I’ve just released Supergateway and it allows to use MCP servers with stdio on remote assistants over SSE.
Now most of MCP servers only support stdio transport and this is problematic if you want remote assistants to access them. MCP spec has SSE transport which works with remote HTTP connections but it is rarely used by MCP server authors. So I’ve created this gateway that allows you to run stdio transport MCP servers and tunnel them via SSE transport.
It’s very simple to use. Run any stdio MCP server like this:
npx -y supergateway --stdio "uvx mcp-server-git"
It’s totally open-source and supports pretty much any MCP server.
Built this since we have an AI infrastructure platform (https://superinterface.ai) that allows you to use MCP servers in remote assistants and we saw that we cannot really run any community MCP servers without something like this.
It’s def pretty cool to see remote assistants embedded on a website being able to access these cool MCP servers.
Let me know what you think!
