This tool operates as an MCP server, providing robust capabilities for fetching YouTube video transcripts. It can extract transcripts from various YouTube URL formats or direct video IDs, supporting both human-generated and automatically produced captions. Security is paramount, with Google OAuth 2.0 authentication ensuring that only pre-authorized users can access transcript data based on their email addresses. The server also handles pagination for very long transcripts and allows users to list all available transcript options for a given video, making it ideal for integration into applications requiring structured access to YouTube video dialogue.
