What's in it

Data offered docs-verified: wind forecasts · wave forecasts · tides (HW/LW, observed, forecast, surge) · tidal currents · marina, harbour and anchorage POIs · scheduled bridge openings · Notices to Skippers · fairway depths and bridge air-draft clearance · locks · METAR/TAF aviation weather · sunrise, sunset, twilight and moon phase · live AIS vessel snapshot · global tide predictions (key required) · multi-source tidal/ocean currents (key required)
Coverage docs-verified: Dutch / North Sea waters (strong focus); some tools are global
Formats docs-verified: MCP streamable HTTP
Access docs-verified: Public-data tools need no key. Windy, WorldTides, Stormglass and AISStream need the user's own API key passed in the URL; all except Windy have a free tier. Server licence MIT (per ENTRY metadata, not DOCS).

Useful for

Use cases llm-inferred: Tide and surge levels at Dutch coastal sites for marine works or outfall boundary checks (tides_nl) · Wind and wave forecast windows for coastal survey or dredging campaign planning · Bridge clearance and fairway depth checks for barge or crane access routes (fairway_nl)
Audience llm-inferred: coastal and marine engineers · hydrologists · civils and BIM engineers planning marine logistics · GIS analysts

Limitations

Constraints llm-inferred: Built and documented for recreational sailing, not engineering or regulatory use · Official charts, almanacs and notices must be checked before relying on outputs · Windy, WorldTides, Stormglass and AISStream need user-supplied API keys; keyed tools only appear when the key is present · AISStream is community-fed and sparse mid-ocean · Some bridges may show '(name unknown)' where OSM has no nearby named bridge · All tool times are UTC · Depends on third-party public endpoints (RWS, NDW, OSM/Overpass, aviationweather.gov, Open-Meteo) with no stated SLA · No public hosted endpoint is documented; the user must run or host an instance (docs use a 'your-host' placeholder) · ENTRY metadata lists OAuth, but DOCS describe API-key URL parameters and state 'No OAuth required' for Claude.ai · Likely single-maintainer personal project ('Built by @ai_kulikov'), so maintenance risk
