## 中文

小红书 (Xiaohongshu / REDnote) 数据采集框架 + MCP 服务。

基于 Playwright 实现真实浏览器自动化,具备双层反检测能力(playwright-stealth + browserforge)。通过 MCP 协议将采集能力暴露为标准工具,让 AI 助手(Claude Desktop / Code / Cursor)直接调用。

### 功能特性

- **MCP 服务**:AI 助手可直接搜索小红书、采集笔记详情和评论
- **多种 Transport**:stdio(本地)/ SSE(远程部署)/ Streamable HTTP
- 关键词搜索采集(瀑布流自动滚动加载)
- 笔记详情采集(标题、正文、互动数据、标签、图片/视频)
- 评论采集(Top N 评论,含用户信息和 IP 属地)
- 双层反检测(playwright-stealth 环境级 + browserforge 指纹级)
- 登录状态持久化(扫码登录后自动保存,下次启动免登录)
- 数据输出:JSON(原始完整)+ Excel/xlsx(3 个 Sheet 结构化)
- 生产级稳定性:超时控制、浏览器崩溃自动恢复、登录态失效检测

### 环境要求

- Python 3.10+
- [uv](https://docs.astral.sh/uv/) 包管理器

### 快速开始

```bash
# 1. 克隆仓库
git clone https://github.com/yangsijie666/xiaohongshu-crawler.git && cd xiaohongshu-crawler

# 2. 安装依赖
uv sync

# 3. 安装浏览器
uv run playwright install chromium

# 4. 首次登录(扫码)
uv run python scripts/verify_login.py

# 5. 运行采集
uv run python main.py
```

### MCP 服务使用

#### 方式一:stdio 模式(推荐,本地集成)

在 Claude Desktop 配置文件中添加(Mac: `~/Library/Application Support/Claude/claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "rednote-crawler": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/rednote-crawler", "python", "mcp_server.py"],
      "env": {}
    }
  }
}
```

#### 方式二:SSE 模式(远程部署)

```bash
# 服务器端启动
uv run python mcp_server.py --transport sse --host 0.0.0.0 --port 8000
```

客户端配置:

```json
{
  "mcpServers": {
    "rednote-crawler": {
      "url": "http://your-server:8000/sse"
    }
  }
}
```

#### 方式三:Streamable HTTP 模式

```bash
uv run python mcp_server.py --transport streamable-http --host 0.0.0.0 --port 8000
```

Xiaohongshu (REDnote) data collection framework + MCP server.

Built on Playwright for real browser automation with dual-layer anti-detection (playwright-stealth + browserforge). Exposes collection capabilities as standard MCP tools for AI assistants (Claude Desktop / Code / Cursor).

### Features

- **MCP Server**: AI assistants can directly search REDnote, collect note details and comments
- **Multiple Transports**: stdio (local) / SSE (remote) / Streamable HTTP
- Keyword search with infinite scroll auto-loading
- Note detail collection (title, content, engagement metrics, tags, images/videos)
- Comment collection (Top N comments with user info and IP location)
- Dual-layer anti-detection (environment-level + fingerprint-level)
- Persistent login state (auto-saved after QR code scan)
- Output: JSON (raw) + Excel/xlsx (3-sheet structured)
- Production-grade reliability: timeout control, browser crash auto-recovery, login expiry detection
