🧠 Custom MCP Server Demo

🧠 Custom MCP Server Demo

This project is a Custom MCP (Model Context Protocol) Server built using Python, It’s designed to demonstrate how to create a custom server that communicates using the Model Context Protocol (MCP) — a simple, custom-designed protocol useful for building flexible communication systems between clients and servers.

📌 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 the server

• Manage client connections and message handling in a structured way

• Send and receive custom commands and data with context-aware processing

It is a learning base for creating more complex client-server systems, such as multiplayer games, chat applications, or custom networked tools.

🚀 Features

• 🌐 TCP-based custom server built in Python

• 🔄 Model Context Protocol: structured message handling

• 📡 Real-time communication between client and server

• 🧩 Easy to extend with new message types or functionalities

• 🧪 Great for learning networking, protocol design, and server architecture

🔧 Requirements

• Python 3.8+

• Basic understanding 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
   

💡 How the Protocol Works (MCP)

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

1. A model: What kind of data is being sent (e.g., "chat", "move", "state")

2. A context: Additional metadata to help interpret the model

3. The 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 responds accordingly, making it easy to handle multiple types of client interactions in a clean and scalable way.
