💡 Gemini API is completely optional! All core NotebookLM features (ask_question, notebooks, sessions, audio) work via browser automation with no API key required. The Gemini tools below are bonus features for users who want direct API access.

Gemini Configuration (Optional)

# Only required if you want Gemini API features (deep_research, gemini_query, upload_document)
GEMINI_API_KEY=your-api-key          # Get from https://aistudio.google.com/apikey

# Optional settings
GEMINI_DEFAULT_MODEL=gemini-3-flash-preview  # Default model (was gemini-2.5-flash)
GEMINI_DEEP_RESEARCH_ENABLED=true            # Enable Deep Research
GEMINI_TIMEOUT_MS=30000                      # API timeout

When to Use Which

📄 Document API (v1.9.0)

Upload and query documents directly via Gemini API — no browser automation needed.

v1.9.0 introduces the Gemini Files API for fast, reliable document analysis. Upload PDFs, analyze them instantly, and delete when done.

Why This Matters

New Tools

upload_document — Fast Document Upload

Upload any document to Gemini for instant querying:

Upload /path/to/research-paper.pdf

• Supported: PDF (50MB, 1000 pages), TXT, MD, HTML, CSV, JSON, DOCX, images, audio, video
• 48-hour retention — files auto-expire, or delete manually
• Returns a file ID for querying

query_document — Ask Questions About Documents

"What are the main findings in this research paper?"
"Summarize section 3 of the document"
"Extract all statistics mentioned in the PDF"

• Full document understanding (text, tables, charts, diagrams)
• Multi-document queries (compare multiple files)
• Fast API response (no browser wait)

list_documents — See All Uploaded Files

List all my uploaded documents

Shows file names, sizes, MIME types, and expiration times.

delete_document — Clean Up Sensitive Files

Delete file xyz123

Immediately remove files (don't wait for 48h expiration).

Workflow Example

1. upload_document("/research/paper.pdf")
   → Returns: files/abc123

2. query_document("files/abc123", "What methodology was used?")
   → Returns: "The paper uses a mixed-methods approach combining..."

3. query_document("files/abc123", "List all cited authors")
   → Returns: "Smith et al. (2024), Johnson (2023)..."

4. delete_document("files/abc123")
   → File removed

Auto-Chunking for Large PDFs (v1.10.0)

No file size limits — PDFs of any size are automatically handled.

When you upload a PDF that exceeds Gemini's limits (50MB or 1000 pages), the system automatically:

1. Detects the oversized PDF
2. Splits it into optimal chunks (500 pages each)
3. Uploads all chunks in parallel
4. Returns chunk metadata for querying

upload_document("/research/massive-2000-page-report.pdf")

→ Returns:
{
  "wasChunked": true,
  "totalPages": 2000,
  "chunks": [
    { "fileName": "files/abc1", "pageStart": 1, "pageEnd": 500 },
    { "fileName": "files/abc2", "pageStart": 501, "pageEnd": 1000 },
    { "fileName": "files/abc3", "pageStart": 1001, "pageEnd": 1500 },
    { "fileName": "files/abc4", "pageStart": 1501, "pageEnd": 2000 }
  ],
  "allFileNames": ["files/abc1", "files/abc2", "files/abc3", "files/abc4"]
}

query_chunked_document — Query All Chunks at Once

For chunked documents, use this tool to query all parts and get an aggregated answer:

query_chunked_document(
  file_names: ["files/abc1", "files/abc2", "files/abc3", "files/abc4"],
  query: "What are the key recommendations in this report?"
)

→ Queries each chunk, then synthesizes a unified answer

When to Use Document API vs NotebookLM

Programmatic Notebook Creation (v1.7.0+)

Create NotebookLM notebooks entirely from code — no manual clicks required.

Most MCP servers can only read from NotebookLM. This one can create notebooks, add sources, and generate audio — all programmatically.

create_notebook — Build Notebooks Instantly

Create a complete notebook with multiple sources in one command:

{
  "name": "Security Research 2025",
  "sources": [
    { "type": "url", "value": "https://owasp.org/Top10" },
    { "type": "file", "value": "/path/to/security-report.pdf" },
    { "type": "text", "value": "Custom analysis notes...", "title": "My Notes" }
  ],
  "description": "OWASP security best practices",
  "topics": ["security", "owasp", "vulnerabilities"]
}

Supported source types:

• URL — Web pages, documentation, articles
• File — PDF, DOCX, TXT, and more
• Text — Raw text, code snippets, notes

batch_create_notebooks — Scale Up

Create up to 10 notebooks in a single operation:

{
  "notebooks": [
    { "name": "React Docs", "sources": [{ "type": "url", "value": "https://react.dev/reference" }] },
    { "name": "Node.js API", "sources": [{ "type": "url", "value": "https://nodejs.org/api/" }] },
    { "name": "TypeScript Handbook", "sources": [{ "type": "url", "value": "https://www.typescriptlang.org/docs/" }] }
  ]
}

Perfect for:

• Setting up project documentation libraries
• Onboarding new team members with curated knowledge bases
• Creating topic-specific research notebooks in bulk

manage_sources — Dynamic Source Management

Add or remove sources from existing notebooks:

{
  "notebook_id": "abc123",
  "action": "add",
  "sources": [{ "type": "url", "value": "https://new-documentation.com" }]
}

generate_audio — Audio Overview Creation

Generate NotebookLM's famous "Audio Overview" podcasts programmatically:

"Generate an audio overview for my Security Research notebook"

sync_notebook — Keep Sources Updated

Sync notebook sources from a local directory:

{
  "notebook_id": "abc123",
  "directory": "/path/to/docs",
  "patterns": ["*.md", "*.pdf"]
}

Why This Matters

Your agent can now build entire knowledge bases autonomously.

🎬 Video Overviews & Data Tables (v2026.2.0)

Generate AI-powered visual summaries and extract structured data from any notebook — all programmatically.

NotebookLM's Studio panel now offers Video Overviews and Data Tables alongside Audio Overviews. This release brings full automation for both.

generate_video_overview — AI Video Summaries

Generate visual video overviews of your notebook content with 10 visual styles:

Two formats:

• Explainer — Full explanation (5-15 min)
• Brief — Quick summary (1-3 min)

"Generate a kawaii-style brief video overview for my Security Research notebook"

get_video_status — Check Generation Progress

Video generation takes 3-10 minutes. Check progress:

"Check video status for my Security Research notebook"
→ { "status": "generating", "progress": 0 }
→ { "status": "ready" }

generate_data_table — Structured Data Extraction

Generate a structured table from your notebook sources. NotebookLM extracts key information into rows and columns:

"Generate a data table for my research notebook"

get_data_table — Extract Table as JSON

Extract the generated table as structured JSON for processing:

"Get the data table from my research notebook"
→ {
    "headers": ["Title", "Year", "Key Finding", "Methodology", ...],
    "rows": [["Paper A", "2025", "Finding X", "Survey", ...], ...],
    "totalRows": 27,
    "totalColumns": 7
  }

When to Use Which Studio Feature

📊 Query History & Chat Extraction (v2026.1.0)

Track your research and recover conversations from NotebookLM notebooks.

get_query_history — Review Past Research (v1.10.8)

All queries made through the MCP are automatically logged for review:

"Show me my recent NotebookLM queries"
"Find queries about security from last week"
"What did I ask the fine-tuning notebook?"

• Automatic logging — every Q&A pair saved with metadata
• Search — find specific topics across all queries
• Filter — by notebook, session, or date
• Quota tracking — see query counts and timing

get_notebook_chat_history — Extract Browser Conversations (v2026.1.0)

Extract conversation history directly from a NotebookLM notebook's chat UI with context management to avoid overwhelming your AI context window:

Quick audit (preview mode):

{ "notebook_id": "my-research", "preview_only": true }

Returns message counts without content — test the water before extracting.

Export to file (avoids context overflow):

{ "notebook_id": "my-research", "output_file": "/tmp/chat-history.json" }

Dumps full history to disk instead of returning to context.

Paginate through history:

{ "notebook_id": "my-research", "limit": 20, "offset": 0 }
{ "notebook_id": "my-research", "limit": 20, "offset": 20 }

Page through large histories without loading everything at once.

Returns:

{
  "notebook_url": "https://notebooklm.google.com/notebook/xxx",
  "notebook_name": "My Research",
  "total_messages": 150,
  "returned_messages": 40,
  "user_messages": 75,
  "assistant_messages": 75,
  "offset": 0,
  "has_more": true,
  "messages": [...]
}

Use cases:

• Recover conversations made directly in the NotebookLM browser (not tracked by MCP)
• Audit research — see what queries were made in a notebook
• Resume context — pick up where a previous session left off
• Quota reconciliation — understand why quota seems off

Why This Fork?

The original NotebookLM MCP is excellent for productivity — but MCP servers handle sensitive data:

• Browser sessions with Google authentication
• Cookies and tokens stored on disk
• Query history that may contain proprietary information

This fork adds 17 security hardening layers to protect that data.

Security Features

Post-Quantum Ready

Traditional encryption (RSA, ECDH) will be broken by quantum computers. This fork uses hybrid encryption:

ML-KEM-768 (Kyber) + ChaCha20-Poly1305

• ML-KEM-768: NIST-standardized post-quantum key encapsulation
• ChaCha20-Poly1305: Modern stream cipher (immune to timing attacks)

Even if one algorithm is broken, the other remains secure.

Cross-Platform Support

Full native support for all major operating systems:

All sensitive files (encryption keys, auth tokens, audit logs) are automatically protected with owner-only permissions on every platform.

Enterprise Compliance-Ready Architecture (v1.6.0+)

Built to the standards required for regulated industries. All controls are implemented — formal certification (SOC2 Type II report, GDPR registration, CSSF submission) requires a third-party audit engagement.

Compliance Tools (16 MCP tools)

compliance_dashboard    - Real-time compliance status
compliance_report       - Generate audit reports (JSON/CSV/HTML)
compliance_evidence     - Collect evidence packages
grant_consent          - Record user consent
submit_dsar            - Handle data subject requests
request_erasure        - Right to be forgotten
export_user_data       - Data portability export
create_incident        - Security incident management
...and 8 more

See COMPLIANCE-SPEC.md for full documentation.

Installation

What Works Out of the Box (No API Key)

All core NotebookLM features work immediately with just browser authentication:

Optional: Add GEMINI_API_KEY for bonus features like deep_research, gemini_query, and upload_document.

# Multi-Session Support (v2026.1.2+)
NOTEBOOK_PROFILE_STRATEGY=isolated  # isolated|single|auto
NOTEBOOK_CLONE_PROFILE=true         # Clone auth from base profile

Multi-Session Mode

Run multiple Claude Code sessions simultaneously with isolated browser profiles:

# Add to ~/.bashrc or ~/.zshrc
export NOTEBOOK_PROFILE_STRATEGY=isolated
export NOTEBOOK_CLONE_PROFILE=true

How it works:

• Each session gets its own Chrome profile (no lock conflicts)
• Isolated profiles clone from the authenticated base profile
• Auth coordination ensures cloning waits for any in-progress authentication

See SECURITY.md for complete configuration reference.

Security Scanning

Run MEDUSA security scanner:

npm run security-scan

Or integrate in CI/CD:

- name: Security Scan
  run: npx @pan-sec/notebooklm-mcp && npm run security-scan

Comparison

vs Other NotebookLM MCPs

Security & Compliance (Unique to This Fork)

* Compliance-ready: all required controls are implemented. Formal certification (SOC2 Type II report, GDPR registration, CSSF submission) requires a third-party audit engagement.

Bottom line: If you need more than basic queries, or care about security, there's only one choice.
