Swiss Open Data MCP server

Ask your AI about Swiss trains, weather, rivers, companies, parliament and more, with no setup or keys.

This is a helper that connects your AI assistant to lots of official Swiss open data. You can ask about trains, weather, river levels, companies, holidays, parliament and many other things, and get real answers instead of guesses. It is handy for anyone living in or curious about Switzerland, and you do not need any technical skills or accounts.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to a service. This one connects your AI to Swiss open data sources like SBB trains, MeteoSwiss weather and the ZEFIX company registry. Once it is connected, you just ask in normal words and the AI uses this helper to look things up for you.

What this MCP server does

You ask your AI a question in plain language, like when the next train leaves or how warm the Aare is. The AI passes your request to this helper program. The helper then talks to the right Swiss data source, such as the train timetable, the weather service or the company registry. It brings the answer back to your AI, which explains it to you in the chat. You do not have to visit any website or fill in any forms yourself.

Flow diagram: you ask your AI “Next 5 trains from Zürich HB to Geneva”, the Swiss Open Data MCP server reaches Train timetable, Weather service, River temperatures, Company registry, Parliament records and Post and postcodes, and you get back clear answer in chat.

What it gives back to you

You get clear answers in the chat, often with lists, numbers or short summaries. For example, you might see a list of train times, a temperature reading, or a company's details. Sometimes it gives you a link to a map or a PDF. It does not change anything on those websites; it only reads and reports.

Before you start

What you need

An AI app that supports MCP servers, like Claude Desktop or Cursor
Node.js installed on your computer (the free program that runs npx commands)

Good to know

It only reads public data, so it will not change or delete anything, but always double-check important details like train times or legal information.

Install it with your AI
