A production-ready MCP server that provides real-time weather information, forecasts, air quality, and weather alerts through the OpenWeatherMap API. It integrates with Claude Desktop and other MCP-compatible clients for natural language weather queries.

Provides authoritative astronomical data including moon phases, solar eclipses, and sun/moon rise and set times using the US Navy API or offline Skyfield calculations. It enables users to query Earth's seasons and celestial events for any location and date.

Enables scheduling of construction works against weather forecasts, using deterministic tools to check weather suitability, estimate curing times, and place dependent tasks into the earliest non-prohibited time windows.

An MCP server that uses Playwright to scrape Israeli weather forecasts from weather2day.co.il by automating a real browser, enabling an LLM to answer questions about current conditions and hourly forecasts for Israeli cities.

An MCP server that provides weather forecasts and current conditions for any city via the free Open-Meteo API, with no API key or account required.

An MCP server that uses Playwright to browse Israeli weather forecasts from weather2day.co.il, allowing LLMs to control a browser to fetch real-time weather data.

Solar vitamin D: whether the sun where you are can make vitamin D right now, how many minutes your Fitzpatrick skin type needs for a target dose, which months of the year synthesis is possible at your latitude, and how much a sun session produced. Computed from solar geometry, a clear-sky UV model with ozone and altitude, and live Open-Meteo UV data.

Provides Open-Meteo weather tools that return both structured forecast data for the model and a weather card (image link or text) for the user, plus geocoding of place names to coordinates. Requires no API key and works over stdio or streamable HTTP.

MCP server providing Korean weather forecasts from the KMA (short-term, hourly, daily) and timezone utilities (current time, conversion, lookup) using only standard Python zoneinfo.

Official aviation data MCP by Flight Master DAST (航班管家 DAST), providing flight status, route search, onboard comfort, delay and cancellation risk, airport weather forecasts, and real-time or historical flight trajectories.

Combines UK Met Office weather forecasts with travel routing to provide outfit recommendations for walking, cycling, or driving journeys.

Gives MCP clients access to 35 years of bias-corrected daily weather records for five Gilgit-Baltistan stations, with tools for daily values, long-term trends, cross-station comparison and rainfall thresholds. It also produces a live 1-16 day flash-flood screening outlook scored against each valley's own history, while flagging data break caveats that could mislead trend analysis.

Provides access to German Weather Service (DWD) data via the Bright Sky API, including current conditions, forecasts, and official weather alerts. Users can retrieve weather information and locate stations using either city names or geographic coordinates.

Provides access to real-time and historical water conditions of the Aare river in Switzerland, including water temperature, flow rates, swimming recommendations, and data from multiple monitoring locations along the river.

Enables AI assistants to retrieve point forecasts, active weather warnings, and live station observations for Sweden and the wider Nordic area through public open-data APIs, with no API key or account required.
