OhMyWind — Claude Code MCP server: what it does, how to install
Builds sailing passage plans using wind and tidal forecasts inside your AI assistant. Helpful for skippers scouting departure windows and route difficulty.
claude mcp add --transport http sailing-planner https://mcp.ohmywind.fr/mcpWhat OhMyWind does
OhMyWind connects your assistant to marine weather data without requiring tokens. It gathers forecasts through Open-Meteo using GFS and ECMWF models. Near French shores, it switches to high-resolution AROME data and SHOM tidal atlases.
The server helps inspect tidal streams and compute multi-leg routes. It maps your vessel against eight polar archetypes. It can also evaluate hourly departure windows across a 14-day range, scoring each slot from 1 to 5 in complexity.
Keep in mind that OhMyWind offers advisory guidance, not certified navigational charting. Clients lacking native HTTP support require an mcp-remote proxy to forward traffic.
What it helps with
- calculate passage durations across route legs
- identify the calmest departure window over 14 days
- score route complexity on a 1 to 5 scale
- check tidal stream timings and slack water in coastal channels
Example prompts for the agent
- Plan a passage from Marseille to Porquerolles tomorrow on a Sun Odyssey 36 and estimate the duration.
- Check the marine wind and sea state near Cap Sicié for Saturday afternoon.
- Find the best weather window this week to sail from Brest to Saint-Malo.
