MCP proxy for SubDownload — YouTube knowledge base for AI agents
MCP proxy for SubDownload — YouTube knowledge base for AI agents
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.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
