## 🚀 Quick Start

### Prerequisites

- Python 3.10 or higher
- [uv](https://github.com/astral-sh/uv) (recommended) or pip
- DashScope API key (for AI search features)

### Installation

#### Using uv (Recommended)

```bash
# Clone the repository
git clone https://github.com/Vist233/Google-Search-Tool.git
cd search-mcp

# Install with uv
uv pip install -e .
```

#### Using pip

```bash
pip install -e .
```

### Environment Setup

Create a `.env` file or set environment variables for AI features:

```bash
export DASHSCOPE_API_KEY="your-api-key-here"
```

## 📖 Usage

### As an MCP Server

Add to your MCP client configuration (e.g., Claude Desktop):

**For macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`

**For Windows**: `%APPDATA%/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "search-tools": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/search-mcp/searcher/src",
        "run",
        "python",
        "server.py"
      ]
    }
  }
}
```

Alternatively, if installed globally:

```json
{
  "mcpServers": {
    "search-tools": {
      "command": "python",
      "args": [
        "-m",
        "searcher.src.server"
      ],
      "cwd": "/path/to/search-mcp"
    }
  }
}
```

```bash
cd searcher/src
python server.py
```
