About SuperGateway

What is SuperGateway: AI-Driven MCP/SSE Orchestration & Real-Time Scaling?

SuperGateway is a versatile orchestration tool that bridges the gap between standard input/output (stdio)-based Model Context Protocol (MCP) servers and modern web clients via Server-Sent Events (SSE). It enables developers to expose MCP servers as real-time, scalable SSE services, empowering seamless integration with web applications. This tool acts as an intelligent middleman, dynamically routing data streams while maintaining compatibility with AI-driven workloads and adaptive scaling requirements.

How to Use SuperGateway: AI-Driven MCP/SSE Orchestration & Real-Time Scaling?

Follow these steps to deploy SuperGateway:

Prepare your MCP server (e.g., Java-based application writing JSON to stdio)
Build the gateway using Maven:
```
cd src/java && mvn clean package
```

Run the gateway with tailored configuration:

java -jar target/supergateway-1.0.0.jar \
  --stdio "your_mcp_command_here" \
  --port 8000 \
  --baseUrl http://yourdomain.com \
  --ssePath /custom_sse

Use the --help flag to explore advanced options like CORS configuration or health-check endpoints.

SuperGateway FAQ

FAQ from SuperGateway: AI-Driven MCP/SSE Orchestration & Real-Time Scaling?

What happens if my MCP server produces non-JSON output?: Only valid JSON messages will be relayed - invalid formats are silently ignored
How do I troubleshoot connection issues?: Enable debug logging via --logLevel none and verify CORS headers match your frontend domain
Can I scale horizontally?: Yes - deploy multiple instances behind a load balancer, though session affinity is required for message consistency
Why use SSE instead of WebSocket?: SSE provides automatic reconnection and simpler server implementation while maintaining one-way real-time communication
Is there a way to throttle message rates?: Use standard server-side rate limiting mechanisms since SuperGateway focuses on protocol conversion

SuperGateway 介绍

这是一个将标准输入/输出（stdio）转换为服务器发送事件（SSE）的网关工具。它允许你运行基于 stdio 的 MCP（Model Context Protocol）服务器，并通过 SSE 进行远程访问。

功能特点

将基于 stdio 的 MCP 服务器转换为 SSE 服务
支持多个客户端同时连接
自动识别和转发 JSON 格式的输出
支持 CORS
支持健康检查端点
可配置的日志级别

系统要求

Java 17 或更高版本
Maven 3.6 或更高版本

构建和运行

构建项目：

cd src/java
mvn clean package

运行应用：

java -jar target/supergateway-1.0.0.jar [选项]

命令行选项

--version: 显示版本号
--stdio: 要运行的 MCP 服务器命令
--sse: SSE URL 连接地址
--port: (stdio→SSE) 服务器监听端口 [默认: 8000]
--baseUrl: (stdio→SSE) SSE 客户端的基础 URL
--ssePath: (stdio→SSE) SSE 订阅路径 [默认: "/sse"]
--messagePath: (stdio→SSE) SSE 消息路径 [默认: "/message"]
--logLevel: 设置日志级别: "info" 或 "none" [默认: "info"]
--cors: 启用 CORS [默认: false]
--healthEndpoint: 添加健康检查端点，多个端点用逗号分隔
--help: 显示帮助信息

使用示例

java -jar target/supergateway-1.0.0.jar \
  --stdio "java -jar your-mcp-server.jar" \
  --port 8000 \
  --baseUrl http://localhost:8000 \
  --ssePath /sse \
  --messagePath /message

API 接口

1. SSE 连接

URL: GET /sse
说明：建立 SSE 连接以接收进程输出
响应：服务器会返回一个 SSE 事件，包含消息发送端点

2. 发送消息

URL: POST /message?sessionId=<session_id>
Content-Type: application/json
说明：向进程发送 JSON 格式的消息
响应：
- 200: 消息发送成功
- 400: 无效的 JSON 消息
- 503: 会话不存在或进程未就绪

3. 健康检查

URL: GET /health (如果配置了健康检查端点)
说明：检查服务是否正常运行
响应：返回 "ok"

注意事项

进程输出必须是 JSON 格式才会被转发到 SSE 客户端
每个 SSE 客户端会自动获得一个唯一的 sessionId
所有消息都必须是有效的 JSON 格式
发送消息时必须使用从 SSE 连接获取的正确 sessionId
MCP 服务器必须支持通过标准输入/输出进行通信
