安裝

選擇你的客戶端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "mcp-youtube-transcript"
      ],
      "_inferred": true
    }
  }
}

開啟 Claude Desktop → Settings → Developer → Edit Config。儲存後重啟應用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "mcp-youtube-transcript"
      ],
      "_inferred": true
    }
  }
}

Cursor 使用與 Claude Desktop 相同的 mcpServers 格式。專案級設定優先於全域。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "mcp-youtube-transcript"
      ],
      "_inferred": true
    }
  }
}

點擊 Cline 側欄中的 MCP Servers 圖示，然後選 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "mcp-youtube-transcript"
      ],
      "_inferred": true
    }
  }
}

格式與 Claude Desktop 相同。重啟 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "youtube-transcript",
      "command": "uvx",
      "args": [
        "mcp-youtube-transcript"
      ]
    }
  ]
}

Continue 使用伺服器物件陣列，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "youtube-transcript": {
      "command": {
        "path": "uvx",
        "args": [
          "mcp-youtube-transcript"
        ]
      }
    }
  }
}

加入 context_servers。Zed 儲存後熱重載。

claude mcp add youtube-transcript -- uvx mcp-youtube-transcript

一行命令搞定。用 claude mcp list 驗證，claude mcp remove 移除。

使用場景

實戰用法： mcp-youtube-transcript

Turn a 60-minute YouTube talk into a 10-bullet summary with timestamps

👤 Researchers, content marketers, students ⏱ ~10 min beginner

何時使用： You can't watch the full video but need the key points (and to cite them with timestamps).

步驟

Fetch timed transcript

Get timed transcript for https://www.youtube.com/watch?v=VIDEO_ID.✓ 已複製

→ Transcript with [MM:SS] markers
Summarize with citations

Give me 10 bullets summarizing the main argument. Each bullet should end with a [MM:SS] pointer to where it's made in the video.✓ 已複製

→ Bulleted summary with clickable-style timestamps

結果： Digestible summary you can share with a team Slack in 2 minutes.

注意事項

Auto-generated captions have errors on technical terms — For accuracy-critical quotes, verify against the actual video at the timestamp

搭配使用： notion

Index a YouTube podcast's back catalog for semantic search

👤 Podcast fans, researchers following a specific show ⏱ ~45 min intermediate

何時使用： You want to ask 'which episode did they talk about X?' across 100+ episodes.

步驟

List episode URLs

Here's the playlist URL. Get the 50 most recent video IDs.✓ 已複製

→ Video ID list
Fetch + index

For each video, get_transcript and get_video_info (title, date). Ingest into local-rag as one doc per episode.✓ 已複製

→ Indexed corpus
Query

In which episodes did the hosts discuss 'ring attention'? Give episode number and timestamp.✓ 已複製

→ Hits with episode metadata

結果： A searchable podcast library you own and control.

注意事項

Some videos have no captions — get_available_languages first; skip if empty

搭配使用： local-rag

Translate a talk from one language to another

👤 Non-English speakers, content localizers ⏱ ~10 min beginner

何時使用： You want to read a Spanish talk in English without running ML translation yourself.

步驟

Grab original language transcript

get_available_languages for this URL. Use Spanish if available.✓ 已複製

→ Spanish transcript
Translate

Translate this transcript to English, preserving paragraph breaks.✓ 已複製

→ English text

結果： Read-worthy translated transcript.

注意事項

Tonal / idiomatic content translates awkwardly — For commercial localization, have a human pass

組合

與其他 MCP 搭配，撬動十倍槓桿

youtube-transcript + local-rag

Ingest a channel's transcripts into a searchable local index

For each video in this playlist, get transcript + metadata, then ingest_data into local-rag with source URL.✓ 已複製

youtube-transcript + notion

Publish video summaries to a Notion knowledge DB

Summarize this talk and create a Notion page in 'Talks' with title, channel, date, and summary.✓ 已複製

工具

此 MCP 暴露的能力

工具	輸入參數	何時呼叫	成本
get_transcript	url_or_id: str, language?: str	You want text only, no timestamps	free
get_timed_transcript	url_or_id, language?	You need timestamps for citations or chapter generation	free
get_video_info	url_or_id	Metadata for context / indexing	free
get_available_languages	url_or_id	Check caption availability before attempting fetch	free

成本與限制

運行它的成本

API 配額: YouTube doesn't officially expose transcripts — expect IP rate limits
每次呼叫 Token 數: Transcripts 1k-50k tokens depending on length; paginated at 50k by default
費用: Free; proxies (Webshare) cost a few $/mo if you need them
提示: Transcripts are often huge. Truncate via --response-limit or just ask for a specific time range.

安全

權限、密鑰、影響範圍

憑證儲存： Proxy credentials if you use Webshare — env var

資料出站： Outbound to youtube.com (possibly via proxy)

YouTube actively blocks scraping. From datacenter IPs expect 429s — use a residential proxy (Webshare) if persistent.
Respect each video's copyright — transcripts are useful for summarization and research, not wholesale reproduction.

故障排查

常見錯誤與修復

HTTP 429 Too Many Requests

Your IP is rate-limited by YouTube. Configure Webshare proxy via env vars or wait 30-60 minutes.

驗證： Try the same URL from another IP

No transcript available

Video has no captions. Call get_available_languages first; if empty, skip.

Age-restricted / region-locked video

Not supported by this MCP. No workaround — use official YouTube Data API with auth.

Python install issues (uvx)

Install uv first: curl -LsSf https://astral.sh/uv/install.sh | sh. Requires Python 3.10+.

驗證： uv --version

替代方案	何時用它替代	權衡
YouTube Data API + official MCP wrapper	You need official, authenticated access	Requires Google API key; quota limits; doesn't directly give transcript text
yt-dlp MCP	You also want video/audio download, not just transcripts	Heavier; downloads media files
