Converts WeChat Official Account articles to clean Markdown with locally downloaded images, supporting single and batch operations via MCP tools.

README

English

A modular Python tool that converts WeChat Official Account (微信公众号) articles into clean Markdown files with locally downloaded images. Designed for both human use (CLI) and AI agent integration (MCP server + SKILL.md).

Features

  • Anti-detection scraping — Uses Camoufox (stealth Firefox) to bypass WeChat's bot detection
  • Smart page loadingnetworkidle wait instead of hardcoded sleep
  • Retry logic — 3× exponential backoff for page fetching, 3× linear backoff for image downloads
  • CAPTCHA detection — Explicit detection with actionable error messages
  • Batch processing — Multiple URLs via args or file input
  • Image localization — Concurrent async downloads with Content-Type based extension inference
  • Code block preservation — Language detection, CSS counter garbage filtering
  • Media extraction — Handles WeChat's <mpvoice> audio and <mpvideo> video elements
  • YAML frontmatter — Structured metadata (title, author, date, source)
  • MCP server — Expose as tools for any MCP-compatible AI client
  • SKILL.md — Ready for Claude Code skill integration

Installation

git clone https://github.com/bzd6661/wechat-article-for-ai.git
cd wechat-article-for-ai
pip install -r requirements.txt

Camoufox browser will be auto-downloaded on first run.

Usage

CLI — Single Article

python main.py "https://mp.weixin.qq.com/s/ARTICLE_ID"

CLI — Batch from File

python main.py -f urls.txt -o ./output -v

CLI Options

Flag Description
urls One or more WeChat article URLs
-f, --file FILE Text file with URLs (one per line, # for comments)
-o, --output DIR Output directory (default: ./output)
-c, --concurrency N Max concurrent image downloads (default: 5)
--no-images Skip image download, keep remote URLs
--no-headless Show browser window (for solving CAPTCHAs)
--force Overwrite existing output
--no-frontmatter Use blockquote metadata instead of YAML frontmatter
-v, --verbose Enable debug logging

MCP Server

Run as an MCP server for AI tool integration:

python mcp_server.py

Tools exposed:

  • convert_article — Convert a single WeChat article to Markdown
  • batch_convert — Convert multiple articles in one call

MCP client configuration (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "wechat-to-md": {
      "command": "python",
      "args": ["mcp_server.py"],
      "cwd": "/path/to/wechat-article-for-ai"
    }
  }
}

Output Structure

output/
  <article-title>/
    <article-title>.md
    images/
      img_001.png
      img_002.jpg
      ...

  converter.py       # markdownify + YAML frontmatter + image URL replacement
  downloader.py      # httpx async + retry per image + Content-Type inference
  cli.py             # argparse CLI with batch support
  mcp_server.py      # FastMCP server with convert_article / batch_convert
main.py              # CLI entry point
mcp_server.py        # MCP server entry point
SKILL.md             # AI skill definition

Troubleshooting

Problem Solution
CAPTCHA / verification page Run with --no-headless to solve manually
Empty content WeChat may be rate-limiting; wait and retry
Image download failures Failed images keep remote URLs; re-run with --force

中文

一个模块化的 Python 工具,将微信公众号文章转换为干净的 Markdown 文件并下载图片到本地。同时支持人工使用(CLI)和 AI 智能体集成(MCP 服务器 + SKILL.md)。

功能特点

  • 反检测抓取 — 使用 Camoufox(隐身 Firefox)绕过微信的反爬机制
  • 智能页面等待 — 使用 networkidle 替代硬编码的 sleep
  • 重试机制 — 页面加载 3 次指数退避重试,图片下载 3 次线性退避重试
  • 验证码检测 — 明确识别验证码页面并给出可操作的错误提示
  • 批量处理 — 支持多个 URL 参数或从文件读取
  • 图片本地化 — 异步并发下载,基于 Content-Type 推断图片格式
  • 代码块保留 — 自动检测编程语言,过滤 CSS 计数器垃圾文本
  • 媒体提取 — 处理微信的 <mpvoice> 音频和 <mpvideo> 视频元素
  • YAML 元数据 — 结构化的 frontmatter(标题、作者、日期、来源)
  • MCP 服务器 — 暴露为工具,供任何 MCP 兼容的 AI 客户端调用
  • SKILL.md — 可直接作为 Claude Code 技能使用

安装

git clone https://github.com/bzd6661/wechat-article-for-ai.git
cd wechat-article-for-ai
pip install -r requirements.txt

Camoufox 浏览器会在首次运行时自动下载。

使用方法

CLI — 单篇文章

python main.py "https://mp.weixin.qq.com/s/文章ID"

CLI — 批量转换

python main.py -f urls.txt -o ./output -v

CLI 参数

参数 说明
urls 一个或多个微信文章链接
-f, --file 文件 包含 URL 的文本文件(每行一个,# 为注释)
-o, --output 目录 输出目录(默认:./output
-c, --concurrency N 图片下载最大并发数(默认:5)
--no-images 跳过图片下载,保留远程链接
--no-headless 显示浏览器窗口(用于手动解决验证码)
--force 覆盖已有的输出目录
--no-frontmatter 使用引用块格式的元数据,而非 YAML frontmatter
-v, --verbose 启用调试日志

MCP 服务器

作为 MCP 服务器运行,供 AI 工具集成:

python mcp_server.py

暴露的工具:

  • convert_article — 转换单篇微信文章为 Markdown
  • batch_convert — 批量转换多篇文章

MCP 客户端配置(如 claude_desktop_config.json):

{
  "mcpServers": {
    "wechat-to-md": {
      "command": "python",
      "args": ["mcp_server.py"],
      "cwd": "/path/to/wechat-article-for-ai"
    }
  }
}

常见问题

问题 解决方法
出现验证码 / 环境异常 使用 --no-headless 手动解决验证码
内容为空 微信可能在限流,等几分钟再试
