Tools as reported by the server

• search_vessels
  Find ships by name (or part of it), MMSI (9 digits) or IMO number (7 digits). Returns live ships first, then ships out of range with their last known position (up to 7 days). List results are compact rows (mmsi, name, category, flag (ISO code from the MMSI), lat, lon, speed_kn, course_deg, length_m,
• get_vessel
  Everything known about one ship now: identity (name, IMO, call sign, flag, type, size), last position, speed, course, heading, navigational status, destination (port codes decoded) and ETA as given by the crew, how long ago it was heard, its track over the last 40 minutes, and the data sources to cr
• vessels_in_area
  Ships heard in the last hour inside a box (at most 5° on each side), largest first. List results are compact rows (mmsi, name, category, flag (ISO code from the MMSI), lat, lon, speed_kn, course_deg, length_m, destination, age_s, status, source); call get_vessel for full details of one ship. Private
• vessels_near
  Ships heard in the last hour within a radius (at most 50 nautical miles) of a point or of another ship, nearest first. List results are compact rows (mmsi, name, category, flag (ISO code from the MMSI), lat, lon, speed_kn, course_deg, length_m, destination, age_s, status, source); call get_vessel fo
• vessel_track
  Where a ship has been between two times (UTC, ISO 8601), from the AIS Trail archive. Needs an AIS Trail API key sent by the MCP client as the HTTP header 'Authorization: Bearer ap_live_…' (keys at https://aistrail.com); clients that cannot add headers (OAuth-only web connectors) cannot use it yet. R
• data_status
  How many ships are live now (live_ships_private: how many of them are private vessels, counted only), how many are known from the last 7 days, the date range of the history archive per source with available_until (the latest time vessel_track can return for that source on plans without live data), a
• find_port
  Find ports by name (or part of it), UN/LOCODE (e.g. NLRTM) or two-letter country code (e.g. NL) in the port reference (World Port Index and UN/LOCODE ports): id (for port_calls), name, country, UN/LOCODE, position, harbor size (World Port Index ports only) and the radius of the port area used to det
• vessel_port_calls
  Port calls of a ship between two times (UTC, ISO 8601), from the AIS Trail archive: port, arrival, departure, draught on arrival and departure, cargo estimate (loaded, ballast or unchanged, from the draught change), previous and next port. Give mmsi or imo. A port call starts when the ship stops for
• port_calls
  Ships that called at one port between two times (UTC, ISO 8601), from the AIS Trail archive: ship (with its flag from the MMSI), arrival, departure, draught on arrival and departure, cargo estimate, previous and next port. Get the port_id from find_port. event: any (in port at any time in the range,

  Events of a ship between two times (UTC, ISO 8601), computed from the AIS Trail archive. from and to are optional: without to, now (24 hours ago on plans without live data); without from, 7 days before to (on Free, no earlier than the oldest day the plan includes), as on the REST endpoint.

• lookup_vessels
  Records of up to 20 ships at once from the AIS Trail archive, by mmsi and/or imo (lists): identity and particulars (name, IMO, call sign, type, flag from the MMSI, length, beam, estimated deadweight, first and last seen) and sanctions flags by IMO number from three official lists: OFAC SDN, UK Sanct
