mcp-server-youtube

mcp-server-youtube

A Rust MCP server for YouTube. Search videos, read channels, browse playlists, fetch comments, and get transcripts — all from your AI assistant.

Why this one?

• Full YouTube Data API v3 coverage — videos, channels, playlists, comments, categories, trending, search with all filters and sorting options
• Working transcripts — uses rustypipe (InnerTube API) for reliable subtitle/caption extraction, including auto-generated captions. No API key quota consumed for transcripts
• Single binary, zero runtime dependencies — written in Rust, starts instantly
• Typed filter enums — search filters (duration, definition, license, etc.) are exposed as typed enums in the JSON schema, so AI models know exactly which values are valid without guessing
