Ngrok Tunnel (Optional)

If your Dify deployment requires a publicly accessible endpoint, you can use the ngrok tool. Ngrok is a third-party service that securely exposes local servers to the internet.

Installing & Configuring the Plugin in Dify

In the Dify console, go to Plugin Marketplace, search for, and install MCP‑SSE / StreamableHTTP:
After installation, click Configure and set the URL to your public or local address. For example, if you're using ngrok, this should be the public URL ngrok provides, in the format https://<your-domain>/mcp. If Dify can directly access your local server, use http://localhost:3000/mcp.
```
{
  "doris_mcp_server": {
    "transport": "streamable_http",
    "url": "https://<your-domain>/mcp"
  }
}
```
Click Save. If configured correctly, you'll see a green Authorized indicator:

Creating a Dify App

In the Dify console, click New App → Blank App.
