An s&box editor addon that runs the editor's MCP server on Linux under Proton. 

The built-in MCP server uses HttpListener, which relies on the Windows http.sys stack that Wine doesn't implement, so it never starts under Proton. This addon serves the same tools over a TcpListener-based HTTP transport instead. Only the transport changes; the tool list comes from the editor's own registry. 

Linux only. On native Windows it stays inactive, since the built-in server already works there.
