Timeouts when connecting?

Hi, we've been trying to integrate with the "/sse" endpoint on the server with ngrok. The client library we've been using in our Go application is "github.com/mark3labs/mcp-go", which seems to work with other SSE servers. When looking at the output from connecting with a browser, it seems different than mcp-proxy. Is this designed specifically for Cline or will it work with other MCP clients?
