MCP Gateway

MCP Gateway gives your local MCP server a stable public HTTPS URL.

You run a small CLI agent on your machine. It opens a WebSocket to the gateway and forwards every incoming HTTP request from https://<id>.mcp-gateway.info straight to your local process. No firewall changes, no DNS, no reverse proxy.

How it works​

┌──────────────┐  HTTPS  ┌─────────────────┐  WebSocket  ┌──────────────────┐
│  MCP client  │ ──────► │  mcp-gateway.info│ ◄────────► │ mcp-gw agent     │
│  (Claude,    │         │                 │             │  + your local    │
│   Cursor...) │         │                 │             │    MCP server    │
└──────────────┘         └─────────────────┘             └──────────────────┘

You only need:

  • Node.js 20+ on your machine
  • A local MCP server reachable on http://localhost:<port>

The CLI registers a free account for you automatically on first run — no manual signup. The admin UI is optional, for browsing request logs.

What you get​

  • A stable URL: https://<your-tunnel>.mcp-gateway.info
  • Works with any MCP-compatible client (Claude Desktop, Cursor, custom apps)
  • Per-request logs in the admin UI (method, path, status, duration)
  • Token-based auth — only your agent can use the tunnel
