Overview

AI-generated overview

Answers where boats stayed overnight worldwide, in what wind, with tonight's forecast, through four read-only lookup tools.

What you can do
  • Find anchorages near a position, with where boats stayed in tonight's forecast or a given wind
  • Get the evidence for one place: its nights, nights by compass wind direction and strength, boats by length and type, and daytime activity
  • Get ten-year wind climatology for a place, including strong-wind nights per month and commonest directions
  • Browse the directory of countries, regions and cruising areas with place counts
When to use it
Useful when planning or researching anchorages and want to know where boats actually stopped overnight and in what wind, or how windy a place is through the year. Also handy for browsing the site's directory of regions and cruising areas.
Requirements
A remote streamable HTTP endpoint; no packages, environment variables or headers are declared. No authentication is declared.
Before you install
The server states it is not for navigation and does not replace official nautical charts, so do not rely on it for safe passage planning. All four tools appear to be read-only lookups.

Installation

In SourceWeft

  1. Open Where Boats Anchor in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.whereboatsanchor%2Fanchorages/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

find_anchorages

Find anchorages near a position, tonight or in a wind

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. 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, and each place's fewest nights in any one of them. 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 what boats did at one place

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.

Parametersnamenearbay_id

get_climatology

Get the wind through the year at a place

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.

list_regions

List countries, regions and cruising areas

The site's directory of places where boats stayed the night. Without a country: each country with its number of places. With a country (directory slug or ISO code): its regions and cruising areas with their number of places. Each with the address of its directory page.
