Official NotebookLM MCP Server

**Description**
I would like to suggest the development of an **official** Model Context Protocol (MCP) server for NotebookLM. While the community has created excellent implementations (e.g., `PleasePrompto/notebooklm-mcp` or `jacob-bd/notebooklm-mcp-cli`), an official version from Google would provide the stability and security required for professional workflows.

**Suggested Capabilities**
To provide a superior experience compared to existing community tools, an official server could consider:

* **Native Authentication:** Moving away from browser automation/cookie extraction toward official OAuth integration.
* **Source & Studio Management:** Tools not only to query notebooks but also to sync Drive/Web sources and trigger the creation of "Audio Overviews" or study guides.
* **Context Discovery:** A tool to search the user's library and auto-select the most relevant notebook for a specific task.
* **Grounded Querying:** Leveraging Gemini’s synthesis to provide citation-backed answers directly to MCP-compatible hosts (Claude, Cursor, etc.).

I've been looking at community versions like jacob-bd's or PleasePrompto's, and the interest is clearly there.
