What is notebooklm-mcp-fork GEMINI.md?

A set of setup instructions for using the NotebookLM MCP server and command-line tool with Gemini CLI. NotebookLM is Google's notebook-based research assistant, and MCP is a way for software tools to expose functions to AI agents.

Use it when installing the project, configuring its environment, authenticating through Chrome, or understanding its repository and setup requirements.

It explains the required Python, package-manager, browser, installation, and login steps needed to use the project. It also documents that the project relies on internal Google interfaces and may not work for every account type.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01485	$0.01485
Opus 5	$0.00743	$0.00743

Security

Grade A, and why

notebooklm-mcp-fork GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to gemini-notebook-mcp-cli GEMINI.md — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Project Overview

NotebookLM MCP Server & CLI

This project implements a Model Context Protocol (MCP) server and a full-featured Command Line Interface (CLI) that provides programmatic access to NotebookLM. It allows AI agents, developers, and power users to interact with NotebookLM notebooks, sources, query capabilities, and download generated artifacts (Audio, Video, PDF, etc.).

Tested with personal/free tier accounts. May work with Google Workspace accounts but has not been tested. This project relies on internal APIs (batchexecute RPCs).

Environment & Setup

The project uses uv for dependency management and tool installation.

Prerequisites

Python 3.11+
uv (Universal Python Package Manager)
Google Chrome (for automated authentication)

Installation

From PyPI (Recommended):

uv tool install notebooklm-mcp-cli
# or: pip install notebooklm-mcp-cli

From Source (Development):

git clone https://github.com/YOUR_USERNAME/notebooklm-mcp.git
cd notebooklm-mcp
uv tool install .

Authentication

Preferred: Run the automated authentication CLI:

nlm login

This launches Chrome, you log in, and cookies are extracted automatically. Your login is saved to a Chrome profile for future use.

Auto-refresh (v0.1.9+): The server now automatically handles token expiration:

Refreshes CSRF tokens on expiry (immediate)
Reloads cookies from disk if updated externally
Runs headless Chrome auth if profile has saved login

If headless auth fails (Google login fully expired), you'll see a message to run nlm login again.

Explicit refresh (MCP tool):

refresh_auth()  # Reload tokens from disk or run headless auth

Fallback: Manual extraction (if CLI fails) If the automated tool doesn't work, extract cookies via Chrome DevTools:

Open Chrome DevTools on notebooklm.google.com
Go to Network tab, find a batchexecute request
Copy the Cookie header and call save_auth_tokens(cookies=...)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
