What is the Custom MCP Server?
The Custom MCP Server is a Python-based demonstration server that implements the Model Context Protocol (MCP) - a simple custom protocol designed for flexible communication between clients and servers. It serves as a foundation for building various networked applications like chat systems, multiplayer games, or custom tools.How to use the MCP Server?
The server is easy to set up and run. After installation, it listens for client connections and processes messages following the MCP format. Clients can send structured messages containing model, context, and data components.Ideal Use Cases
Perfect for developers learning networking concepts, prototyping communication systems, or building small-scale networked applications that require structured message handling.Key Features
Custom Protocol ImplementationImplements the Model Context Protocol (MCP) for structured message handling between clients and server.
Python-based ServerBuilt using Python's socket library for reliable TCP communication.
Extensible ArchitectureEasy to extend with new message types and functionalities for different use cases.
Real-time CommunicationSupports real-time bidirectional communication between client and server.
Pros and Cons
Advantages
Simple and clean protocol design for learning purposes
No external dependencies required
Easy to understand and modify codebase
Great foundation for building custom networked applications
Limitations
Basic implementation not suitable for production use without enhancements
Limited security features in the demo version
No built-in support for multiple simultaneous complex operations
Getting Started
Clone the repositoryGet the source code from GitHub
Run the serverStart the MCP server using Python
Connect a clientUse any TCP client to connect to the server (default port: 5555)
Example Use Cases
Simple Chat ApplicationBuilding a basic chat system where users can send and receive messages
Game Server PrototypeCreating a simple multiplayer game server that tracks player positions
Frequently Asked Questions
1
What is MCP (Model Context Protocol)?MCP is a simple custom protocol where messages contain three components: model (data type), context (metadata), and data (actual content). This structure makes message handling more organized.
2
Can I use this in production?This is primarily a learning/demonstration project. For production use, you would need to add security, error handling, and potentially scale the implementation.
3
How do I extend the server with new features?You can add new message handlers by following the existing pattern in the code. Each new 'model' type can have its own processing logic.
