SubDownload MCP Server
SubDownload exposes YouTube as an MCP-native data source. Connect once via OAuth and your AI agent gets tools to summarize videos, fetch full transcripts (including videos without captions, via AI ASR), search channels and playlists, and save everything into a per-user knowledge base for cross-session recall.

The recommended setup is to point your MCP client directly at the hosted endpoint above and authenticate via OAuth — see "Quick connect" below. This repo also ships a thin stdio proxy (Node + Docker) for environments that prefer a local subprocess.
Auth
OAuth 2.1 with Dynamic Client Registration (RFC 7591). No pre-shared client_id or client_secret — your MCP client registers itself on first connect.
