notebooklm-mcp-cli-auth-two-file-format
Upstream notebooklm-mcp-cli stores auth in TWO files under $NOTEBOOKLM_MCP_CLI_PATH/profiles/default/: cookies.json (cookie key-value pairs) AND metadata.json (session metadata). The single-file storage_state.json from notebooklm-py does not map 1:1. CSRF token and session ID are auto-extracted by upstream on first API call — only the cookies file is strictly required for initial setup.
