Any MCP client

Public URLs for localhost, from inside Any MCP client.

rustunnel-mcp is a Model Context Protocol server for tunnels: any MCP-compatible agent can create, list, and close public tunnels to localhost with six dedicated tools.

1. Install

installs rustunnel (CLI) + rustunnel-mcp (MCP server)

brew tap joaoh82/rustunnel && brew install rustunnel

2. Get an API token

Sign up free at rustunnel.com and create a key under Dashboard → API Keys. Self-hosting? Generate a token on your own server. Either way, it goes in RUSTUNNEL_TOKEN below — you never paste it into chat.

3. Connect Any MCP client

your MCP client's server config

{
  "mcpServers": {
    "rustunnel": {
      "command": "rustunnel-mcp",
      "args": [
        "--server", "eu.edge.rustunnel.com:4040",
        "--api", "https://eu.edge.rustunnel.com:8443"
      ],
      "env": { "RUSTUNNEL_TOKEN": "<your-token>" }
    }
  }
}

4. Ask for a tunnel

Paste this prompt (or just describe what you need — the agent picks the right tool):

I need a public HTTPS URL for my localhost:3000 server. Use rustunnel — its MCP tools or the rustunnel CLI — to open the tunnel and give me the public URL when it's ready.

The agent gets six tools — create_tunnel, list_tunnels, close_tunnel, get_connection_info, list_regions, and get_tunnel_history — covering HTTP, TCP, and UDP tunnels, custom subdomains, regions, P2P, and load-balanced pools with health checks.
