| **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.**

"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 |

## 📊 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 |
| 🔍 | **Secrets Scanning** | Detects 30+ credential patterns (AWS, GitHub, Slack...) |
| 📌 | **Certificate Pinning** | Blocks MITM attacks on Google connections |
| 🧹 | **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 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:

| 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 controls are implemented — 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
```

## Configuration

All security features are **enabled by default**. Override via environment variables:

```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

# Certificate Pinning
NLMCP_CERT_PINNING=true

# 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
```
