Fail to connect with mongodb local mcp server setup using docker

[saadshaikh3]

I am using docker to set up a container of mongodb mcp server. It starts properly and the docker logs also indicate the restricted tools as I also pass the read only env.
Here are the docker logs:

As I started the docker container I specified the ports to be 9091:8080 so now my MCP server is available at http://localhost:9091. But I have tried every possible way to connect to it, but I cannot figure out how I can, i remotely connect to this local MCP server from a local client.

I even tried to connect using MCP Inspector using http protocol but still got the following error:

Received POST message for sessionId undefined

      remoteFamily: 'IPv6',
      timeout: undefined,
      bytesWritten: 463,
      bytesRead: 0
    }
  }
}

So I am not really sure whats going on.

What's the transport protocol for the mongodb mcp server?
Is there a default port?

I can't find any documentation on connecting remotely to this locally setup mongo mcp server
