NotebookLM

NotebookLM = external RAG engine that offloads reading from your context window. Uses the notebooklm-mcp-cli MCP server (PyPI, v0.6.1+) to create notebooks, manage sources, generate content, label sources thematically, and query with grounded AI responses. Supports batch operations across notebooks, pipelines, and multilingual content generation.

Disclaimer: Uses internal undocumented Google APIs via browser authentication. Sessions last ~20 minutes. API may change without notice.

What's New (April 2026 — v0.6.1)

• Source labels (NEW in v0.6.0) — Organize sources into thematic categories. New label MCP tool + nlm label CLI: auto (AI generates from sources, requires 5+), list, create, rename, delete, assign, unassign. Surfaces in NotebookLM web UI's source filter.
• Label reorganize (NEW in v0.6.1) — nlm label reorganize (or label MCP with action="reorganize") forces AI re-categorization when labels already exist. Two modes: all-sources (replace, requires --confirm) or unlabeled-only (preserve existing).
• Video formats — 3 formats (explainer, brief, cinematic) + 9 visual styles
• Audio length — audio_length param: short, default, long
• PPTX export — download_artifact(slide_deck_format="pptx") alongside PDF
• Bulk source ops — source_add(urls=[...]), source_delete(source_ids=[...]), source_add(wait=True)
• Studio artifact rename — studio_status(action="rename", artifact_id="...", new_title="...")
• Slide/report/quiz params — slide_format, report_format, difficulty + question_count
• Infographic options — orientation, detail_level, 11 infographic_style options
• Audio sources — Upload m4a, wav, mp3, aac, ogg, opus
• Async large queries — notebook_query_start/notebook_query_status for 50+ source notebooks
• Multi-browser auth — Arc, Brave, Edge, Chromium, Vivaldi, Opera + WSL2 (nlm login --wsl)
• Enterprise — NOTEBOOKLM_BASE_URL env var for Google Workspace deployments
• Security — Download path traversal protection, 0o600 auth files, Chrome origins locked to localhost

Prerequisites

1. Install: uv tool install notebooklm-mcp-cli (or pip install notebooklm-mcp-cli)
2. Authenticate: nlm login (opens browser, session ~20 min)
3. Configure MCP: nlm setup add claude-code (auto-configures .mcp.json) or nlm setup add all for multi-tool setup
4. Verify: nlm login --check to confirm active session
5. Upgrade: uv tool upgrade notebooklm-mcp-cli — restart MCP server after upgrade

CRITICAL: Task Management is MANDATORY (CC 2.1.16)

BEFORE doing ANYTHING else, create tasks to track progress:

# 1. Create main task IMMEDIATELY
TaskCreate(
  subject="NotebookLM: {operation}",
  description="Managing notebooks, sources, and content generation",
  activeForm="Managing NotebookLM resources"
)

# 2. Create subtasks for the notebook workflow
TaskCreate(subject="Notebook setup", activeForm="Creating/configuring notebook")
TaskCreate(subject="Source management", activeForm="Adding sources to notebook")
TaskCreate(subject="Content generation", activeForm="Generating studio content")

# 3. Set dependencies for sequential steps
TaskUpdate(taskId="3", addBlockedBy=["2"])
TaskUpdate(taskId="4", addBlockedBy=["3"])

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done

Key Decisions

Decision	Recommendation
New notebook vs existing	One notebook per project/topic; add sources to existing
Source type	URL for web, text for inline, file for local docs, drive for Google Docs
Large sources	Split >50K chars into multiple sources for better retrieval
Auth expired?	nlm login --check; sessions last ~20 min, re-auth with nlm login
Studio content	Use studio_create, poll with studio_status (generation takes 2-5 min)
Cinematic video	studio_create(artifact_type="video", video_format="cinematic") — requires Plus/Ultra, English only, 20/day
Audio format	Choose brief/critique/debate/deep_dive via audio_format + short/default/long via audio_length
Research discovery	research_start for web/Drive discovery, then research_import (timeout=300s default)
Deep research	research_start(mode="deep") for multi-source synthesis (v0.5.1+, auto-retries)
Release notebooks	One notebook per minor version; upload CHANGELOG + key skill diffs as sources
Query vs search	notebook_query for AI-grounded answers; source_get_content for raw text
Notes vs sources	Notes for your insights/annotations; sources for external documents
Infographic style	11 visual styles via infographic_style param on studio_create
Slide revision	Use studio_revise to edit individual slides (creates a new deck)
Export artifacts	export_artifact sends reports → Google Docs, data tables → Sheets
Language	language param on studio_create accepts BCP-47 codes (e.g., he for Hebrew, en, es, ja)
Bulk source add	source_add(urls=["url1","url2"], wait=True) for multi-URL ingestion with processing wait
Batch operations	Use batch for multi-notebook ops; cross_notebook_query for aggregated answers
Pipelines	pipeline(action="run", pipeline_name="ingest-and-podcast") for multi-step workflows

Example

# 1. Create a notebook for your project
notebook_create(title="Auth Refactor Research")

# 2. Add sources (docs, articles, existing code analysis)
source_add(notebook_id="...", type="url", url="https://oauth.net/2.1/")
source_add(notebook_id="...", type="text", content="Our current auth uses...")
source_add(notebook_id="...", type="file", path="/docs/auth-design.md")

# 3. Query with grounded AI responses
notebook_query(notebook_id="...", query="What are the key differences between OAuth 2.0 and 2.1?")

# 4. Generate a deep dive audio overview (supports language param)
studio_create(notebook_id="...", artifact_type="audio", audio_format="deep_dive", language="he", confirm=True)
studio_status(notebook_id="...")  # Poll until complete

# 5. Generate a cinematic video overview (Plus/Ultra, English)
studio_create(notebook_id="...", artifact_type="video", video_format="cinematic", visual_style="classic", confirm=True)
studio_status(notebook_id="...")  # Poll — takes 3-8 minutes

# 6. Capture insights as notes
note(notebook_id="...", action="create", content="Key takeaway: PKCE is mandatory in 2.1")

Common Mistakes

• Forgetting auth expiry — Sessions last ~20 min. Always check with nlm login --check before long workflows. Re-auth with nlm login.
• One giant notebook — Split by project/topic. One notebook with 50 sources degrades retrieval quality.
• Huge single sources — Split documents >50K characters into logical sections for better chunking and retrieval.
• Not polling studio_status — Studio content generation takes 2-5 minutes. Poll studio_status instead of assuming instant results.
• Ignoring source types — Use type=url for web pages (auto-extracts), type=file for local files. Using type=text for a URL gives you the URL string, not the page content.
• Deleting notebooks without checking — notebook_delete is irreversible. List contents with source_list_drive and note(action=list) first.
• Skipping research_import — research_start discovers content but does not add it. Use research_import to actually add findings as sources.
• Raw queries on empty notebooks — notebook_query returns poor results with no sources. Add sources before querying.
• Ignoring language param — studio_create supports BCP-47 language codes (e.g., he, ar, ja). Defaults to English if omitted.
• Batch without purpose — batch and cross_notebook_query are powerful but add latency. Use for multi-project synthesis, not single-notebook tasks.
