**Free. No account, no API key, no sign-up.** One line and your assistant knows
whether the A8 is jammed, whether your train is late, where the nearest
Type 2 charger is (and whether it is free, where the operator publishes that)
and whether the lift at your station works — from official
German open data, live, with the source named in every answer.

> **Beta.** ViaFrei is being stabilised: sources are still being added, and
> answers and coverage can change. The answers are written by an AI assistant
> from our data, and AI can make mistakes, so check anything important (a
> closure, a departure, a price) against the source each answer names.

> **New in 1.8:** a twenty-first tool, **`find_sharing`**, for shared bikes
> (nextbike and Donkey Republic). **Berlin and Brandenburg** punctuality now
> comes from VBB's own realtime feed. Road answers now include police and city
> traffic reports from Baden-Württemberg, Schleswig-Holstein and Berlin (and
> from Köln and Hannover whenever those cities publish one), and roadworks on
> Bundes- and Landesstraßen in Niedersachsen, Sachsen and Thüringen. **Charging** gains the Bundesnetzagentur register and
> more live status, and **parking** gains Hamburg, Münster and NRW car parks.
> Every source is listed in [SOURCES.md](SOURCES.md).

## 🧳 What you can ask

You don't need to know any tool names. Ask the way you'd ask a friend who
happens to have every German traffic feed open. German or English; the answer
comes back in the language you asked in.

| when you're… | ask |
|---|---|
| 🌅 **about to commute** | *Fahren Busse und Bahnen in Bayern gerade pünktlich?* · *When does the next train leave Hamburg Hbf?* |
| 🚗 **about to drive** | *Gibt es Stau auf der A8?* · *Are there roadworks on the A7 next week?* · *Is the A1 closed anywhere?* |
| 🚧 **stuck in traffic** | *How much time is the jam on the A3 between Frankfurt and Würzburg costing right now?* · *Is traffic backed up on the Cologne motorway ring — A1, A3 or A4?* · *Ist der Elbtunnel auf der A7 heute Nacht gesperrt?* |
| ⚡ **driving electric** | *Where can I charge with Type 2 near Leipzig?* · *Wo gibt es einen Schnelllader mit 150 kW bei Nürnberg?* |
| 🅿️ **driving a lorry** | *Find a rest area with lorry parking on the A9* · *Wo ist der nächste Lkw-Parkplatz an der A7?* |
| ♿ **travelling step-free** | *Funktioniert der Aufzug am Bahnhof Köln Messe/Deutz?* |
| 🌦️ **watching the weather** | *Gibt es eine Unwetterwarnung für Freiburg?* |
| 📍 **looking for a place** | *What is the address of the Elbphilharmonie in Hamburg?* · *Welche Apotheken gibt es in Fulda?* · *My satnav shows 50.1109, 8.6821 — what address is that?* |
| 🇩🇪 **new to German roads** | *Do I need an emission sticker for Stuttgart?* · *Is there a speed limit on the Autobahn?* |
| ⏳ **waiting for news** | *Tell me as soon as the closure on the A7 is lifted.* · *Sag mir Bescheid, wenn in Köln ein Viertel oder mehr der Bus- und Bahnfahrten verspätet ist.* · *Warn me when a DWD severe-weather warning comes into force for Cologne.* |

**What the answers cover, honestly.** Live traffic is the motorways. Closures
and roadworks also cover federal roads, Land roads in Niedersachsen, Sachsen and
Thüringen, and the traffic reports some Länder and cities publish (Baden-Württemberg,
Schleswig-Holstein, Berlin, Köln, Hannover); other city streets are not covered.
Places and addresses come from OpenStreetMap, so what is not mapped there cannot
be found, and opening hours and ratings are not part of it. A **watch** lives in
the conversation that opened it: the server keeps every change there, and your
assistant shows it when you ask, or on its own if your client supports MCP
notifications. Nothing is sent by e-mail or SMS. Up to 10 watches per
conversation, each for up to 24 hours (3 by default), and a road is watched as a
whole, not one section of it.

## 💬 Real answers

These came back from the production server at `https://mcp.viafrei.de/mcp`
(server 1.8.18) on **2026-10-06, 23:00 Berlin time**. They are not mock-ups. Each
one shows the first lines of what the tool returned, and the source line exactly
as it was sent, shortened where marked.

The railway station and the Stadtbahn stop below it, from two operators, in one
answer. For anyone with a wheelchair, a pram or a heavy suitcase, this is the
difference between a station being usable and not.
*Edited: most facilities of both lists omitted, and the source lines cut.*

Region-wide, with the method stated, and the operators' own service alerts
beside the figure. The share-alike condition arrives as part of the answer,
because it is part of the data.
