check_auth
Verify stored credentials are valid
How to use it
Project documentation lists check_auth for the Notebooklm MCP 2026 MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
