Hong Kong Observatory MCP Server

A Model Context Protocol (MCP) server that provides weather information of Hong Kong Observatory.

Features

• Weather information (forecasts, warnings, current conditions)
• Earthquake information
• Gregorian to Lunar calendar conversion
• Rainfall data from monitoring stations

Data Source

This project utilizes the official HKO Open Data API:

• Weather Information base URL: https://data.weather.gov.hk/weatherAPI/opendata/weather.php
• Earthquake Information base URL: https://data.weather.gov.hk/weatherAPI/opendata/earthquake.php
• Gregorian-Lunar Calendar Conversion base URL: https://data.weather.gov.hk/weatherAPI/opendata/lunardate.php
• Rainfall in the Past Hour from Automatic Weather Station base URL: https://data.weather.gov.hk/weatherAPI/opendata/hourlyRainfall.php
• HKO Open Data API Documentation

Prerequisites

• Python 3.10 or higher

Installation

1. Install Python

2. Clone this repository:

git clone https://github.com/pongiotdevelop/hko_mcp.git

Usage

1. Add the below to your MCP configuration:

{
    "mcpServers": {
        "HKO_MCP": {
            "command": "python",
            "args": [
                "<directory of the project>"
            ]
        }    
    }
}

2. The server provides several tools that can be used by Language Models to query HKO information:

• get_weather_info(dataType: str, lang: str = "en"): Get weather information from the Hong Kong Observatory.
• get_earthquake_info(dataType: str, lang: str = "en"): Get earthquake information from the Hong Kong Observatory.
• Gregorian_Lunar_Calendar_Conversion(date: str): Convert Gregorian date to Lunar date.
• rainfall_past_hour_from_station(lang: str = "en"): Get rainfall past hour from the Hong Kong Observatory.

Testing
