A zero-config MCP weather server for current conditions and daily forecasts via Open-Meteo, with no weather API key required.
Get current weather for a location worldwide: temperature, apparent temperature, condition, humidity, wind speed, and pressure.
Get a daily forecast for 1–7 days, including highs, lows, conditions, and precipitation probabilities.
Choose Celsius or Fahrenheit; Celsius is the default.
Resolve locations automatically through Open-Meteo geocoding.
Use it from MCP clients such as Claude Desktop over stdio.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Weather API MCP What's the weather in New York?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A zero-configuration Model Context Protocol (MCP) weather server for Claude and other MCP clients. It provides current conditions and forecasts using the free Open-Meteo APIs—no weather API key required.

Try the SkyWear preview in Claude.
For local development, open SkyWear on localhost after starting your local preview server. This address only works on the computer running the server; it is not a public website link.
SkyWear is a responsive, animated weather-and-outfit interface. It presents current conditions, hourly and 7-day forecasts, sunrise and sunset, wind, humidity, UV and air-quality details, location favorites, temperature-unit switching, sharing, and English, German, French, Spanish, and Kiswahili language options.
The supplied preview is currently configured with DEMO=true. It shows sample data for Ingolstadt, hides the city-search form, and does not make live weather requests. The HTML contains a live-data path using Open-Meteo geocoding, forecast, and air-quality APIs; set DEMO=false to use that path. Browser geolocation requires a secure context (HTTPS or localhost).
The browser preview is a separate frontend concept; it is not the MCP server itself. The MCP server continues to run over stdio for MCP clients.

uv sync
uv run weather-mcpThe server uses stdio transport for MCP clients. To install it into the active Python environment instead, run pip install -e . and then weather-mcp.
After installing the project with uv sync, add the following to your Claude Desktop MCP configuration, replacing /absolute/path/to/WEATHER_API_MCP with this repository's directory:
{
"mcpServers": {
"weather": {
"command": "uv",
"args": [
"--directory",
"/absolute/path/to/WEATHER_API_MCP",
"run",
"weather-mcp"
]
}
}
}get_weatherParameters: location (string), unit (celsius or fahrenheit, optional; defaults to Celsius).
Returns the resolved location, temperature, apparent temperature, weather condition, humidity, wind speed, and pressure.
get_forecastParameters: location (string), days (integer from 1 to 7, optional; defaults to 5), and unit (celsius or fahrenheit, optional; defaults to 5).
Returns daily high and low temperatures, conditions, and precipitation probabilities.
Location lookup and weather data are provided by Open-Meteo. Internet access is required for live weather; no account or API key is needed.
Get a daily weather forecast for 1–7 days for a location.
Inputs: location (required), days, unit. Returns: object
Get current weather for a place. Wind speed is returned in km/h.
Inputs: location (required), unit. Returns: object

Scored across 2 tools
get_weather and get_forecast have clearly distinct purposes: current conditions versus daily forecast. An agent can easily choose the correct tool based on whether it needs present weather or a multi-day outlook.
Both tools follow a consistent get_<noun> pattern. The naming is predictable and directly reflects the returned data.
Two tools are thin for a weather API surface, though they cover the most common current-weather and forecast use cases. Additional tools for hourly forecasts, alerts, or location lookup would make the set feel more complete.
The core weather workflow—current conditions and 1–7 day forecasts—is covered without dead ends. Minor gaps remain around hourly forecasts, severe weather alerts, and location resolution/geocoding.
