安裝
uv venv
source .venv/bin/activate
uv pip install "mcp[cli]" httpx python-dotenv設定金鑰(擇一)
A. 用 .env(推薦)
在專案根目錄建立 .env:
YOUTUBE_API_KEY=YOUR_API_KEY_HEREB. 寫在客戶端設定的 env(見下方範例)
在 Claude Desktop 使用(本機 STDIO)
開啟:Settings → Developer → Local MCP servers → Edit Config
加入(請把絕對路徑換成你的實際路徑):
{
"mcpServers": {
"yt_comments": {
"command": "<abs path>/yt_mcp/.venv/bin/python",
"args": ["<abs path>/yt_mcp/server.py"],
"env": { "YOUTUBE_API_KEY": "YOUR_API_KEY" } // 若已用 .env,可移除此段
}
}
}也可不填
env,改用專案根目錄的.env。
回到 Local MCP servers 啟動
yt_comments。新開對話請 Claude 呼叫:
yt_comments.fetch_comments(
videoUrl="https://www.youtube.com/watch?v=XXXXXXXXXXX",
order="relevance",
max=300
)接著請模型做摘要/分類/翻譯並輸出報告。

}
]
}Troubleshooting
Missing YOUTUBE_API_KEY 在
.env或設定的env補上金鑰,並確認金鑰已啟用 YouTube Data API v3。找不到
server.py在設定裡把args改用絕對路徑(例如"/Users/you/yt_mcp/server.py")。ModuleNotFoundError 確認已在虛擬環境內安裝相依套件(
"mcp[cli]" httpx python-dotenv)。HTTP 403/400 可能是配額不足、影片關閉留言、或金鑰權限未開。
安全
.env已在.gitignore中,請勿提交金鑰。若曾不小心提交金鑰,請 旋轉金鑰 並清理 Git 歷史。
