~/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
    }
  }
}

Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

VS Code → Cline → MCP Servers → Edit

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

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Mesmo formato do Claude Desktop. Reinicie o Windsurf para aplicar.

~/.continue/config.json

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

O Continue usa um array de objetos de servidor em vez de um map.

          "mcp-youtube-transcript"
        ]
      }
    }
  }
}

Adicione em context_servers. Zed recarrega automaticamente ao salvar.

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
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

Custo e limites

O que custa rodar

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

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: Proxy credentials if you use Webshare — env var

Saída de dados: 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.

Solução de problemas

Erros comuns e correções

HTTP 429 Too Many Requests

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

Verificar: 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+.

Verificar: uv --version

Alternativas

mcp-youtube-transcript vs. outros

Alternativa	Quando usar	Troca
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
