Global Weather MCP Server

A Model Context Protocol (MCP) server that gives AI assistants access to weather data without API keys.

• US weather alerts from the National Weather Service API

• US point forecasts from the National Weather Service

• Global 5-day forecasts from Open-Meteo, including India

Requirements

Check your local versions:

python --version
uv --version

Related MCP server: Weather MCP

Installation

git clone https://github.com/YOUR-USERNAME/global-weather-mcp-server.git
cd global-weather-mcp-server
uv sync

No API keys are required.

Connect to Claude Desktop on Windows

For the Microsoft Store/package install of Claude Desktop, open this config file:

%LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json

Add only this server entry inside the mcpServers object:

{
  "mcpServers": {
    "global-weather": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\path\\to\\weather-mcp",
        "run",
        "global_weather_mcp_server.py"
      ]
    }
  }
}

If the config file already has other MCP servers, keep them and add only the global-weather block. Restart Claude Desktop after saving the file. The server should expose these tools:

• get_alerts

• get_forecast

• get_forecast_global

Tools

get_alerts

Get active weather alerts for a US state.

Example:

What are the active weather alerts in California?

get_forecast

Get a detailed National Weather Service forecast for a US location by latitude and longitude.

Example:

What's the weather forecast for latitude 40.71, longitude -74.01?

get_forecast_global

Get current conditions and a 5-day forecast for any location worldwide by latitude and longitude.

Examples:

What's the weather forecast for latitude 19.0760, longitude 72.8777?
Get the weather for latitude 28.6139, longitude 77.2090.

Test Locally

Run the MCP server directly:

uv run global_weather_mcp_server.py

If it starts and waits silently, the server is ready for an MCP client.
