-# 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:
-
-![Server start logs](../images/dify_start_server.png)
-
------
-
-## 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**:
- ![Install plugin](../images/dify_install_plugin.png)
-
-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"
-      }
-    }
-    ```
-     ![Configure plugin](../images/dify_config_mcp.png)
-
-3.  Click **Save**. If configured correctly, you'll see a green **Authorized** indicator:
-
-   ![Authorized](../images/dify_authorized.png)
-
------
-
-## Creating a Dify App
-
-1.  In the Dify console, click **New App** → **Blank App**.
-![Create app](../images/dify_create_app.png)
-
-2.  Select **Agent** as the template and set the **App Name** (e.g., `Doris ChatBI`).
-![Agent setup](../images/dify_agent_setup.png)
-
-
-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):
-![Add tools](../images/dify_add_tools.png)
-
------
-
-## 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.
-  ![Query tables](../images/dify_query_tabels.png)
-
-### 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.
