Open Waters AIS is a remote MCP server that gives an AI agent 6 tools, among them find_vessels_in_area, find_vessels_near, get_coverage. It answers at https://ais.openwaters.io/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 6 November 2026, succeeded.
Live AIS vessel positions by MMSI, name, area, or radius, plus coverage. No sign-in, no key.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
find_vessels_in_area | Vessels currently inside a latitude/longitude bounding box, newest report first, with optional kind and ship-type filters. Anonymous calls may cover 100 square degrees per call. Inputs: bbox, kind, flag, types, limit |
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. Inputs: lat, lon, mmsi, radius_nm, kind, flag |
get_coverage | Where Open Waters AIS is hearing AIS right now: sources with their current delay, stations, freshness, and vessel counts. A bounding box adds the stations whose coverage overlaps that area and a count of vessels in it. A station ID adds sta Inputs: bbox, station, 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. A vessel can be identified by MMSI, or by IMO with a feede Inputs: mmsi, imo, from, to, interval_minutes, limit |
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 dimen Inputs: mmsi, imo |
search_vessels_by_name | Vessels whose name contains the text, case-insensitive, among every vessel the network has heard, each with its MMSI and last known position when available. An optional bounding box narrows the search. With a feeder or partner token, text o Inputs: name, bbox, flag, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://ais.openwaters.io/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
