About Supergateway

Supergateway is an MCP server published by coding-alt in the Developer Tools category: run MCP stdio servers over SSE and SSE over stdio. AI gateway.

The repository has 7 stars and 4 forks, with the last commit a year ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/coding-alt/supergateway

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

README

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

  1. 构建项目:
cd src/java
mvn clean package
  1. 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

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

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Supergateway safe to use with an AI agent?

Its trust score is 34 out of 100 (low). It passes 2 of the 5 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Supergateway still maintained?

The last commit was a year ago and 1 open issues. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
