social-mcp

用 CDP Browser Hijacking 操作主流社交平台——不需要 API Token,不需要開發者帳號。

透過你自己瀏覽器的登入 session,AI Agent 用 CDP 接管來發文、爬蟲、對話。

2026-04-25 實測成果

平台 功能 狀態
X.com 搜索熱門話題、爬蟲 ✅ 實測成功
Gemini AI 對話(分析項目、生成內容) ✅ 實測成功
Facebook 發布文字/圖片帖、讀私訊、讀通知 ✅ 實測成功
Threads 發布文字/圖片帖 ✅ 實測成功
Instagram 發布圖片帖 ✅ 實測成功

Status Platform

原理

你親自登入一次(Chromium — FacebookMCP profile)
         ↓
Chromium 啟動 --remote-debugging-port=9333
         ↓
Playwright CDP 接管瀏覽器
         ↓
直接操作 DOM(發文 / 爬蟲 / 對話)

為什麼不走官方 API?

  • Facebook Graph API 只能操作粉絲專頁,個人帳號的私訊/通知讀不到
  • X API 要付費才能發文
  • 我們的方案:你的帳號能做什麼,AI 就能做什麼

為什麼不直接 launch Playwright?

  • macOS Chrome cookies 用 login.keychain 加密,外部程序無法解密
  • 透過 CDP 接管一個已解密 session,繞過這個限制

安裝

git clone https://github.com/whypuss/social-mcp.git
cd social-mcp
uv sync

設定

1. 建立獨立 Chromium profile

mkdir -p ~/Library/Application\ Support/Chromium/FacebookMCP

2. 登入各平台

open -a Chromium --args --user-data-dir="$HOME/Library/Application Support/Chromium/FacebookMCP"

在瀏覽器中分別登入:

  • Facebook(只需一次)
  • Instagram(只需一次)
  • Threads(Facebook 登入後同步)
  • Google(Gemini 用,選擇性)
  • X.com 不需要登入

3. 啟動 CDP Server

"/Applications/Chromium.app/Contents/MacOS/Chromium" \
  --remote-debugging-port=9333 \
  --user-data-dir="$HOME/Library/Application Support/Chromium/FacebookMCP" \
  --profile-directory="Default" &

4. 支援多個 CDP 端口

browser_hijack.py 會自動檢測 93339222,哪個有活躍 session 就用哪個。

使用範例

直接發文測試

# Facebook 文字帖
uv run python -m social_mcp.post_facebook "測試訊息 🚀"

# Facebook 圖文帖
uv run python -m social_mcp.post_facebook "測試訊息" /tmp/image.jpg

# Threads 圖文帖
uv run python scripts/post_threads "測試訊息 🚀" --image /tmp/image.jpg

# Instagram 圖文帖
uv run python scripts/post_instagram "caption text" /tmp/image.jpg

AI 對話(Gemini)

用 CDP 接管 Gemini 網頁,直接對話:

# 在 Gemini 頁面輸入 prompt,自動分析 GitHub 項目
prompt = "請分析 https://github.com/whypuss/social-mcp"
# → Gemini 回傳完整分析報告

X.com 爬蟲

# 爬取熱門話題(20ms 拿到數據)
await page.goto("https://x.com/explore/tabs/trending")
trending = await page.evaluate("""
    () => {
        const cells = document.querySelectorAll("[data-testid='cellInnerDiv']");
        return Array.from(cells).map(c => c.innerText).filter(t => t.length > 20);
    }
""")
# → ["#TermMaxPuzzleChallenge", "#SECAwards", ...]

架構

social_mcp/
├── browser_hijack.py    # CDP 接管核心(多端口自動檢測)
├── mcp_server.py       # MCP Server(Hermes Agent / Claude Desktop)
├── post_facebook.py    # Facebook 發文(支援圖片)
├── post_threads.py     # Threads 發文(支援圖片)
├── post_instagram.py   # Instagram 發文(支援圖片)
└── scripts/
    └── post_instagram.py  # Instagram 獨立腳本

全新電腦復現

只需三樣東西:

項目 備份/復現
Chromium.app brew install --cask chromium
FacebookMCP profile ~/Library/Application Support/Chromium/FacebookMCP/(拷貝)
social-mcp 環境 git clone + uv sync

拷貝 FacebookMCP profile 後,所有平台(Facebook / IG / Threads / Google)全部復現,不需要重新登入

常見問題

Q: session 會過期嗎? A: Facebook 有時會要求重新驗證。操作失敗時,在 CDP Chromium 視窗重新登入一次即可。

Q: 支援粉絲專頁嗎? A: 目前支援個人帳號。粉絲專頁需切換身份,DOM selector 需要調整。

Q: X.com 需要登入嗎? A: 不需要。X.com 的內容可以匿名瀏覽。

Q: Gemini 生成圖片可以嗎? A: 免費版不行,需要升級 Google AI Plus。文字對話和項目分析都正常。

安全性

  • Cookies 永遠留在本地,不會傳到第三方
  • 不使用任何官方 API,不需要 access token
  • 獨立 profile,不影響日常瀏覽 session

警告:大量自動化操作可能違反各平台服務條款,請自行評估風險。
