Unofficial MCP server for the Windy Point Forecast API

What is the Windy MCP server?

Unofficial MCP server for the Windy Point Forecast API. The windy mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 3 defined tools rather than through you.

What it actually does

An MCP (Model Context Protocol) server that exposes weather, ocean wave, and air quality forecasts to AI assistants via the Windy Point Forecast API.

Its toolset

Everything the assistant can do here goes through one of these:

  • get_weather_forecast — The get_weather_forecast tool exposed by this server
  • get_wave_forecast — Fetch ocean wave data for any coastal or open-water coordinates
  • get_air_quality_forecast — The get_air_quality_forecast tool exposed by this server

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Configuration

You will need one environment variable: WINDY_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Windy's toolset — get_weather_forecast, get_wave_forecast, get_air_quality_forecast — is a fair guide to whether it matches your workflow.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the windy mcp server does with a few real requests.

  • Use Windy to get weather forecast.
  • Use Windy to get wave forecast.
  • Use Windy to get air quality forecast.

Frequently asked questions

It connects Windy to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (get_weather_forecast, get_wave_forecast, get_air_quality_forecast) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Windy directly.
