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):

General tools, which work on any page:

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:

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.
