On va où ? routes MCP server

by onvaou-app · official

Let your AI find places in Europe and plan bike, walking, scooter or wheelchair routes between them.

This is a small helper that lets your AI assistant look up places in Europe and work out routes between them. You can ask for a bike ride, a walk, a scooter trip or a wheelchair-friendly path, and it comes back with options and details. It is handy if you plan trips, commutes or outings and want the AI to do the looking up for you.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a little helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to the On va où ? routing service, which knows addresses and routes across Europe. Once it is connected, your AI can ask that service for places and paths, and then tell you the answer in plain words.

What this MCP server does

You ask your AI something like a safe bike route from one place to another. The AI first uses this helper to turn the place names into coordinates. Then it asks the helper for routes between those points, in the mode you want. The helper talks to the On va où ? service, which returns up to three route options with details like how much is on cycle lanes or unpaved. Your AI then shows you a short summary, and you can ask follow-up questions.

Flow diagram: you ask your AI “Safe bike route from Gare de Rennes to Thabor park”, the On va où ? routes MCP server connects it to On va où ?, and you get back up to three route options.

“What is the walking route from the Eiffel Tower to the Louvre?”
“Plan a wheelchair-friendly route from my hotel to the museum, avoiding steps”
“Show me a scooter route from Alexanderplatz to Tempelhofer Feld, avoiding unpaved roads”

What it gives back to you

You get a short readable summary in the chat first, then the same information in a structured form. For a place search, that means a list of matching places with their full names and a confidence score. For a route, you get up to three options with details like distance, climb, share of cycle lanes and turn-by-turn steps if you asked for them. Each answer also tells you how many searches or requests you have used.
