SuperGateway 介绍 MCP Server

What is SuperGateway?

SuperGateway is a gateway tool that converts standard input/output (stdio) into Server-Sent Events (SSE). It allows you to run stdio-based MCP (Model Context Protocol) servers and access them remotely via SSE.

How to use SuperGateway?

Build the project with Maven (Java 17+, Maven 3.6+), then run the JAR with command-line options specifying the stdio command, port, base URL, SSE path, and message path. For example: java -jar supergateway-1.0.0.jar --stdio "java -jar your-mcp-server.jar" --port 8000 --baseUrl http://localhost:8000 --ssePath /sse --messagePath /message.

Key features

• Converts stdio-based MCP servers to SSE services
• Supports multiple simultaneous client connections
• Automatically detects and forwards JSON-formatted output
• Supports CORS
• Includes health check endpoints
• Configurable log levels (info or none)

Use cases

• Remotely accessing a local stdio-based MCP server over HTTP/SSE
• Enabling multiple clients to interact with one MCP server concurrently
• Integrating an MCP server into a web-based architecture
