notebooklm-mcp-upstream-profile-dir-two-file-auth-format
The upstream notebooklm-mcp-cli expects TWO files under $NOTEBOOKLM_MCP_CLI_PATH/profiles/default/: cookies.json (the cookie payload) and metadata.json (profile metadata). The env var NOTEBOOKLM_MCP_CLI_PATH must point to the directory that contains the profiles/ subdirectory — not directly to the profile. CSRF tokens and session IDs are auto-extracted by the upstream on first API call; only cookies are needed in cookies.json.
