Using Cursor and MCP to Communicate and Clone Web Applications

Explore how Cursor and MCP enable seamless communication and cloning of web applications. Learn how these technologies streamline data synchronization and integration across platforms.

Using Cursor and MCP to Communicate and Clone Web Applications

In modern software development, efficient communication between web applications is crucial. Cursor and MCP (Message Communication Protocol) enable seamless interactions between different web apps, allowing developers to clone, synchronize, or integrate functionalities across platforms. In this article, we will explore how to use these technologies in Python with working code examples.

Understanding Cursor and MCP

Together, these technologies allow applications to clone functionalities and exchange data efficiently.

Setting Up MCP for Communication

We can use a WebSocket-based implementation of MCP to facilitate real-time communication between web applications. Let’s implement a simple server-client communication system.

Installing Required Libraries

Ensure you have the necessary dependencies installed:

pip install websockets asyncio requests

MCP Server Implementation

The MCP server will act as the central hub for message passing between applications.

import asyncio
import websockets

clients = set()

async def handler(websocket, path):
    clients.add(websocket)
    try:
        async for message in websocket:
            print(f"Received: {message}")
            for client in clients:
                if client != websocket:
                    await client.send(message)
    finally:
        clients.remove(websocket)

start_server = websockets.serve(handler, "localhost", 8765)

asyncio.get_event_loop().run_until_complete(start_server)
asyncio.get_event_loop().run_forever()

MCP Client Implementation

Now, let’s create a client that can communicate with the MCP server.

import asyncio
import websockets

async def send_message():
    async with websockets.connect("ws://localhost:8765") as websocket:
        while True:
            message = input("Enter message: ")
            await websocket.send(message)
            response = await websocket.recv()
            print(f"Received: {response}")

asyncio.run(send_message())

With this setup, multiple clients can communicate with each other via the MCP server.

Using Cursor to Clone Web Apps

Cursor can be used to automate interactions and extract data from web applications. Below is a simple Python script using requests and BeautifulSoup to clone basic content from a webpage.

Installing Dependencies

pip install beautifulsoup4 requests

Cloning a Web Page with Cursor

import requests
from bs4 import BeautifulSoup

def clone_website(url):
    response = requests.get(url)
    if response.status_code == 200:
        soup = BeautifulSoup(response.text, 'html.parser')
        with open("cloned_page.html", "w", encoding="utf-8") as file:
            file.write(soup.prettify())
        print("Website cloned successfully!")
    else:
        print("Failed to retrieve the webpage.")

clone_website("https://example.com")

This script fetches the HTML content of a website and saves it locally.

Conclusion

By combining Cursor for web automation and MCP for structured communication, developers can build sophisticated systems that interact seamlessly with different web applications. Whether it’s for web scraping, data synchronization, or cloning web functionalities, these tools offer powerful capabilities for modern applications.
