## Prerequisites ### Prerequisites
1. Clone the repository: First, install `mcp-doris-server`:
```bash
git clone https://github.com/apache/doris-mcp-server.git
cd doris-mcp-server
```
2. Install the latest Python package and copy the environment template:
```bash
pip install mcp-doris-server
cp .env.example .env
vim .env
```
Fill in your Doris FE connection settings in `.env`:
```env
DORIS_HOST=localhost
DORIS_PORT=9030
DORIS_USER=root
DORIS_PASSWORD=
DORIS_DATABASE=information_schema
DORIS_FE_HTTP_PORT=8030
# Optional: custom BE host list
DORIS_BE_HOSTS=
```
```bash
pip install mcp-doris-server
```
## Starting the MCP Server ## Starting the MCP Server
Run the startup script: Run the startup script:
```bash ```bash
./start_server.sh # 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 \

If your Dify deployment requires a public endpoint, use [ngrok](https://ngrok.com): 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.
```bash
ngrok http http://localhost:3000
```

## Prerequisites
1. Clone the repository:
```bash
git clone https://github.com/apache/doris-mcp-server.git
cd doris-mcp-server
````
2. Install the Python package and prepare the environment file:
```bash
pip install mcp-doris-server
cp .env.example .env
vim .env
```
3. In `.env`, set your Doris front-end connection:
```env
DORIS_HOST=localhost
DORIS_PORT=9030
DORIS_USER=root
DORIS_PASSWORD=
DORIS_DATABASE=information_schema
DORIS_FE_HTTP_PORT=8030
# Optional: custom BE host list
DORIS_BE_HOSTS=
```
---
## Installation & Configuration
1. Install the MCP server package:
```bash
pip install mcp-doris-server
```
2. Copy and edit the environment template as shown above.
---
## Starting the MCP Server
Run the startup script:
```bash
./start_server.sh
```
If successful, you will see logs like this:
![Server start logs](../images/dify_start_server.png)
---
## Ngrok Tunnel (Optional)
If your Dify deployment requires a public endpoint, use [ngrok](https://ngrok.com/):
```bash
ngrok http http://localhost:3000
```
Use the generated URL in the plugin configuration.
![Ngrok tunnel](../images/dify_ngrok.png)

## Installing & Configuring the Plugin
1. In the Dify console, go to **Plugin Marketplace**, search for **MCP‑SSE / StreamableHTTP**, and install it.
![Install plugin](../images/dify_install_plugin.png)
2. Click **Configure**, and set the URL (e.g., `https://<your-domain>/mcp`):
```json
{
"doris_mcp_server": {
"transport": "streamable_http",
"url": "https://<your-domain>/mcp"
}
}
```
![Configure plugin](../images/dify_config_mcp.png)
3. Click **Save**. A green **Authorized** indicator should appear:
![Authorized](../images/dify_authorized.png)

## 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 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 calls the MCP tool to run `SHOW TABLES` and returns the list.
![Query tables](../images/dify_query_tabels.png)
### Sales Trend Over Ten Years
* **User**: What has been the sales trend in the `ssb` database over the past ten years, and which year saw the fastest growth?
* **Result**: The tool executes SQL, computes growth rates, and returns a chart or table.
