### Description (declared)

# Web Search MCP Server

多源网页搜索 MCP 服务器，支持自动故障转移。专为国内用户优化，无需 VPN 即可使用。

## 特性

- **VPN 自动检测**: 自动检测网络环境，开启 VPN 用国际源，未开启用国内源
- **多搜索源支持**: 国内源（必应中国、百度、搜狗、360）+ 国际源（DuckDuckGo、Google News、Wikipedia）
- **自动故障转移**: 如果一个源失败，自动尝试下一个
- **语言检测**: 自动为中日韩文查询调整搜索参数
- **灵活输出**: 文本（人类可读）或 JSON（结构化）格式
- **网页抓取**: 从 URL 提取可读内容
- **无需 API Key**: 所有搜索源均为免费

## 安装

```bash
# 从源码安装
pip install -e .

# 或使用 uv
uv pip install -e .
```

## 搜索源

| 源 | 描述 | 国内可用 |
|-----|------|---------|
| `bing_china` | 必应中国 (cn.bing.com) | ✅ |
| `baidu` | 百度搜索 | ✅ |
| `sogou` | 搜狗搜索 | ✅ |
| `so360` | 360搜索 (so.com) | ✅ |
| `ddg_lite` | DuckDuckGo Lite | ❌ 需VPN |
| `google_news_rss` | Google News RSS | ❌ 需VPN |
| `wikipedia` | Wikipedia OpenSearch | ❌ 需VPN |

### 默认优先级

**自动检测 VPN 状态：**

- **VPN 开启**: DuckDuckGo → Google News → Wikipedia → 必应中国 → 百度 → 搜狗 → 360
- **VPN 关闭**: 必应中国 → 百度 → 搜狗 → 360

首次搜索时会自动检测网络环境（尝试访问 Google），结果会缓存避免重复检测。

## 使用

### 运行服务器

```bash
# 直接执行
mcpcn-web-search-mcp

# 或通过 Python
python -m web_search_mcp.server
```
