# Publishing mcp-browser with ngrok

The `scripts/run_mcp_ngrok.sh` helper launches `mcp-browser` in
streamable-http mode and exposes it through an ngrok tunnel. By default it uses
the `builtin-only` server profile so only the minimal proxy tools are visible.

```bash
./scripts/run_mcp_ngrok.sh \
  --allow-origin https://platform.openai.com \
  --ngrok-basic-auth "user:pass"
```

Key behaviours:

- Picks a free local port and starts `mcp-browser --mode streamable-http` with
  `--http-path /mcp`.
- Starts `ngrok http` pointing at that port and prints the public URL once the
tunnel is ready.
- Writes logs to temporary files (paths shown on startup).
- Cleans up both processes when interrupted.

Useful options:

- `--server chrome` – publish a different server entry from your config.
- `--config ~/.claude/mcp-browser/config.yaml` – point at a custom config file.
- `--ngrok-region eu` or `--ngrok-domain your-name.ngrok.app` – choose a region
  or reserved domain.
- `--ngrok-basic-auth user:pass` – require HTTP basic auth. Strongly recommended
  if the tunnel is exposed to the public.

Additional `mcp-browser` arguments can be passed after `--`, for example to
connect to a streamable HTTP upstream:

```bash
./scripts/run_mcp_ngrok.sh -- \
  --transport streamable-http \
  --transport-url http://127.0.0.1:12306/mcp
```

The resulting public URL terminates at `/mcp`. Configure your MCP client (e.g.
OpenAI’s MCP interface) with that URL and the optional basic auth credentials.
