Supergateway MCP Gateway

Example Use Cases

• 1

  Expose a local MCP stdio server over SSE so web clients can subscribe to events and send messages remotely.

• 2

  Connect a remote SSE-based MCP and bridge it into local stdio tools (SSE→stdio) for CLI integration and debugging.

• 3

  Host an MCP over WebSockets or integrate stdio MCP servers with tools like Claude Desktop, Cursor, or Supermachine.

Description

Supergateway runs MCP (Model Context Protocol) stdio servers over SSE (Server-Sent Events) or WebSockets with a single command, supporting stdio→SSE, SSE→stdio, and stdio→WS modes. It can be run via npx or Docker, forwards headers and OAuth2 bearer tokens, supports CORS and health endpoints, and is useful for integrating local or remote MCPs with web-based tools. The tool is designed for debugging, remote access, and connecting stdio-only MCP servers to clients such as Supermachine, Claude Desktop, or Cursor.
