Cardea Weather MCP Server

The Cardea Weather MCP Server provides weather data from OpenWeatherMap.org to MCP clients. It supports two transport types: stream-http and sse.

Tools

  • get_current_weather
    • Get the weather for a given city
    • Input parameters:
      • location: The city to get the weather for, e.g., "Beijing", "New York", "Tokyo".
      • unit: The unit to use for the temperature, e.g., "celsius", "fahrenheit". Default is "celsius".
    • Returns the current weather information for the given city, including temperature, humidity, weather condition, etc.

Build

# build mcp server
cargo build --release

Run

[!IMPORTANT]

The mcp server will use the OPENWEATHERMAP_API_KEY environment variable to get the weather data from OpenWeatherMap.org. If you don't have an API key, you SHOULD apply one from OpenWeatherMap.org and set it by running the following command:

export OPENWEATHERMAP_API_KEY=<your-api-key>

Now, let's start the mcp server. You can choose to start the server with different transport types by specifying the --transport CLI option. The default transport type is stream-http. In addition, you can also specify the socket address to bind to by specifying the --socket-addr CLI option. The default socket address is 127.0.0.1:8002.

# run mcp server (stream-http)
./target/release/cardea-weather --transport stream-http

# run mcp server (sse)
./target/release/cardea-weather --transport sse

If start successfully, you will see the following output:

Cardea Weather MCP Server is listening on 127.0.0.1:8002
