OhMyWind MCP server

OhMyWind ⛵

Talk to your LLM. Cast off with confidence.

OhMyWind turns any MCP-capable assistant (Claude, Le Chat, Cursor, Goose,

Zed, Continue) into a sailing planner. Ask in plain language, anywhere in

the world: get a per-leg ETA, a 1‑5 complexity score, and a deep-link to

the full plan. On the French Atlantic coast it goes further, swapping the

global current model for the SHOM Atlas C2D and MARC PREVIMER atlases.

Free, keyless, open source.

[!WARNING]

Decision-support tool, not a navigation instrument. OhMyWind does not

replace the official marine forecast from your national weather service,

up-to-date charts, or the skipper's judgement. Forecast models are sometimes

wrong: you remain responsible for your passage.

Try it in 30 seconds

1. Open your MCP client and add the endpoint:

https://mcp.ohmywind.fr/mcp

2. Ask, in your own words:

*"Demain matin, Marseille → Porquerolles, sur un Sun Odyssey 36. Bonne

idée ? Combien de temps et c'est tendu comment ?"*

3. Your assistant calls the OhMyWind tools and answers in plain language. On hosts that support the MCP Apps spec (Claude, Claude Desktop, ChatGPT, VS Code Copilot, Goose, Postman, MCPJam) you also get a live, interactive widget: the ohmywind.fr plan view rendered inline. On hosts that don't (Cursor, Le Chat, terminal), the assistant hands you the same plan as an ohmywind.fr deep-link. No account. No API key. No credit card.

First time with MCP? It takes 2 minutes. Pick your client on

modelcontextprotocol.io/clients,

then follow the

remote-server quickstart.

Claude Desktop users can start with the

user quickstart. In Le Chat,

add it under Connectors → Add connector → Custom MCP connector and paste

the endpoint above.

If your client only speaks stdio

Some hosts cannot reach a remote MCP server directly yet. Bridge it with mcp-remote, which runs locally and forwards to the endpoint:

{
  "mcpServers": {
    "ohmywind": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.ohmywind.fr/mcp"]
    }
  }
}

Nothing else to configure: no account, no API key, no OAuth, no credit card. A client that asks you for credentials is guessing rather than reading the server, and you can leave those fields empty.

Ask it something real

Three prompts, each exercising a different tool:

archetype. The assistant chooses from the descriptions; there is no server-side lookup table.

• "Quels bateaux tu connais ? J'ai un First 27." maps your boat to a polar

point, AROME first, in knots.

• "Le vent au cap Sicié samedi après-midi ?" returns wind and sea at one

every hourly departure up to 14 days out and compares them in one call.

• "Meilleur créneau cette semaine pour Marseille → Porquerolles ?" walks
