Discover Awesome MCP Servers

McpR

Aqui está uma demonstração de um servidor MCP (Multiplayer Control Protocol) usando SignalR: **Título:** Demonstração de Servidor MCP com SignalR **Descrição:** Esta demonstração ilustra como construir um servidor MCP básico usando o SignalR para comunicação em tempo real entre o servidor e os clientes. O MCP é um protocolo usado para gerenciar e controlar jogos multiplayer, e o SignalR facilita a criação de aplicativos web interativos em tempo real. **Funcionalidades:** * **Conexão e Desconexão de Clientes:** Os clientes podem se conectar e desconectar do servidor. * **Broadcast de Mensagens:** O servidor pode enviar mensagens para todos os clientes conectados. * **Mensagens Privadas:** Os clientes podem enviar mensagens privadas uns para os outros através do servidor. * **Gerenciamento de Jogadores:** O servidor mantém uma lista de jogadores conectados e seus respectivos IDs. * **Comandos Básicos:** Implementação de alguns comandos básicos do MCP, como `/list` (lista os jogadores conectados) e `/whisper [jogador] [mensagem]` (envia uma mensagem privada). **Tecnologias Utilizadas:** * **C#:** Linguagem de programação para o servidor. * **ASP.NET Core:** Framework para construir o servidor web. * **SignalR:** Biblioteca para comunicação em tempo real. * **JavaScript:** Linguagem de programação para o cliente web. * **HTML/CSS:** Para a interface do cliente web. **Estrutura do Projeto:** O projeto consistirá em duas partes principais: 1. **Servidor (C# ASP.NET Core com SignalR):** * Um Hub SignalR que lida com a conexão, desconexão e comunicação dos clientes. * Lógica para gerenciar a lista de jogadores conectados. * Implementação dos comandos básicos do MCP. 2. **Cliente Web (HTML/CSS/JavaScript):** * Uma interface web para conectar ao servidor SignalR. * Campos para inserir mensagens e enviá-las ao servidor. * Uma área para exibir as mensagens recebidas do servidor. **Implementação (Exemplo Simplificado):** **Servidor (C#):** ```csharp using Microsoft.AspNetCore.SignalR; using System.Collections.Generic; using System.Threading.Tasks; public class MCCHub : Hub { private static readonly Dictionary<string, string> ConnectedPlayers = new Dictionary<string, string>(); public override async Task OnConnectedAsync() { string playerId = Context.ConnectionId; ConnectedPlayers.Add(playerId, playerId); // Usando ConnectionId como nome inicial await Clients.All.SendAsync("ReceiveMessage", "Servidor", $"{playerId} entrou no jogo."); await base.OnConnectedAsync(); } public override async Task OnDisconnectedAsync(Exception exception) { string playerId = Context.ConnectionId; ConnectedPlayers.Remove(playerId); await Clients.All.SendAsync("ReceiveMessage", "Servidor", $"{playerId} saiu do jogo."); await base.OnDisconnectedAsync(exception); } public async Task SendMessage(string user, string message) { // Lógica para processar comandos MCP if (message.StartsWith("/")) { await HandleCommand(user, message); } else { await Clients.All.SendAsync("ReceiveMessage", user, message); } } private async Task HandleCommand(string user, string message) { if (message.StartsWith("/list")) { string playerList = string.Join(", ", ConnectedPlayers.Keys); await Clients.Caller.SendAsync("ReceiveMessage", "Servidor", $"Jogadores conectados: {playerList}"); } else if (message.StartsWith("/whisper")) { string[] parts = message.Split(" "); if (parts.Length > 2) { string targetPlayer = parts[1]; string whisperMessage = string.Join(" ", parts.Skip(2)); // Encontrar o ConnectionId do jogador alvo string targetConnectionId = ConnectedPlayers.FirstOrDefault(x => x.Value == targetPlayer).Key; if (targetConnectionId != null) { await Clients.Client(targetConnectionId).SendAsync("ReceiveMessage", user, $"(Whisper) {whisperMessage}"); await Clients.Caller.SendAsync("ReceiveMessage", "Servidor", $"Mensagem enviada para {targetPlayer}."); } else { await Clients.Caller.SendAsync("ReceiveMessage", "Servidor", $"Jogador {targetPlayer} não encontrado."); } } else { await Clients.Caller.SendAsync("ReceiveMessage", "Servidor", "Uso: /whisper [jogador] [mensagem]"); } } else { await Clients.Caller.SendAsync("ReceiveMessage", "Servidor", "Comando desconhecido."); } } public async Task ChangeName(string newName) { string playerId = Context.ConnectionId; ConnectedPlayers[playerId] = newName; await Clients.All.SendAsync("ReceiveMessage", "Servidor", $"{playerId} mudou seu nome para {newName}."); } } ``` **Cliente Web (JavaScript):** ```javascript const connection = new signalR.HubConnectionBuilder() .withUrl("/mccHub") .build(); connection.on("ReceiveMessage", (user, message) => { const li = document.createElement("li"); li.textContent = `${user}: ${message}`; document.getElementById("messagesList").appendChild(li); }); connection.start().then(() => { console.log("Conectado ao servidor SignalR."); document.getElementById("sendButton").disabled = false; }).catch(err => console.error(err.toString())); document.getElementById("sendButton").addEventListener("click", event => { const user = document.getElementById("userInput").value; const message = document.getElementById("messageInput").value; connection.invoke("SendMessage", user, message).catch(err => console.error(err.toString())); event.preventDefault(); }); document.getElementById("changeNameButton").addEventListener("click", event => { const newName = document.getElementById("newNameInput").value; connection.invoke("ChangeName", newName).catch(err => console.error(err.toString())); event.preventDefault(); }); ``` **Considerações:** * Este é um exemplo simplificado e precisa de mais tratamento de erros, segurança e funcionalidades para ser um servidor MCP completo. * A lógica de gerenciamento de jogadores pode ser expandida para incluir informações adicionais, como pontuação, nível, etc. * Os comandos MCP podem ser estendidos para suportar mais funcionalidades do jogo. * A interface do cliente web pode ser aprimorada para fornecer uma melhor experiência do usuário. * A segurança deve ser considerada, especialmente ao lidar com informações sensíveis. **Próximos Passos:** 1. Crie um projeto ASP.NET Core Web API. 2. Instale o pacote NuGet `Microsoft.AspNetCore.SignalR.Core`. 3. Configure o SignalR no `Startup.cs`. 4. Crie o Hub SignalR (como o `MCCHub` acima). 5. Crie a interface do cliente web (HTML/CSS/JavaScript). 6. Implemente a lógica de conexão, envio e recebimento de mensagens no cliente web. 7. Teste e depure o aplicativo. Este exemplo fornece um ponto de partida para construir um servidor MCP usando SignalR. Você pode expandir e adaptar este código para atender às suas necessidades específicas. Lembre-se de considerar a segurança e o tratamento de erros ao desenvolver um aplicativo de produção.
