Worldwide tide times and heights, marine weather, sea temperature, sun and moon for 13,000+ ports.
Remote TidesAtlas server giving an assistant worldwide tide predictions, marine and weather forecasts, and sun/moon data for 13,000+ ports.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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.tidesatlas%2Ftides/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.Add this to your client's mcpServers config.

Get tide predictions (high/low water times and heights) for a port or coordinates. Returns extremes with datetime, height in meters, and type (high/low). Supports 13,000+ stations in 180 countries.
latlondatedaysportdatumSearch for tide stations by name or country. Returns port name, slug, coordinates, timezone, country.
limitsearchcountryList all 188 countries that have tide stations, with their station counts and ISO codes.
Takes no parameters.
Get weather forecast (temperature, wind, precipitation, UV, conditions) for a port or coordinates. Returns hourly and daily data.
latlondaysportGet ocean and wave forecast (wave height, swell, sea state on Douglas scale). Returns hourly and daily data.
latlondaysportGet sun and moon data: sunrise, sunset, dawn, dusk, day length, moon phase, illumination, moonrise, moonset.
latlondatedaysportGet unified weather + marine + astronomy data in one call. More efficient than calling each separately.
latlondaysportincludeGet historical tide predictions and weather data for past dates. Tides up to 365 days, weather up to 90 days.
daterequireddaysportrequiredincludeGet real-time sea level observations from REFMAR/SHOM tide gauges (French stations only). Returns 10-minute interval readings.
datedaysportrequiredGet rain radar tile URLs for a location. Returns past frames and short-term nowcast frames for map overlays.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
