Dify Example: Integrating Doris MCP Server

This document demonstrates how to integrate and use doris-mcp-server in Dify to perform Doris SQL calls via MCP.

Prerequisites
Starting the MCP Server
Ngrok Tunnel (Optional)
Installing & Configuring the Plugin in Dify
Creating a Dify App
Adding MCP Tools
Example Calls

Prerequisites

First, install mcp-doris-server:

pip install mcp-doris-server

Starting the MCP Server

Run the startup script:

# Full configuration with database connection
doris-mcp-server \
    --transport http \
    --host 0.0.0.0 \
    --port 3000 \
    --db-host 127.0.0.1 \
    --db-port 9030 \
    --db-user root \
    --db-password your_password

If successful, you'll see logs similar to this:

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.
Select Agent as the template and set the App Name (e.g., Doris ChatBI).

Instructions & Tool Configuration

Instruction Block

Paste the following into the Instruction field:

<instruction>
Use MCP tools to complete tasks as much as possible. Carefully read the annotations, method names, and parameter descriptions of each tool. Please follow these steps:
1. Analyze the user's question and match the most appropriate tool.
2. Use tool names and parameters exactly as defined; do not invent new ones.
3. Pass parameters in the required JSON format.
4. When calling tools, use:
   {"mcp_sse_call_tool": {"tool_name": "<tool_name>", "arguments": "{}"}}
5. Output plain text only—no XML tags.
<input>
User question: user_query
</input>
<output>
Return tool results or a final answer, including analysis.
</output>
</instruction>

Adding MCP Tools

In the Tools pane, click Add twice to add two entries, both named mcp_sse (they will inherit the transport and URL from the plugin):

Example Calls

List Tables in Database

User: What tables are in the database?
Result: Dify will call the MCP tool to run SHOW TABLES and return the list.

Sales Trend Over Ten Years

User: What has been the sales trend over the past ten years in the ssb database, and which year had the fastest growth?
Result: The tool will execute the SQL, calculate growth rates, and return data.
