## 🚀 What's New in 2026

**Latest: v2026.3.1** — All 334 audit issues resolved. 631 tests. Full MCP protocol compliance.

| Version | Highlights |
|---------|------------|
| **v2026.3.1** | **Security Audit Complete** — All 334 issues from the independent audit resolved. Tests: 609 → 631. Code quality: URL resolution deduplicated, handler extraction, non-null assertions eliminated. Test gaps closed: `validateNotebookId`, error body shape, `delete_document` confirm guard, sanitized throws, log rotation, rate-limiter memory bound, range clamping. |
| **v2026.3.0** | **The Security Audit Release** — Four parallel AI code reviews (security, protocol, architecture, testing) against 334 issues. All highs and mediums resolved. Tests: 139 → 609 across 50 files (4.4×). Full MCP protocol compliance: structuredContent, isError, transport tags. Schema bounds on all 48 tools. Annotation correctness. Webhook SSRF fix. Audit log integrity (hash chain, concurrent write lock, rotation continuity). Per-page mutex. HandlerContext DI. Cert pinning retracted (claims aligned with implementation). |
| **v2026.2.10** | **The Hardening Release** — 3 new security layers (14→17): secure-by-default auth, exponential backoff lockout, credential isolation. Architecture overhaul: 3,611-line handler split into 9 domain modules, tool registry pattern. Gemini API retry with backoff. Multi-stage Docker build. Token CLI (`token show/rotate`). 168 tests. |
| **v2026.2.9** | `performSetup` no longer wipes credentials before Chrome opens — prevents auth destruction on failed launch |
| **v2026.2.8** | `cleanup_data` never deletes auth dirs (`browser_state/`, `chrome_profile/`) — auth survives all cleanup paths |
| **v2026.2.7** | Block headless `setup_auth` calls; robust `auth-now.mjs` standalone script with Chrome profile lock handling |
| **v2026.2.6** | New `add_folder` tool for bulk PDF/file uploads; improved tier detection for NotebookLM Plus |
| **v2026.2.5** | Fix `show_browser` silently ignored in `setup_auth` — browser now reliably opens for auth |

## 🔬 Security Audit 2026 — What We Found and Fixed

In April 2026, we commissioned a parallel deep-audit of v2026.2.11 (`main @ 2973097`) using four specialised AI code reviewers, each focused on a different attack surface: **security vulnerabilities**, **protocol correctness**, **architecture quality**, and **testing gaps and edge cases**. The four reviewers operated independently so their findings wouldn't influence each other. Together they produced a **334-item master issue list** covering protocol correctness, security vulnerabilities, architecture flaws, test gaps, and documentation accuracy. All 334 issues are resolved across v2026.3.0 and v2026.3.1.

### Audit by the Numbers

| Metric | Before (v2026.2.11) | After (v2026.3.1) |
|--------|---------------------|--------------------|
| Tests | 139 | **631 across 50 files** |
| Test suites | ~6 | **50** |
| TypeScript errors (`tsc --noEmit`) | 0 | **0 (maintained)** |
| npm audit vulnerabilities | 0 | **0 (maintained)** |
| MCP protocol compliance | Partial | **Full** (structuredContent, isError, transport tags) |
| Audit log integrity | Basic | **Hash-chain verified on read** |
| Concurrent write safety | ❌ | **✅ Write-locked** |
| Webhook SSRF | ❌ | **✅ Blocked** |

### What the Four Reviewers Found

**Security reviewer:** Identified the `forceAuth` bypass in `validateToken()` allowing unauthenticated access to filesystem tools; webhook SSRF via unvalidated delivery targets; audit log hash chain not verified on read; concurrent audit writes interleaving entries; auth token salt not persisted (tokens invalidated on restart).

**Protocol reviewer:** Found 38 tools returning incorrect response shapes (missing `structuredContent`, wrong `isError` semantics, transport tags leaking into content); all 48 tools had incorrect or missing `readOnlyHint`/`idempotentHint`/`destructiveHint` annotations; 9 tool schemas lacked numeric bounds, enabling out-of-range inputs.

**Architecture reviewer:** Flagged the 3,611-line `handlers.ts` as a maintenance liability; singleton imports throughout domain functions preventing unit testing; the 500-line `switch/case` dispatch adding O(n) overhead and making tool registration error-prone.

**Testing & edge-case reviewer:** Found test suite at 139 tests with minimal coverage of security-critical modules; `mcp-auth.ts` at near-zero coverage; no tests for prompt injection patterns, audit log tampering, or concurrent browser session state; the DSAR handler had an undetected race condition.

### Key Fixes

- **17 security vulnerabilities** addressed (auth bypass, SSRF, audit integrity, race conditions, selector injection vectors)
- **MCP protocol fully compliant** — all 48 tools return correct `structuredContent`/`isError` shapes; annotations accurate; schema bounds enforced
- **Architecture decomposed** — `handlers.ts` split into 9 domain modules with HandlerContext dependency injection; 100% unit-testable without process mocks
- **Test coverage** — 15 new security-critical test suites including browser session, auth, prompt injection, audit log, webhook, DSAR, and compliance
- **Claims aligned** — certificate pinning removed (implementation was retracted in Day 1 of the audit); PQ encryption scope documented accurately; compliance language uses "controls implemented" not "certified"

```
"Research the security implications of post-quantum cryptography adoption in financial services"
```

- Runs Google's **Deep Research agent** (same as Gemini Advanced)
- Takes 1-5 minutes for comprehensive, web-grounded analysis
- Returns structured answers with **citations and sources**
- Perfect for complex topics requiring multi-source synthesis

#### `gemini_query` — Fast Grounded Queries

```
"What are the latest CVEs for Log4j in 2025?" (with Google Search)
"Calculate the compound interest on $10,000 at 5% over 10 years" (with code execution)
"Summarize this security advisory: [URL]" (with URL context)
```

- **Google Search grounding** — Current information, not just training data
- **Code execution** — Run calculations, data analysis
- **URL context** — Analyze web pages on demand
- Models: `gemini-3-flash-preview` (default), `gemini-3-pro-preview` (powerful), `gemini-2.5-flash` (legacy)

#### `get_research_status` — Background Task Monitoring

Run deep research in the background and check progress:
```
"Start researching [topic] in the background"
... continue other work ...
"Check research status for interaction_abc123"
```

> **💡 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)

```bash
# 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

| Task | Best Tool | Why |
|------|-----------|-----|
| Questions about YOUR documents | `ask_question` | Grounded on your uploaded sources |
| Comprehensive topic research | `deep_research` | Multi-source synthesis with citations |
| Current events / recent info | `gemini_query` + google_search | Live web data |
| Code calculations | `gemini_query` + code_execution | Reliable computation |
| Analyze a webpage | `gemini_query` + url_context | Direct page analysis |
| **Quick PDF/document analysis** | `upload_document` + `query_document` | **Fast API, no browser** (NEW!) |

---

## 📄 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

| Feature | Browser Mode | Document API |
|---------|--------------|--------------|
| Speed | Seconds | **Milliseconds** |
| Reliability | UI-dependent | **API-stable** |
| File Support | Via NotebookLM | **50MB PDFs, 1000 pages** |
| Retention | Permanent | 48 hours |
| Setup | Auth + cookies | **Just API key** |

### 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

| Scenario | Use |
|----------|-----|
| Quick one-off document analysis | **Document API** — fast, no setup |
| Building a permanent knowledge base | **NotebookLM** — permanent storage |
| Analyzing sensitive documents | **Document API** — 48h auto-delete |
| Multi-source research over time | **NotebookLM** — organized notebooks |
| CI/CD pipeline document processing | **Document API** — API-native |
| **Large PDFs (1000+ pages)** | **Document API** — auto-chunking |

---

## 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:

```json
{
  "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:

```json
{
  "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:

```json
{
  "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:

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

### Why This Matters

| Traditional Workflow | With This MCP |
|---------------------|---------------|
| Manually create notebook in browser | `create_notebook` → done |
| Click "Add source" for each document | Batch add in single command |
| Navigate UI to generate audio | `generate_audio` → podcast ready |
| Update sources by hand | `sync_notebook` from local files |

**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**:

| Style | Description |
|-------|-------------|
| `auto-select` | Let NotebookLM choose the best style (default) |
| `classic` | Clean presentation style |
| `whiteboard` | Hand-drawn whiteboard aesthetic |
| `kawaii` | Cute illustrated style |
| `anime` | Anime-inspired visuals |
| `watercolour` | Watercolour painting style |
| `retro-print` | Retro print aesthetic |
| `heritage` | Traditional heritage style |
| `paper-craft` | Paper-craft visual style |
| `custom` | Custom visual style |

**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

| Task | Best Tool | Why |
|------|-----------|-----|
| Podcast-style audio summary | `generate_audio_overview` | Shareable audio content |
| Visual presentation of research | `generate_video_overview` | Engaging video summary |
| Structured data for analysis | `generate_data_table` + `get_data_table` | Machine-readable JSON |
| Quick status check | `get_audio_status` / `get_video_status` | Non-blocking progress |

## 📊 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):**
```json
{ "notebook_id": "my-research", "preview_only": true }
```
Returns message counts without content — test the water before extracting.

**Export to file (avoids context overflow):**
```json
{ "notebook_id": "my-research", "output_file": "/tmp/chat-history.json" }
```
Dumps full history to disk instead of returning to context.

**Paginate through history:**
```json
{ "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:**
```json
{
  "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

| Layer | Feature | Protection |
|-------|---------|------------|
| 🔐 | **Post-Quantum Encryption** | ML-KEM-768 + ChaCha20-Poly1305 hybrid (local at-rest) |
| 🔍 | **Secrets Scanning** | Detects 30+ credential patterns (AWS, GitHub, Slack...) |
| 🧹 | **Memory Scrubbing** | Zeros sensitive data after use |
| 📝 | **Audit Logging** | Tamper-evident logs with hash chains |
| ⏱️ | **Session Timeout** | 8h hard limit + 30m inactivity auto-logout |
| 🎫 | **MCP Authentication** | Token-based auth with brute-force lockout |
| 🛡️ | **Response Validation** | Detects prompt injection attempts |
| ✅ | **Input Validation** | URL whitelisting, sanitization |
| 🚦 | **Rate Limiting** | Per-session request throttling |
| 🙈 | **Log Sanitization** | Credentials masked in all output |
| 🐍 | **MEDUSA Integration** | Automated security scanning |
| 🖥️ | **Cross-Platform** | Native support for Linux, macOS, Windows |
| 🔒 | **Secure-by-Default Auth** | Auth ON without configuration, explicit opt-out required |
| 📈 | **Exponential Backoff** | Lockout escalation: 5min → 15min → 45min → 4hr cap |
| 🗝️ | **Credential Isolation** | SecureCredential TTL + env var scrubbing from process.env |

### Post-Quantum Primitives (Local At-Rest)

Encryption of secrets on disk uses hybrid post-quantum primitives:

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

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

**Scope, honestly:** this is **local at-rest** encryption. Both keys live
on the same machine — the PQ secret key is wrapped with a classical key
derived from a machine-bound secret, not held by a remote recipient.
This protects against offline theft of individual encrypted files, not
against Harvest-Now-Decrypt-Later attacks (those require a remote PQ
recipient holding the unwrap key).

### Cross-Platform Support

Full native support for all major operating systems:

| Platform | File Permissions | Data Directory |
|----------|-----------------|----------------|
| **Linux** | Unix chmod (0o600/0o700) | `~/.local/share/notebooklm-mcp/` |
| **macOS** | Unix chmod (0o600/0o700) | `~/Library/Application Support/notebooklm-mcp/` |
| **Windows** | ACLs via icacls (current user only) | `%LOCALAPPDATA%\notebooklm-mcp\` |

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 code-level technical controls are implemented — full compliance also requires organizational process controls (policies, training, vendor management). Formal certification (SOC2 Type II report, GDPR registration, CSSF submission) requires a third-party audit engagement.

| Regulation | Controls Implemented |
|------------|----------|
| **GDPR** | Consent management, DSAR handling, right to erasure, data portability |
| **SOC2 Type II** | Hash-chained audit logs, incident response, availability monitoring |
| **CSSF** | 7-year retention, SIEM integration, policy documentation |

#### 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
```

```bash
# Authentication
NLMCP_AUTH_ENABLED=true
NLMCP_AUTH_TOKEN=your-secret-token

# Gemini API (v1.8.0+)
GEMINI_API_KEY=your-api-key
GEMINI_DEFAULT_MODEL=gemini-3-flash-preview  # Default (was gemini-2.5-flash)
GEMINI_DEEP_RESEARCH_ENABLED=true
GEMINI_TIMEOUT_MS=30000
NOTEBOOKLM_NO_GEMINI=false       # Set to true to disable all Gemini tools

# Tool Profiles
NOTEBOOKLM_PROFILE=standard      # minimal (5 tools) | standard (33 tools) | full (all 47)
NOTEBOOKLM_DISABLED_TOOLS=       # Comma-separated list of tools to hide

# Encryption
NLMCP_USE_POST_QUANTUM=true
NLMCP_ENCRYPTION_KEY=base64-32-bytes  # Optional custom key

# Session Limits
NLMCP_SESSION_MAX_LIFETIME=28800  # 8 hours
NLMCP_SESSION_INACTIVITY=1800     # 30 minutes

# Secrets Scanning
NLMCP_SECRETS_SCANNING=true
NLMCP_SECRETS_BLOCK=false         # Block on detection
NLMCP_SECRETS_REDACT=true         # Auto-redact

# Audit Logging
NLMCP_AUDIT_ENABLED=true

# 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:

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

| Variable | Values | Description |
|----------|--------|-------------|
| `NOTEBOOK_PROFILE_STRATEGY` | `single`, `auto`, `isolated` | `isolated` = separate profile per session |
| `NOTEBOOK_CLONE_PROFILE` | `true`, `false` | Clone authenticated base profile into isolated instances |

**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](./SECURITY.md) for complete configuration reference.

## Security Scanning

Run MEDUSA security scanner:

```bash
npm run security-scan
```

Or integrate in CI/CD:

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