Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

Continue usa un array de objetos de servidor en lugar de un mapa.

Herramientas

Lo que expone este MCP

Herramienta	Entradas	Cuándo llamar	Coste
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

Coste y límites

Lo que cuesta ejecutarlo

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

Seguridad

Permisos, secretos, alcance

Almacenamiento de credenciales: Proxy credentials if you use Webshare — env var

Salida de datos: 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.

Resolución de problemas

Errores comunes y soluciones

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 otros

Alternativa	Cuándo usarla	Contrapartida
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
