How to add extra headers in sse client requests. #434

I am testing a mcp server and routing the requests to local mcp server through a ngrok tunnel. Now the requests through ngrok has to have this header:

{
    "ngrok-skip-browser-warning": "69420",
}

the value can be anything actually.

Normally I am doing all the fetch requests like this:

const response = await fetch(url, {
    method: 'GET', headers: new Headers({
      "ngrok-skip-browser-warning": "69420",
    }),
  });

How do I add it to my sse transport? This following method is not actually adding the header to the requests.

this.transport = new SSEClientTransport(new URL(url), {
      requestInit: {
        headers: {
          "ngrok-skip-browser-warning": "69420",
        }
      }
    });

I see an issue in the current implementation.. It is not considering the requestInit headers..
