCP server lets AI assistants query the building applications directly, set up in three steps.

What it is

Zuerst zuhause runs a server for the Model Context Protocol (MCP), the open standard AI assistants use to reach outside data. Once connected, your assistant can search the official building applications directly and, with an account, manage your saved searches. It sees exactly what you see on the website, nothing more.

Two addresses

https://zuerstzuhause.ch/mcp works without signing in and returns the description and place of each project, as a teaser for fresh publications. https://zuerstzuhause.ch/mcp/konto needs your account: on the first call the assistant opens the sign-in in your browser, you confirm the access, done. With a subscription it then gets address, builder, project author, zone and the original source, and can create saved searches.

Set-up

Claude (claude.ai or the desktop app): Settings → Connectors → “Custom connector” → enter https://zuerstzuhause.ch/mcp/konto. The sign-in dialog opens by itself.

ChatGPT: Settings → Connectors → add an MCP server, same address, authentication OAuth.

Cursor: Settings → MCP → “Add new global MCP server” and save {"mcpServers":{"zuerstzuhause":{"url":"https://zuerstzuhause.ch/mcp/konto"}}}.

Claude Code: claude mcp add --transport http zuerstzuhause https://zuerstzuhause.ch/mcp/konto, then /mcp to sign in.

What you can ask

“Which apartment buildings were filed in Winterthur in the last 30 days?” — “Show me new-build projects with at least ten apartments in the canton of Aargau.” — “Create a saved search for Uster within 5 km, residential only, four units or more.” — “Who is the builder of project X, and when does the objection period end?”

The tools behind this are search_projects, get_project, list_search_agents, create_search_agent and delete_search_agent. Your assistant picks them itself; you just ask.

Privacy and limits

Private builders stay masked as “Privatperson” over MCP too, as Swiss data protection law requires. Access is limited per address so a single assistant cannot overload the service. You can revoke a connected application at any time by removing the connector in your assistant. Companies get the same server with every publication type at https://neubau-radar.ch/mcp.
