Looking for a home in Switzerland with an AI assistant

What an MCP connector is

MCP, the Model Context Protocol, is an open standard that connects AI assistants to external services. A connector gives the assistant specific tools, which it calls when your question calls for them. At ImmGate: searching listings, reading a listing, finding a Swiss place, reading a guide.

ImmGate’s connector links to your free ImmGate account once you have allowed it. It publishes nothing. It only writes when you ask it to, to the advertiser of a property you are interested in, and you always receive a copy.

1. You You ask your question the way you would ask a person.
2. The assistant It calls ImmGate’s tools through the MCP connector.
3. ImmGate The same search as the website, with the same rules.
4. The listings They come back with their price, service charges and link.

With ChatGPT and other assistants

ChatGPT can use remote MCP servers, notably for its deep research. The menus depend on the plan, and OpenAI’s help describes them. ImmGate also answers the two tools that research expects, “search” and “fetch”.

Any other MCP-compatible assistant connects with the same address, over HTTP, and signs you in to your account with OAuth.

What you can ask it

• “A 3.5-room flat to rent around Geneva, up to 3000 francs a month.”
• “Houses for sale within ten kilometres of Zug, newest first.”
• “A studio a few kilometres from Fribourg.”
• “Explain the gross rent and the deposit of this listing.”
• “Does this listing, seen on another site, show the signs of a scam?”
• “Every morning, look for new 3.5-room flats around Lausanne and, if one suits me, write to the agency to arrange a viewing.”

The assistant passes your criteria to ImmGate’s search: the place and radius, the property type, rooms, budget, renting or buying. Unless you give a number, “around” counts 10 km, “in the … area” 20 km and “a few kilometres” 5 km. The ranking is the site’s: newest listings first, never according to payment.

Let your assistant search, and write, for you

With a scheduled task, meaning a search your assistant reruns every day, it keeps an eye on new listings and writes to the agency in your name as soon as one suits you. All you have to do is reply.

1. Every morning Your assistant reruns your search on ImmGate.
2. A listing matches It reads all of it: price, service charges, availability.
3. It writes to the agency In your name: your name, your e-mail address, your message.
4. The agency replies By e-mail. You already have the copy of the enquiry.

Your assistant only does this if you asked it to, with your real name and e-mail address. A listing receives at most one enquiry a week from you, and every copy tells you it was sent by your assistant.

Your account: your file and your favourites

Connected to your account, your assistant can also fill in your application file, upload your documents and manage your favourites. It can attach your complete file when it writes to an agency for you.

1. You add it A single address: immgate.ch/mcp.
2. You allow it You sign in on immgate.ch and accept.
3. It fills in your file With what you give it, nothing else.
4. It attaches it to your requests Only if you ask it to.

The assistant never sees your password, nor the content of your documents, which stay encrypted. The agency only opens your file with a code sent to its address, and you see who opened it. You disconnect the assistant whenever you like, on the “My connected assistants” page.

The right reflexes

• Open the listing on immgate.ch before deciding: an assistant can summarise wrongly, and the listing is what counts.
• Compare gross rents, service charges included, rather than net rents.
• Pay nothing before you have visited, and only place a deposit in a bank account in your name.
• To write to the advertiser, the assistant goes through ImmGate: the enquiry goes out with your name and e-mail address, you receive a copy, and it never gets the broker’s address.

For agencies and property management firms

There is nothing to do: your listings published on ImmGate are found by assistants, in their languages, with the same visibility as everyone else’s. Your fees appear as you publish them, and enquiries reach you through the listing’s form, as usual.

And the enquiries that assistants send about your listings reach you like those from the website, by e-mail, marked as sent by an assistant.

Before the portal opens

Until ImmGate opens in 2027, the listings an assistant finds are demonstration listings: made-up agencies, photos that do not show the properties. Every answer says so, and the assistant is instructed to tell you. No enquiry is sent to agencies until then.
