A Simple MCP Server and Client

Okay, here's a simple example of a client-server setup using the Minecraft Communications Protocol (MCP) in Python. This is a very basic illustration and doesn't implement the full Minecraft protocol, but it demonstrates the core concept of sending and receiving data. **Important Considerations:** * **MCP is Complex:** The actual Minecraft protocol is significantly more complex than this example. This is a simplified demonstration. * **Libraries:** For real Minecraft interaction, you'll likely want to use a library like `mcpi` (for Raspberry Pi Minecraft) or a more advanced networking library that handles the protocol details. * **Security:** This example is not secure. Do not use it in a production environment. **Code:** ```python import socket import threading # Server Code class MinecraftServer: def __init__(self, host='localhost', port=25565): self.host = host self.port = port self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.server_socket.bind((self.host, self.port)) self.server_socket.listen(5) # Listen for up to 5 connections self.clients = [] def run(self): print(f"Server listening on {self.host}:{self.port}") while True: client_socket, address = self.server_socket.accept() print(f"Accepted connection from {address}") self.clients.append(client_socket) client_thread = threading.Thread(target=self.handle_client, args=(client_socket,)) client_thread.start() def handle_client(self, client_socket): try: while True: data = client_socket.recv(1024) # Receive up to 1024 bytes if not data: break # Client disconnected message = data.decode('utf-8') print(f"Received from client: {message}") # Echo the message back to the client (simple example) client_socket.sendall(f"Server received: {message}".encode('utf-8')) except Exception as e: print(f"Error handling client: {e}") finally: print("Client disconnected.") self.clients.remove(client_socket) client_socket.close() # Client Code class MinecraftClient: def __init__(self, host='localhost', port=25565): self.host = host self.port = port self.client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) def connect(self): try: self.client_socket.connect((self.host, self.port)) print(f"Connected to server at {self.host}:{self.port}") except Exception as e: print(f"Connection error: {e}") return False return True def send_message(self, message): try: self.client_socket.sendall(message.encode('utf-8')) data = self.client_socket.recv(1024) print(f"Received from server: {data.decode('utf-8')}") except Exception as e: print(f"Send/Receive error: {e}") def close(self): self.client_socket.close() print("Connection closed.") if __name__ == "__main__": # Start the server in a separate thread server = MinecraftServer() server_thread = threading.Thread(target=server.run) server_thread.daemon = True # Allow the main thread to exit even if the server thread is running server_thread.start() # Create a client and connect client = MinecraftClient() if client.connect(): client.send_message("Hello from the client!") client.send_message("Another message.") client.close() ``` **How to Run:** 1. **Save:** Save the code as a Python file (e.g., `mcp_example.py`). 2. **Run:** Execute the file from your terminal: `python mcp_example.py` **Explanation:** * **Server:** * Creates a socket and listens for incoming connections. * When a client connects, it spawns a new thread to handle that client. * The `handle_client` function receives data from the client, prints it, and sends a response back. * **Client:** * Creates a socket and connects to the server. * Sends a message to the server and receives the server's response. * Closes the connection. * **Threading:** The server uses threading so that it can handle multiple clients concurrently. Without threading, the server would only be able to handle one client at a time. * **Encoding:** The code uses UTF-8 encoding to convert strings to bytes for sending over the network and back to strings when receiving. **Important Notes:** * **Error Handling:** The code includes basic error handling (try...except blocks), but you'll want to add more robust error handling in a real application. * **Minecraft Protocol:** This example does *not* implement the actual Minecraft protocol. The real protocol involves specific packet formats, compression, encryption, and authentication. * **Libraries:** For real Minecraft interaction, use a library like `mcpi` (for Raspberry Pi Minecraft) or a more advanced networking library that handles the protocol details. These libraries will handle the complexities of the Minecraft protocol for you. **Translation to Portuguese:** ```python import socket import threading # Código do Servidor class ServidorMinecraft: def __init__(self, host='localhost', port=25565): self.host = host self.port = port self.socket_servidor = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.socket_servidor.bind((self.host, self.port)) self.socket_servidor.listen(5) # Aguarda até 5 conexões self.clientes = [] def executar(self): print(f"Servidor ouvindo em {self.host}:{self.port}") while True: socket_cliente, endereco = self.socket_servidor.accept() print(f"Conexão aceita de {endereco}") self.clientes.append(socket_cliente) thread_cliente = threading.Thread(target=self.lidar_com_cliente, args=(socket_cliente,)) thread_cliente.start() def lidar_com_cliente(self, socket_cliente): try: while True: data = socket_cliente.recv(1024) # Recebe até 1024 bytes if not data: break # Cliente desconectado mensagem = data.decode('utf-8') print(f"Recebido do cliente: {mensagem}") # Envia a mensagem de volta para o cliente (exemplo simples) socket_cliente.sendall(f"Servidor recebeu: {mensagem}".encode('utf-8')) except Exception as e: print(f"Erro ao lidar com o cliente: {e}") finally: print("Cliente desconectado.") self.clientes.remove(socket_cliente) socket_cliente.close() # Código do Cliente class ClienteMinecraft: def __init__(self, host='localhost', port=25565): self.host = host self.port = port self.socket_cliente = socket.socket(socket.AF_INET, socket.SOCK_STREAM) def conectar(self): try: self.socket_cliente.connect((self.host, self.port)) print(f"Conectado ao servidor em {self.host}:{self.port}") except Exception as e: print(f"Erro de conexão: {e}") return False return True def enviar_mensagem(self, mensagem): try: self.socket_cliente.sendall(mensagem.encode('utf-8')) data = self.socket_cliente.recv(1024) print(f"Recebido do servidor: {data.decode('utf-8')}") except Exception as e: print(f"Erro ao enviar/receber: {e}") def fechar(self): self.socket_cliente.close() print("Conexão fechada.") if __name__ == "__main__": # Inicia o servidor em uma thread separada servidor = ServidorMinecraft() thread_servidor = threading.Thread(target=servidor.executar) thread_servidor.daemon = True # Permite que a thread principal termine mesmo que a thread do servidor esteja rodando thread_servidor.start() # Cria um cliente e conecta cliente = ClienteMinecraft() if cliente.conectar(): cliente.enviar_mensagem("Olá do cliente!") cliente.enviar_mensagem("Outra mensagem.") cliente.fechar() ``` **Key Changes in the Portuguese Translation:** * Class names: `MinecraftServer` -> `ServidorMinecraft`, `MinecraftClient` -> `ClienteMinecraft` * Method names: `run` -> `executar`, `handle_client` -> `lidar_com_cliente`, `connect` -> `conectar`, `send_message` -> `enviar_mensagem`, `close` -> `fechar` * Variable names: `server_socket` -> `socket_servidor`, `client_socket` -> `socket_cliente`, `address` -> `endereco`, `message` -> `mensagem` * Print statements: Translated to Portuguese. * Comments: Translated to Portuguese. This translated version should be easier for Portuguese speakers to understand. Remember that the functionality remains the same; only the names and comments have been translated. It's still a simplified example and not a full Minecraft protocol implementation.
