# 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
First, install `mcp-doris-server`:
```bash
pip install mcp-doris-server
```
## Starting the MCP Server
Run the startup script:
```bash
# 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
1. In the Dify console, go to **Plugin Marketplace**, search for, and install **MCP‑SSE / StreamableHTTP**:

2. 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`.
```json
{
"doris_mcp_server": {
"transport": "streamable_http",
"url": "https://<your-domain>/mcp"
}
}
```

3. Click **Save**. If configured correctly, you'll see a green **Authorized** indicator:

-----
## Creating a Dify App
1. In the Dify console, click **New App** → **Blank App**.

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

3. Import from DSL,[dify_doris_dsl.yml](dify_doris_dsl.yml)
-----
## 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.
