Air Pollution

🚀 MCP Server Project

This project is an MCP (Model Context Protocol) server built with Node.js and Express.js, interacting with the OpenWeather API. It allows users to obtain air pollution data based on latitude and longitude or city and country. The backend ensures secure management of API keys through dotenv and efficiently handles API requests.

🚀 Quick Start

This MCP server is designed to interact with the OpenWeather API to provide air pollution data. Here's a brief guide to get you started:

Prerequisites

• Node.js installed on your machine
• An API key from OpenWeather

Installation

1. Clone the repository:

git clone <repository-url>

2. Navigate to the project directory:

cd <project-directory>

3. Install the dependencies:

npm install

4. Create a .env file in the root directory and add your OpenWeather API key:

OPENWEATHER_API_KEY=your_api_key_here

Usage

Start the server:

node app.js

Now you can make requests to the server to get air pollution data. For example, to get data by latitude and longitude:

GET /air-pollution?lat=your_latitude&lon=your_longitude

Or by city and country:

GET /air-pollution?city=your_city&country=your_country

✨ Features

• Data Retrieval: Retrieve air pollution data based on different criteria (latitude/longitude or city/country).
• Secure API Key Management: Use dotenv to securely manage the OpenWeather API key.
• Efficient API Request Handling: The backend efficiently processes requests to the OpenWeather API.

📦 Installation

As described in the Quick Start section, you need to clone the repository, install the dependencies, and set up the .env file with your API key.

💻 Usage Examples

Basic Usage

To get air pollution data by latitude and longitude:

const axios = require('axios');

const lat = 37.7749;
const lon = -122.4194;

axios.get(`http://localhost:3000/air-pollution?lat=${lat}&lon=${lon}`)
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

Advanced Usage

You can also use the server to get data by city and country. Here's an example:

const axios = require('axios');

const city = 'San Francisco';
const country = 'USA';

axios.get(`http://localhost:3000/air-pollution?city=${city}&country=${country}`)
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(error);
  });

🔧 Technical Details

The server is built using Node.js and Express.js. It uses the axios library to make HTTP requests to the OpenWeather API. The API key is securely managed using dotenv. When a request is made to the server, it validates the input parameters and then makes a corresponding request to the OpenWeather API. The response from the API is then processed and sent back to the client.
