## What it is
Supergateway is a CLI tool that runs MCP stdio-based servers over SSE, WebSockets, or Streamable HTTP, and vice versa, with a single command. It acts as a transport bridge/gateway for Model Context Protocol servers, enabling remote access and debugging.

## Use cases
- expose a local MCP stdio server over SSE for remote access
- connect an SSE-based MCP server to a stdio-only client
- debug MCP server communication over HTTP transports
- add CORS and health endpoints to an MCP server
- bridge stdio MCP servers to Streamable HTTP
- secure MCP gateway with bearer token auth headers

## When to choose
- your MCP server only supports stdio but clients need SSE, WS, or Streamable HTTP access
- you need to remotely access or share a local MCP server
- you want a quick one-command transport bridge for MCP debugging

## When to avoid
- you need a full production API gateway with rate limiting and load balancing
- your MCP server already natively supports SSE or Streamable HTTP
- you need MCP server hosting rather than transport conversion
