A lightweight Model Context Protocol (MCP) server that enables AI assistants like Claude to retrieve and interpret real-time weather data.
Installing on Claude Desktop
To use your MCP server with Claude Desktop, add it to your Claude configuration:
1. Local mode
{
"mcpServers": {
"weather-mcp-server": {
"command": "/path/to/weather-mcp-server",
"env": {
"WEATHER_API_KEY": "your-api-key"
}
}
}
}
You can get an API key from your personal account on WeatherAPI.
2. Remote mode
{
"mcpServers": {
"weather-mcp-server": {
"url": "http://host:port/sse"
}
}
}
Build from source
You can use go to build the binary in the cmd/github-mcp-server directory.
go build -o weather-mcp-server ./cmd/weather-mcp-server
Using MCP with Docker Containers
1. Build the Docker Image:
docker build -t weather-mcp-server .
2. Run the Docker Container:
docker run -e WEATHER_API_KEY=your-api-key -d --name weather-mcp-server -p 8000:8000 weather-mcp-server
Replace your-api-key with your actual WeatherAPI API key.
