List every provider air_choose can query, with its coverage region and whether it needs a live browser session (those are NOT included here — only providers that work with plain HTTP calls are).

Every provider uses its own internal airport/city/country codes — you cannot just pass a Russian or English place name straight into a search. Call this FIRST for both the origin and the destination before add_watch, so you can see what each provider actually understood the place as. Accepts a country name (RU or EN, e.g. "Таиланд" / "Thailand"), a 3-letter IATA code (e.g. "BKK"), or a handful of built-in city aliases (Moscow, London, Singapore, Delhi, ...). Returns, per provider, the list of matched airports/cities/country codes — an empty list for a provider means that provider does not serve that place at all (e.g. Ryanair has no Moscow routes), which is normal, not an error.

Add a route to monitor. originQuery/destinationQuery go through the same resolution as resolve_location for every requested provider, immediately, and the watch stores each provider’s resolved codes — you get that resolution back in the response so you can sanity-check it before relying on the watch. An immediate first check runs right away (you do not have to wait for the hourly cycle to get initial results) and its offers are returned too.

Stop monitoring a route and forget its price history.

List every currently watched route, with when it was last checked and how many offers it has.

Return the latest known offers for a watch, from the most recent check (hourly, or forced).

Return every offer discovered since the last time this was called — new routes/dates appearing, or a price drop below the previously-seen best price — across ALL watches, and clears the queue. This is the reliable way to find out "what changed": call it on your own schedule (e.g. once an hour) rather than relying on push notifications, since not every MCP host wakes an idle agent on server notifications.

Re-run the fare check for one watch right now, instead of waiting for the hourly cycle.
