## Preview
### Architecture
There are two ways to integrate this server in your project, as shown below:
The left is remote mode, which is the default mode. It requires an API key to access the xiyanSQL-qwencoder-32B model from service provider (see [Configuration](#Configuration)).
Another mode is local mode, which is more secure. It does not require an API key.

### Best practice
[Build a local data assistant using MCP + Modelscope API-Inference without writing a single line of code](https://mp.weixin.qq.com/s/tzDelu0W4w6t9C0_yYRbHA)
### Tools Preview
- The tool ``get_data`` provides a natural language interface for retrieving data from a database. This server will convert the input natural language into SQL using a built-in model and call the database to return the query results.
- The ``{dialect}://{table_name}`` resource allows obtaining a portion of sample data from the database for model reference when a specific table_name is specified.
- The ``{dialect}://`` resource will list the names of the current databases
## Installation
### Installing from pip
Python 3.11+ is required.
You can install the server through pip, and it will install the latest version:
```bash
pip install xiyan-mcp-server
```
After that you can directly run the server by:
```bash
python -m xiyan_mcp_server
```
But it does not provide any functions until you complete following config.
You will get a yml file. After that you can run the server by:
```yaml
env YML=path/to/yml python -m xiyan_mcp_server
```
### Installing from Smithery.ai
See [@XGenerationLab/xiyan_mcp_server](https://smithery.ai/server/@XGenerationLab/xiyan_mcp_server)
Not fully tested.
## Configuration
You need a YAML config file to configure the server.
A default config file is provided in config_demo.yml which looks like this:
```yaml
model:
name: "XGenerationLab/XiYanSQL-QwenCoder-32B-2412"
key: ""
url: "https://api-inference.modelscope.cn/v1/"
database:
host: "localhost"
port: 3306
user: "root"
password: ""
database: ""
```
### LLM Configuration
``Name`` is the name of the model to use, ``key`` is the API key of the model, ``url`` is the API url of the model. We support following models.
| versions | general LLMs(GPT,qwenmax) | SOTA model by Modelscope | SOTA model by Dashscope | Local LLMs |
|----------|-------------------------------|--------------------------------------------|-----------------------------------------------------------|-----------------------|
| description| basic, easy to use | best performance, stable, recommand | best performance, for trial | slow, high-security |
| name | the official model name (e.g. gpt-3.5-turbo,qwen-max) | XGenerationLab/XiYanSQL-QwenCoder-32B-2412 | xiyansql-qwencoder-32b | xiyansql-qwencoder-3b |
| key | the API key of the service provider (e.g. OpenAI, Alibaba Cloud) | the API key of modelscope | the API key via email | "" |
| url | the endpoint of the service provider (e.g."https://api.openai.com/v1") | https://api-inference.modelscope.cn/v1/ | https://xiyan-stream.biz.aliyun.com/service/api/xiyan-sql | http://localhost:5090 |
#### General LLMs
If you want to use the general LLMs, e.g. gpt3.5, you can directly config like this:
```yaml
model:
name: "gpt-3.5-turbo"
key: "YOUR KEY "
url: "https://api.openai.com/v1"
database:
```
If you want to use Qwen from Alibaba, e.g. Qwen-max, you can use following config:
```yaml
model:
name: "qwen-max"
key: "YOUR KEY "
url: "https://dashscope.aliyuncs.com/compatible-mode/v1"
database:
```
#### Text-to-SQL SOTA model
We recommend the XiYanSQL-qwencoder-32B (https://github.com/XGenerationLab/XiYanSQL-QwenCoder), which is the SOTA model in text-to-sql, see [Bird benchmark](https://bird-bench.github.io/).
There are two ways to use the model. You can use either of them.
(1) [Modelscope](https://www.modelscope.cn/models/XGenerationLab/XiYanSQL-QwenCoder-32B-2412), (2) Alibaba Cloud DashScope.
##### (1) Modelscope version
You need to apply a ``key`` of API-inference from Modelscope, https://www.modelscope.cn/docs/model-service/API-Inference/intro
Then you can use the following config:
```yaml
model:
name: "XGenerationLab/XiYanSQL-QwenCoder-32B-2412"
key: ""
url: "https://api-inference.modelscope.cn/v1/"
```
Read our [model description](https://www.modelscope.cn/models/XGenerationLab/XiYanSQL-QwenCoder-32B-2412) for more details.
##### (2) Dashscope version
We deployed the model on Alibaba Cloud DashScope, so you need to set the following environment variables:
Send me your email to get the ``key``. ( godot.lzl@alibaba-inc.com )
In the email, please attach the following information:
```yaml
name: "YOUR NAME",
email: "YOUR EMAIL",
organization: "your college or Company or Organization"
```
We will send you a ``key`` according to your email. And you can fill the ``key`` in the yml file.
The ``key`` will be expired by 1 month or 200 queries or other legal restrictions.
```yaml
model:
name: "xiyansql-qwencoder-32b"
key: "KEY"
url: "https://xiyan-stream.biz.aliyun.com/service/api/xiyan-sql"
database:
```
Note: this model service is just for trial, if you need to use it in production, please contact us.
Alternatively, you can also deploy the model [XiYanSQL-qwencoder-32B](https://github.com/XGenerationLab/XiYanSQL-QwenCoder) on your own server.
#### Local Model
Note: the local model is slow (about 12 seconds per query on my macbook).
If you need a stable and fast service, we still recommend to use the modelscope version.
To run xiyan_mcp_server in local mode, you need
1) a PC/Mac with at least 16GB RAM
2) 6GB disk space
Step 1: Install additional Python packages
```bash
pip install flask modelscope torch==2.2.2 accelerate>=0.26.0 numpy=2.2.3
```
Step 2: (optional) manually download the model
We recommend [xiyansql-qwencoder-3b](https://www.modelscope.cn/models/XGenerationLab/XiYanSQL-QwenCoder-3B-2502/).
You can manually download the model by
```bash
modelscope download --model XGenerationLab/XiYanSQL-QwenCoder-3B-2502
```
It will take you 6GB disk space.
Step 3: download the script and run server. src/xiyan_mcp_server/local_xiyan_server.py
```bash
python local_xiyan_server.py
```
The server will be running on http://localhost:5090/
Step 4: prepare config and run xiyan_mcp_server
the config.yml should be like:
```yml
model:
name: "xiyansql-qwencoder-3b"
key: "KEY"
url: "http://127.0.0.1:5090"
```
Till now the local mode is ready.
### Database Configuration
``host``, ``port``, ``user``, ``password``, ``database`` are the connection information of the database.
You can use local or any remote databases. Now we support MySQL and PostgreSQL(more dialects soon).
#### MySQL
```yaml
database:
host: "localhost"
port: 3306
user: "root"
password: ""
database: ""
```
#### PostgreSQL
Step 1: Install Python packages
```bash
pip install psycopg2
```
Step 2: prepare the config.yml like this:
```yaml
database:
dialect: "postgresql"
host: "localhost"
port: 5432
user: ""
password: ""
database: ""
```
Note that ``dialect`` should be ``postgresql`` for postgresql.
## Launch
### Claude Desktop
Add this in your Claude Desktop config file, ref <a href="https://github.com/XGenerationLab/xiyan_mcp_server/blob/main/imgs/claude_desktop.jpg">Claude Desktop config example</a>
```json
{
"mcpServers": {
"xiyan-mcp-server": {
"command": "python",
"args": [
"-m",
"xiyan_mcp_server"
],
"env": {
"YML": "PATH/TO/YML"
}
}
}
}
```
### Cline
Prepare the config like [Claude Desktop](#claude-desktop)
### Goose
Add following command in the config, ref <a href="https://github.com/XGenerationLab/xiyan_mcp_server/blob/main/imgs/goose.jpg">Goose config example</a>
```yaml
env YML=path/to/yml python -m xiyan_mcp_server
```
### Cursor
Use the same command like [Goose](#goose).
### Witsy
Add following in command:
```yaml
python -m xiyan_mcp_server
```
Add an env: key is YML and value is the path to your yml file.
