## Tools (as reported by the server, not verified)

- `find\_vessels\_in\_area`: Vessels currently inside a latitude/longitude bounding box, newest report first, with optional kind and ship-type filters. Use for what is in a port, a strait, or a stretch of coast. Anonymous calls may cover 100 square degrees per call.
- `find\_vessels\_near`: Vessels within a radius \(default 10 NM, maximum 50\) of a point or of another vessel's last known position, nearest first, each with distance and bearing from the centre. Use for what is near this position or what is around vessel X.
- `get\_coverage`: Where Open Waters AIS is hearing AIS right now: sources with their current delay, stations, freshness, and vessel counts. Pass a bounding box to learn which stations cover it and how many vessels are in it, or a station id for that station's numbers. Vessel counts cover the last 30 minutes; max\_age
- `get\_vessel\_track`: The positions heard from one vessel over a time range, oldest first, with speed, course, and navigational status. Positions implying an impossible speed for the vessel are left out. Use for where a ship was yesterday, when it left port, or its route today. Give the vessel's mmsi, or its imo with a f
- `get\_vessels`: Last known position and particulars of specific vessels by MMSI \(Maritime Mobile Service Identity\), or by IMO number with a feeder or partner token: the last report heard for each, however long ago, with destination, ETA, draught, and dimensions once its static data has been heard, and which identif
- `search\_vessels\_by\_name`: Vessels whose name contains the text, case-insensitive, among every vessel the network has heard, each with its last known position. Use to turn a name into an MMSI, then get\_vessels or find\_vessels\_near for detail. An optional bounding box narrows the search. With a feeder or partner token, text of
