## Tools
> **NotebookLM MCP Structured v1.0.0** - Tools with automatic prompt structuring and source fidelity.
### Core Tools (with Auto-Auth)
Tools marked with 🔐 automatically verify authentication and trigger login if needed.
- `ask_question` 🔐
- **Key Feature**: Automatically structures your question for source fidelity
- Parameters: `question` (string, required), optional `session_id`, `notebook_id`, `notebook_url`, `show_browser`
- **Structuring includes**:
- Source constraints (ONLY from uploaded documents)
- Citation requirements (source attribution for every claim)
- Missing info handling (`[NOT FOUND IN DOCUMENTS]`)
- Question type detection (comparison, list, analysis, explanation, extraction)
- Returns NotebookLM's source-faithful answer plus follow-up reminder
- ⚠️ Never include decorative lines (`===` or `---`) - causes timeouts
- `reset_session` 🔐
- Reset a session to start fresh
- Triggers auto-auth if needed
- `list_sessions`, `close_session`
- Inspect or manage active browser sessions (no auth required)
### Authentication & Diagnostics
- `get_health`
- **Enhanced diagnostics**: Auth status, Chrome state, connection verification
- Shows if Chrome is running (blocks auth setup)
- Reports active sessions and configuration
- `setup_auth`
- Opens persistent Chrome profile for Google login
- ⚠️ Requires Chrome to be closed first
- `re_auth`
- Switch to a different Google account or re-authenticate
- Use when NotebookLM rate limit is reached (50 queries/day for free accounts)
- Closes all sessions, clears auth data, opens browser for fresh login
### Notebook library
- `add_notebook` – Safe conversational add; expects confirmation before writing.
- `list_notebooks` – Returns id, name, topics, URL, metadata for every entry.
- `get_notebook` – Fetch a single notebook by id.
- `select_notebook` – Set the active default notebook.
- `update_notebook` – Modify metadata fields.
- `remove_notebook` – Removes entries from the library (not the original NotebookLM notebook).
- `search_notebooks` – Simple query across name/description/topics/tags.
- `get_library_stats` – Aggregate statistics (total notebooks, usage counts, etc.).
### Resources
- `notebooklm://library`
- JSON representation of the full library: active notebook, stats, individual notebooks.
- `notebooklm://library/{id}`
- Fetch metadata for a specific notebook. The `{id}` completion pulls from the library automatically.
**Remember:** Every `ask_question` response ends with a reminder that nudges your agent to keep asking until the user’s task is fully addressed.
