如何使用sse协议进行更多的控制，对服务器的配置以及如何处理客户端请求进行细粒度控制？

[zy974400763]

The example given is from STDIO. I would like to ask how to modify SSE?

using ModelContextProtocol.Protocol.Transport;
using ModelContextProtocol.Protocol.Types;
using ModelContextProtocol.Server;
using System.Text.Json;

McpServerOptions options = new()
{
    ServerInfo = new Implementation() { Name = "MyServer", Version = "1.0.0" },
    Capabilities = new ServerCapabilities()
    {
        Tools = new ToolsCapability()
        {
            ListToolsHandler = (request, cancellationToken) =>
                ValueTask.FromResult(new ListToolsResult()
                {
                    Tools =
                    [
                        new Tool()
                        {
                            Name = "echo",
                            Description = "Echoes the input back to the client.",
                            InputSchema = JsonSerializer.Deserialize<JsonElement>("""
                                {
                                    "type": "object",
                                    "properties": {
                                      "message": {
                                        "type": "string",
                                        "description": "The input to echo back"
                                      }
                                    },
                                    "required": ["message"]
                                }
                                """),
                        }
                    ]
                }),

            CallToolHandler = (request, cancellationToken) =>
            {
                if (request.Params?.Name == "echo")
                {
                    if (request.Params.Arguments?.TryGetValue("message", out var message) is not true)
                    {
                        throw new McpException("Missing required argument 'message'");
                    }

                    return ValueTask.FromResult(new CallToolResponse()
                    {
                        Content = [new Content() { Text = $"Echo: {message}", Type = "text" }]
                    });
                }

                throw new McpException($"Unknown tool: '{request.Params?.Name}'");
            },
        }
    },
};

await using IMcpServer server = McpServerFactory.Create(new StdioServerTransport("MyServer"), options);
await server.RunAsync();

I'm not sure if I understand the question. If you're asking how to convert this example to use the (legacy) SSE transport I would refer you to the sample projects under the samples folder in this repo.
