NotebookLM MCP Server

Overview

NotebookLM MCP Server lets MCP clients use Google NotebookLM through browser automation. It drives Chrome or bundled Patchright Chromium to authenticate with a Google account, query NotebookLM notebooks with Gemini 2.5 grounded on user-uploaded sources, ingest URL or text sources, manage a local notebook library, handle multi-turn sessions, extract citations, and generate/download Audio Overviews.

Install

Recommended package launch:

npx notebooklm-mcp@latest

Local source workflow:

git clone https://github.com/PleasePrompto/notebooklm-mcp
cd notebooklm-mcp
npm install
npm run build
node dist/index.js

Transports

The default transport is stdio, using command npx and args ["notebooklm-mcp@latest"], matching the importer output. The server can also run Streamable HTTP with --transport http --port 3000; bind with --host 0.0.0.0 only on trusted networks. HTTP routes are POST /mcp, GET /mcp, DELETE /mcp, and GET /healthz; the MCP SDK session lifecycle uses the Mcp-Session-Id header after initialization.

Authentication

First-time setup uses the setup_auth tool, which opens a visible Chrome window for Google login and persists cookies in a per-user Chrome profile. re_auth clears auth and starts over. cleanup_data previews and deletes stored browser state, logs, and profiles, with preserve_library=true available for auth repair. Optional scripted login exists through AUTO_LOGIN_ENABLED, LOGIN_EMAIL, and LOGIN_PASSWORD, but secret and user-specific values are left empty in the package config.

Capabilities

Tools reviewed include ask_question, add_source, generate_audio, get_audio_status, download_audio, add_notebook, list_notebooks, get_notebook, select_notebook, update_notebook, remove_notebook, search_notebooks, get_library_stats, list_sessions, close_session, reset_session, get_health, setup_auth, re_auth, and cleanup_data. Read-only resources reviewed are notebooklm://library, notebooklm://library/{id}, and deprecated notebooklm://metadata. Tool profiles can reduce exposed tools: minimal, standard, or full (default).

Limitations

The server depends on Google NotebookLM UI behavior and a launchable Chrome/Chromium browser. WSL1 is not supported; WSL2 with WSLg is supported. Headless servers still need a display for one-time setup_auth, commonly via xvfb-run. File, YouTube, and Google Drive source uploads are not implemented in v2.0.0; add_source supports URL and text. Audio Overview is the only wrapped Studio output. Free NotebookLM accounts can hit daily query limits. Multi-account isolation is by Chrome profile directory, not an encrypted credential store.
