## 快速开始

### 安装

#### 使用uv安装（推荐）

```bash
# 从PyPI安装
uv add poly-query-mcp

# 或者从GitHub安装
uv add git+https://github.com/yourusername/poly-query-mcp.git

# 或者使用uvx直接运行
uvx poly-query-mcp
```

#### 传统安装方式

1. 克隆仓库
```bash
git clone <repository-url>
cd poly_query_mcp
```

2. 创建虚拟环境
```bash
python -m venv .venv
.venv\Scripts\activate  # Windows
source .venv/bin/activate  # Linux/Mac
```

3. 安装依赖
```bash
pip install -r requirements.txt
```

### 配置

1. 复制示例配置文件
```bash
cp config.json config.json
```

2. 编辑配置文件，添加您的数据库连接信息

### 使用

启动MCP服务器：
```bash
# 使用uvx
uvx poly-query-mcp

# 或者传统方式
python main.py
```

mcp接入使用：
1. 在支持mcp client中（如Claude Desktop）的配置文件中添加此MCP服务器（参考下面完整的mcp的数据库配置）：

```json
{
  "mcpServers": {
    "poly-query-mcp": {
      "command": "uvx",
      "args": [
        "poly-query-mcp",
        "--mysql-host", "localhost",
        "--mysql-port", "3306",
        "--mysql-user", "root",
        "--mysql-password", "your_mysql_password",
        "--mysql-database", "your_mysql_database"
      ]
    }
  }
}
```

1. 重启mcp服务
2. 在对话中使用数据库查询功能

更多安装和配置选项请参考 [uv安装指南](docs/UV_INSTALLATION.md)
