notebooklm-mcp-cli-path-env-var-configures-auth-dir
The NOTEBOOKLM_MCP_CLI_PATH environment variable sets the base config directory for upstream notebooklm-mcp-cli’s auth storage. Setting it to a bind-mounted path (e.g., /config mapped to /opt/shared/notebooklm-config/) allows persistent auth across container rebuilds without baking credentials into the image.
