Overview

Supergateway

Main Purpose: Supergateway is a tool that allows you to run MCP (Model Context Protocol) stdio-based servers over Server-Sent Events (SSE). This is particularly useful for remote access, debugging, or connecting to SSE-based clients when your MCP server only supports stdio.

Key Features:

• Exposes an SSE-based interface for your MCP stdio server
• Supports running MCP servers with a single command
• Integrates with tools like MCP Inspector for remote access and management
• Allows you to use ngrok to share your local MCP server with remote clients

Target Audience and Use Cases:

• Developers who work with MCP-based AI tools and need to expose their stdio-based servers to remote clients
• Researchers and engineers who need to debug or remotely access their MCP servers
• Teams building SSE-based applications that need to integrate with MCP-powered services

Uniqueness and Noteworthiness: Supergateway is a unique solution that bridges the gap between MCP stdio servers and SSE-based clients. By providing a simple and straightforward way to expose stdio servers over SSE, it simplifies the process of connecting remote tools and clients to your MCP-based infrastructure.

Configuration Example

{
  "mcpServers": {
    "supergateway": {
      "command": "npx",
      "args": [
        "-y",
        "supergateway",
        "--stdio",
        "uvx mcp-server-git"
      ],
      "env": {
        "PORT": "8000"
      }
    }
  }
}

Technical Implementation

Installation
