From the repository
- Free tier: 1,000 API calls per day
- Default limit: 2,000 API calls per day (can be adjusted in your account)
- Billing: Any calls beyond the free 1,000/day will be charged according to OpenWeatherMap pricing
- Usage cap: You can set a call limit in your account to prevent exceeding your budget (including capping your usage at the free tier limit so no costs can be incurred)
- If you reach your limit, you’ll receive a HTTP 429 error response
> Note: API key activation can take several minutes up to an hour. If you receive authentication errors shortly after subscribing or generating a new key, wait a bit and try again later.
python3 -m venv venv
source venv/bin/activate # Linux/Mac
pip3 install -r requirements.txt
This will install all the necessary dependencies to run the server and development tools.
export OPENWEATHER_API_KEY="your_api_key" # Linux/Mac
set OPENWEATHER_API_KEY=your_api_key # Windows
Add the following configuration to your MCP-supported client (e.g., Claude Desktop (instructions), Cursor):
{
"weather_forecast": {
"command": "python3",
"args": [
"/full_path/weather_mcp_server.py"
],
"env": {
"OPENWEATHER_API_KEY": "your_openweathermap_key_here"
},
"disabled": false,
"autoApprove": ["get_weather", "get_current_weather"]
}
}
If you’re using a virtual environment, your configuration should include the full path to the Python executable in the virtual environment:
{
"weather_forecast": {
"command": "/full_path/venv/bin/python3",
"args": [
"/full_path/weather_mcp_server.py"
],
"env": {
"OPENWEATHER_API_KEY": "your_openweathermap_key_here"
},
"disabled": false,
"autoApprove": ["get_weather", "get_current_weather"]
}
}
```
location
Location name as a string, e.g., “Beijing”, “New York”, “Tokyo”. The tool will handle geocoding this to a latitude/longitude coordinate.
api_key
OpenWeatherMap API key (optional, will read from environment variable if not provided)
timezone_offset
Timezone offset in hours, e.g., 8 for Beijing, -4 for New York. Default is 0 (UTC time). Times in the returned data will be accurate for this timezone.
Run directly without setting environment variables:
python weather_mcp_server.py
When calling the tool, you’ll need to provide the api_key parameter.
The server exposes two tools, get_weather and get_current_weather. Both tools accept the same parameters:
- location: Location name as a string, e.g., “Beijing”, “New York”, “Tokyo”. The tool will handle geocoding this to a latitude/longitude coordinate.
- api_key: OpenWeatherMap API key (optional, will read from environment variable if not provided)
- timezone_offset: Timezone offset in hours, e.g., 8 for Beijing, -4 for New York. Default is 0 (UTC time). Times in the returned data will be accurate for this timezone.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.
