설치

클라이언트 선택

~/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
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

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

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

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

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

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

context_servers에 추가. 저장 시 Zed가 핫 리로드.

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

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
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

비용 및 제한

운영 비용

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

보안

권한, 시크릿, 파급범위

자격 증명 저장: Proxy credentials if you use Webshare — env var

데이터 외부 송신: 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.

문제 해결

자주 발생하는 오류와 해결

HTTP 429 Too Many Requests

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

확인: 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+.

확인: uv --version

대안

mcp-youtube-transcript 다른 것과 비교

대안	언제 쓰나	단점/장점
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
