notebooklm-mcp

An MCP server that lets Claude (or any MCP client) use Google NotebookLM, now also called Gemini Notebook, with a free Google account.

It drives the real NotebookLM website in its own Chrome window. The tools find buttons, links and text boxes by their accessible role and name (what a screen reader sees), not by CSS selectors. The agent reads the page fresh before each step, so it keeps working when Google changes the layout.

Unofficial. This is not affiliated with Google. It automates the normal website, which may go against Google's Terms of Service and may stop working if Google blocks automated browsers. Use it for personal and experimental work, at your own risk.

Tools

Shortcuts for common jobs (they fall back to the general tools if the site changes too much):

Tool

What it does

nlm_list_notebooks

List your notebooks with their URLs

nlm_create_notebook

Create a notebook, optionally with a title

nlm_ask

Ask a notebook (by title, id or URL) a question and return the finished answer

nlm_add_source

Add website/YouTube URLs, pasted text and/or local files as sources

nlm_download

Click a download button or menu item and save the file (default ~/Downloads/NotebookLM)

General tools, which work on any page:

Tool

What it does

nlm_snapshot

Accessibility tree of the page: every element's role, name and text

nlm_open

Go to a URL (default: NotebookLM home, which lists your notebooks)

nlm_click

Click an element by role/name, or by visible text

nlm_type

Fill a text field and optionally press Enter

nlm_press

Press a key, e.g. Escape to close a popup

nlm_upload

Click an upload button and give it local files

nlm_read

Read the visible text of the page or one element (e.g. a full answer)

nlm_wait

Wait for an answer or source to finish, or until some text appears

nlm_screenshot

PNG of the page when the text view is not enough

With these the agent can list, open, create and search notebooks, add sources, ask questions with citations, and make Studio content (Audio Overviews, slides, mind maps, quizzes, reports, ...).

Setup

Needs Node.js 18+ and a Chrome-type browser. It uses, in order: NLM_CHROME, an installed Google Chrome or Chromium, or a Chromium downloaded by Playwright (npx playwright install chromium).

The commands below use the npm package notebooklm-browser-mcp. You can also run it straight from GitHub by writing github:DwytMCL/notebooklm-mcp in its place.

Sign in to Google once. This opens a separate Chrome window with its own profile:

npx -y notebooklm-browser-mcp login

Sign in, check your notebooks load, then quit that window (Cmd+Q / close all windows). The server cannot attach while the sign-in window is still open.

Sign in separately for each tool. Never copy a signed-in profile folder to another browser or server: Google sees the same session in two browsers, revokes it, and both come back signed out after the next restart.

Claude Code

claude mcp add -s user notebooklm -- npx -y notebooklm-browser-mcp

Claude Desktop

Add to claude_desktop_config.json and restart Claude Desktop:

{
  "mcpServers": {
    "notebooklm": {
      "command": "npx",
      "args": ["-y", "notebooklm-browser-mcp"]
    }
  }
}

From source

git clone https://github.com/DwytMCL/notebooklm-mcp.git
cd notebooklm-mcp
npm install
node server.js login
npm test   # starts the server, lists the tools and opens NotebookLM

Then use node /absolute/path/to/notebooklm-mcp/server.js as the command instead of npx.

Settings

All optional, set as environment variables:

Variable

Default

Meaning

NLM_CHROME

Google Chrome, else Playwright's Chromium

Path to the Chrome/Chromium binary

NLM_PROFILE

~/.notebooklm-mcp/profile

Browser profile holding your Google sign-in

NLM_PORT

9333

Local port the server uses to control Chrome

NLM_DOWNLOADS

~/Downloads/NotebookLM

Where nlm_download saves files

Privacy

Your Google session lives only in the browser profile folder on your machine (NLM_PROFILE). Nothing is sent anywhere except to Google by the browser itself. Treat that folder like a password: don't share or commit it. Chrome's control port listens on 127.0.0.1 only, but any program on your machine could use it while the window is open.
