Weather Forecast Tool

Description

This Python code provides a tool to fetch and summarize weather forecasts for a given location using the MET Norway API. It leverages the `FastMCP` framework for tool registration and uses `httpx` for asynchronous HTTP requests.

Features

• Weather Forecast: The `get_weather` function retrieves weather forecast data for a specified latitude and longitude.
• Daily Summary: The `summarize_daily_timeseries_most_occurrences` function processes the raw forecast data to provide a concise daily summary, including:

• HTTP Requests: The `make_net_request` function handles asynchronous HTTP requests to the MET Norway API.
• Weather Symbol Mapping: The `map_weather_symbol` function translates weather symbol codes from the API into human-readable descriptions.

Dependencies

• Python 3.13+
• `collections`
• `datetime`
• `typing`
• `asyncio`
• `json`
• `httpx`
• `mcp.server.fastmcp`

Setup

1. Install Dependencies:

# Install MCP and other dependencies as needed (see MCP documentation)

2.  **Obtain Coordinates:** You'll need the latitude and longitude for the location you want the weather forecast for.

## Usage

1.  **Import:** Import the necessary modules and initialize the FastMCP server.

from collections import Counter

from datetime import datetime, timezone, timedelta

from mcp.server.fastmcp import FastMCP

from typing import Any

import asyncio

import json

import httpx

mcp = FastMCP("weather")

2.  **Use the `get_weather` tool:**

async def main():

weather_data = await get_weather(55.6761, 12.5683) # Example: Copenhagen, Denmark

print(weather_data)

if __name__ == "__main__":

asyncio.run(main())

Replace `55.6761` and `12.5683` with the desired latitude and longitude.

## Tool Definition

\* `get_weather(latitude: float, longitude: float) -> str`
    * Retrieves and formats the weather forecast for a given location.
    * Arguments:
        * `latitude` (float): The latitude of the location.
        * `longitude` (float): The longitude of the location.
    * Returns:
        * `str`: A formatted string containing the daily weather forecast.

## MCP

The code uses the FastMCP framework. Please refer to the FastMCP documentation for details on how to set up and run the server.
