Custom MCP Server Python

🚀 Custom MCP Server Demo

This project is a custom MCP (Model Context Protocol) server built with Python, aiming to demonstrate how to create a custom server that uses a self - designed protocol (MCP) for communication. MCP is a simple and flexible protocol suitable for building communication systems between clients and servers.

🚀 Quick Start

Prerequisites

• Python 3.8+
• Basic knowledge of networking (sockets, TCP)
• No external dependencies required

How to Run

1. Clone the repository:

git clone https://github.com/Eltaf-azizi/Custom-MCP-Server-Demo.git
cd custom-mcp-server

2. Run the server:

python server.py

✨ Features

• 🌐 A custom Python server based on TCP
• 🔄 Model Context Protocol: Structured message handling
• 📡 Real - time communication between clients and servers
• 🧩 Easy to extend with new message types or features
• 🧪 An ideal foundation for learning about networking, protocol design, and server architecture

What is this project about?

This project helps you understand how to:

• Build a custom server using Python's socket library
• Implement a custom protocol (MCP) to handle communication between clients and servers
• Manage client connections and message processing in a structured way
• Send and receive custom commands and data with context - aware processing

It serves as a basic learning platform for building more complex client - server systems, such as multiplayer games, chat applications, or custom network tools.

How the protocol (MCP) works

The Model Context Protocol is a custom - defined protocol where each message includes:

1. Model: The type of data being sent (e.g., "chat", "move", "status")
2. Context: Additional metadata to help interpret the model
3. Data: The actual payload/message

Example message structure (as JSON over TCP):

{
    "model": "chat",
    "context": "user",
    "data": "Hello, world!"
}

The server parses these messages and processes them accordingly, making it easy to handle various types of client interactions in a clean and extensible manner.
