Setup
Install SubDownload in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/subdownload/subdownload-mcp
Follow the installation instructions in the repository README, then restart your MCP client.
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.
- Hosted endpoint:https://api.subdownload.com/mcp

- Glama (server):https://glama.ai/mcp/servers/SubDownload/subdownload-mcp
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.
OAuth 2.1 with Dynamic Client Registration (RFC 7591). No pre-sharedclient_idorclient_secret— your MCP client registers itself on first connect.
- POST to/mcpwithout a token returns401plus aWWW-Authenticateheader pointing to/.well-known/oauth-protected-resource
- That document points to the authorization server (https://api.subdownload.com)
- The MCP client follows the standard authorize → callback → token flow with PKCE
API-key alternative: every account athttps://subdownload.com/accountexposes a Bearer token for clients that don't support OAuth.
