Where Boats Anchor MCP
This MCP server allows AI assistants to query historical AIS data and weather forecasts to determine where boats stayed at anchor, the wind conditions during those nights, and climatology for specific locations. It provides tools to find anchorages, get detailed bay evidence, retrieve wind climatology, and list regions, supporting boating research and planning.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

find_anchorages — Find anchorages near a position, tonight or in a wind
Advertised read-only
Lists the places near a position where boats stopped, overnight or by day, with where boats stayed in tonight's forecast there or in a given wind. For tonight, call it without wind_from and wind_kn: the answer then carries tonight's forecast at the position and each place's nights in each of tonight's winds, as the site's Tonight does. Give a wind only to ask about that wind. Each place comes with how far and which way it lies from the position (e.g. 0.5 NM SW), its nights, where it is, its page and its place on the map. With a wind, each place gets its nights in that wind, split by strength, with the gusts on those nights (kt), and the list is sorted by those nights. A wind is counted as the site counts it: its compass point at 10 or 20 kt or more, as the forecast's band (e.g. wind_kn 15 counts E 10 kt or more). wind_from alone counts the direction at any strength. Under 3 kt (wind_kn in whole knots) the wind has no settled direction, so every night counts. A night counts once, in the wind it blew from most. Tonight is counted as the site's Tonight counts it: tonight's forecast times that are night there, each counted in its compass point at 10 or 20 kt or more, as its band (every night under 3 kt), and each place's fewest nights in any one of them. Where a place faces open water and tonight's swell there is 0.5 m or more, a time's nights are those that also had that swell, as on the site. Places with a night in every one of tonight's winds come first, by those fewest nights, then the rest. Without a forecast, by distance. Positions are WGS84 decimal degrees.

}get_bay_evidence — Get what boats did at one place
Advertised read-only
What boats did at one place, as its page on the site shows it. Its nights. Its nights by the eight compass points the wind blew from, split under 10, 10 to 20 and 20 kt or more, with the different boats and the windiest night of each. Its boats by length and type (cells under 3 boats null), its day stops by wind, its nights by swell direction where its page shows them, and the places nearby with how far and which way. It carries tonight's forecast at the place: the night's strongest forecast wind and the place's nights in that wind, as its page's Tonight shows it. Give bay_id, or name with near (WGS84 decimal degrees) to rank places of one name. Several places of one name come back as candidates.

}get_climatology — Get the wind through the year at a place
Advertised read-only
Wind through the year at a place, as its page shows it: for each month, the nights whose strongest hour reached 20 kt and 30 kt, each year's fewest and most of them, the commonest directions of the nights of 20 kt or more, and the strongest gust, over ten years, for the area round the place. The first call for an area can answer preparing, then ready a few minutes later.
