MCP

In this guide, we demonstrate how to use the NoPorts Tunnel to securely access an MCP server running on a remote device, making it accessible via localhost:3001 on your local machine

In this example, we assume the OpenAPI-based MCP Server is listening on port 3000. These instructions apply to other MCP server types as well, not just OpenAPI-based deployments.

Command Line

The command should look like:

npt -f @<client> -t @<device> -d <device name> -r @<relay> -p 3001 -l 3000

Example:

npt -f @alice_client -t @alice_device -d my_server -r @rv_am -p 3001 -l 3000

Now you can interact with your OpenAPI-based MCP server by connecting to http://localhost:3001 .

Device Name	my_server
Relay	@rv_am
Local Port	3001
Remote Host	localhost
Remote Port	3000
