supergateway

Supergateway facilitates the operation of MCP stdio-based servers over Server-Sent Events (SSE) or WebSockets (WS) with a simple command-line interface, enhancing remote access and debugging capabilities. Its notable features include support for multiple output transports, integration with authentication headers, customizable session management, and comprehensive logging options. This tool is particularly valuable for developers needing to connect legacy MCP servers that only support stdio with modern web protocols.
