API for downloading subtitles from YouTube videos
API for downloading subtitles from YouTube videos
An MCP server (stdio; remote HTTP/SSE via mcp-proxy) that fetches video transcripts/subtitles via yt-dlp, with pagination for large responses. Supports YouTube, Twitter/X, Instagram, TikTok, Twitch, Vimeo, Facebook, Bilibili, VK, Dailymotion, Reddit. Whisper fallback — transcribes audio when subtitles are unavailable (local or OpenAI API). Works with Cursor and other MCP hosts.
This repository primarily ships a stdio MCP server (node dist/mcp.js):
