NotebookLM CLI & MCP Expert
This skill provides comprehensive guidance for using NotebookLM via both the nlm CLI and MCP tools.
Tool Detection (CRITICAL - Read First!)
ALWAYS check which tools are available before proceeding:
- Check for MCP tools: Look for tools starting with
mcp__notebooklm-mcp__* or mcp_notebooklm_*
- If BOTH MCP tools AND CLI are available: ASK the user which they prefer to use before proceeding
- If only MCP tools are available: Use them directly (refer to tool docstrings for parameters)
- If only CLI is available: Use
nlm CLI commands via Bash
Decision Logic:
has_mcp_tools = check_available_tools() # Look for mcp__notebooklm-mcp__* or mcp_notebooklm_*
has_cli = check_bash_available() # Can run nlm commands
if has_mcp_tools and has_cli:
# ASK USER: "I can use either MCP tools or the nlm CLI. Which do you prefer?"
user_preference = ask_user()
else if has_mcp_tools:
# Use MCP tools directly
mcp__notebooklm-mcp__notebook_list()
else:
# Use CLI via Bash
bash("nlm notebook list")
This skill documents BOTH approaches. Choose the appropriate one based on tool availability and user preference.
Quick Reference
Run nlm --ai to get comprehensive AI-optimized documentation - this provides a complete view of all CLI capabilities.
nlm --help
nlm <command> --help
nlm --ai
nlm --version
Critical Rules (Read First!)
- Always authenticate first: Run
nlm login before any operations
- Sessions expire in ~20 minutes: Re-run
nlm login if commands start failing
- ⚠️ ALWAYS ASK USER BEFORE DELETE: Before executing ANY delete command, ask the user for explicit confirmation. Deletions are irreversible. Show what will be deleted and warn about permanent data loss.
--confirm is REQUIRED: All generation and delete commands need --confirm or -y (CLI) or confirm=True (MCP)- Research requires
--notebook-id: The flag is mandatory, not positional
- Capture IDs from output: Create/start commands return IDs needed for subsequent operations
- Use aliases: Simplify long UUIDs with
nlm alias set <name> <uuid>
- Check aliases before creating: Run
nlm alias list before creating a new alias to avoid conflicts with existing names.
- DO NOT launch REPL: Never use
nlm chat start - it opens an interactive REPL that AI tools cannot control. Use nlm notebook query for one-shot Q&A instead.
- Choose output format wisely: Default output (no flags) is compact and token-efficient—use it for status checks. Use
--quiet to capture IDs for piping. Only use --json when you need to parse specific fields programmatically.
- Use
--help when unsure: Run nlm <command> --help to see available options and flags for any command.
Workflow Decision Tree
Use this to determine the right sequence of commands:
User wants to...
│
├─► Work with NotebookLM for the first time
│ └─► nlm login → nlm notebook create "Title"
│
├─► Add content to a notebook
│ ├─► From a URL/webpage → nlm source add <nb-id> --url "https://..."
│ ├─► From YouTube → nlm source add <nb-id> --url "https://youtube.com/..."
│ ├─► From pasted text → nlm source add <nb-id> --text "content" --title "Title"
│ ├─► From Google Drive → nlm source add <nb-id> --drive <doc-id> --type doc
│ └─► Discover new sources → nlm research start "query" --notebook-id <nb-id>
│
├─► Generate content from sources
│ ├─► Podcast/Audio → nlm audio create <nb-id> --confirm
│ ├─► Written summary → nlm report create <nb-id> --confirm
│ ├─► Study materials → nlm quiz/flashcards create <nb-id> --confirm
│ ├─► Visual content → nlm mindmap/slides/infographic create <nb-id> --confirm
│ ├─► Video → nlm video create <nb-id> --confirm
│ └─► Extract data → nlm data-table create <nb-id> "description" --confirm
│
├─► Ask questions about sources
│ └─► nlm notebook query <nb-id> "question"
│ (Use --conversation-id for follow-ups)
│ ⚠️ Do NOT use `nlm chat start` - it's a REPL for humans only
│
├─► Check generation status
│ └─► nlm studio status <nb-id>
│
└─► Manage/cleanup
├─► List notebooks → nlm notebook list
├─► List sources → nlm source list <nb-id>
├─► Delete source → nlm source delete <source-id> --confirm
└─► Delete notebook → nlm notebook delete <nb-id> --confirm
Command Categories
1. Authentication
MCP Authentication
If using MCP tools and encountering authentication errors:
nlm login
mcp__notebooklm-mcp__refresh_auth()
Or manually save cookies via MCP (fallback):
mcp__notebooklm-mcp__save_auth_tokens(cookies="<cookie_header>")
#### CLI Authentication
```bash
nlm login # Launch browser, extract cookies (primary method)
nlm login --check # Validate current session
nlm login --profile work # Use named profile for multiple accounts
nlm login --provider openclaw --cdp-url http://127.0.0.1:18800 # External CDP provider
nlm login switch <profile> # Switch the default profile
nlm login profile list # List all profiles with email addresses
nlm login profile delete <name> # Delete a profile
nlm login profile rename <old> <new> # Rename a profile
Multi-Profile Support: Each profile gets its own isolated browser session (supports Chrome, Arc, Brave, Edge, Chromium, and more), so you can be logged into multiple Google accounts simultaneously.
Session lifetime: ~20 minutes. Re-authenticate when commands fail with auth errors.
Switching MCP Accounts: The MCP server always uses the active default profile. If you need to switch which Google account the MCP server is communicating with, you MUST use the CLI: run nlm login switch <name>. Your next MCP tool call will instantly use the new account.
Note: Both MCP and CLI share the same authentication backend, so authenticating with one works for both.
2. Notebook Management
MCP Tools
Use tools: notebook_list, notebook_create, notebook_get, notebook_describe, notebook_query, notebook_rename, notebook_delete. All accept notebook_id parameter. Delete requires confirm=True.

quiz | question_count, difficulty: easy/medium/hard |
flashcards | difficulty: easy/medium/hard |
mind_map | title |
slide_deck | slide_format: detailed_deck/presenter_slides, slide_length: short/default |
infographic | orientation: landscape/portrait/square, detail_level: concise/standard/detailed, infographic_style: auto_select/sketch_note/professional/bento_grid/editorial/instructional/bricks/clay/anime/kawaii/scientific |
data_table | description (REQUIRED) |
Common options: source_ids, language (BCP-47 code), focus_prompt
Revise Slides: Use studio_revise to revise individual slides in an existing slide deck.
- Requires
artifact_id (from studio_status) and slide_instructions
- Creates a NEW artifact — the original is not modified
- Slide numbers are 1-based (slide 1 = first slide)
- Poll
studio_status after calling to check when the new deck is ready
CLI Commands
All generation commands share these flags:
--confirm or -y: REQUIRED to execute--source-ids <id1,id2>: Limit to specific sources--language <code>: BCP-47 code (en, es, fr, de, ja)
nlm audio create <id> --confirm
nlm audio create <id> --format deep_dive --length default --confirm
nlm audio create <id> --format brief --focus "key topic" --confirm
nlm report create <id> --confirm
nlm report create <id> --format "Study Guide" --confirm
nlm report create <id> --format "Create Your Own" --prompt "Custom..." --confirm

nlm video create <id> --confirm
nlm video create <id> --format brief --style whiteboard --confirm
nlm data-table create <id> "Extract all dates and events" --confirm
6. Studio (Artifact Management)
MCP Tools
Use studio_status to check progress (or rename with action="rename"). Use download_artifact with artifact_type and output_path. Use export_artifact with export_type: docs/sheets. Delete with studio_delete (requires confirm=True).
CLI Commands
nlm studio status <nb-id>
nlm studio status <nb-id> --full
nlm studio status <nb-id> --json
nlm download audio <nb-id> --output podcast.mp3
nlm download video <nb-id> --output video.mp4
nlm download report <nb-id> --output report.md
nlm download slide-deck <nb-id> --output slides.pdf
nlm download slide-deck <nb-id> --output slides.pptx --format pptx
nlm download quiz <nb-id> --output quiz.json --format json
nlm export sheets <nb-id> <artifact-id> --title "My Data Table"
nlm export docs <nb-id> <artifact-id> --title "My Report"
nlm studio delete <nb-id> <artifact-id> --confirm
Status values: completed (✓), in_progress (●), failed (✗)
Prompt Extraction: The studio_status tool returns a custom_instructions field for each artifact. This contains the original focus prompt or custom instructions used to generate that artifact (e.g., the prompt for a "Create Your Own" report, or the focus topic for an Audio Overview). This is useful for retrieving the exact prompt that generated a successful artifact.
Renaming Resources
Rename a Source
MCP Tool: source_rename(notebook_id, source_id, new_title)
CLI:
nlm source rename <source-id> "New Title" --notebook <notebook-id>
nlm rename source <source-id> "New Title" --notebook <notebook-id>
Rename a Studio Artifact
MCP Tools
Use studio_status with action="rename", artifact_id, and new_title.
CLI Commands
nlm studio rename <artifact-id> "New Title"
nlm rename studio <artifact-id> "New Title"
Server Info (Version Check)
MCP Tools
Use server_info to get version and check for updates:
mcp__notebooklm-mcp__server_info()
CLI Commands
nlm --version
7. Chat Configuration and Notes
MCP Tools
Use chat_configure with goal: default/learning_guide/custom. Use note with action: create/list/update/delete. Delete requires confirm=True.
CLI Commands
⚠️ AI TOOLS: DO NOT USE nlm chat start - It launches an interactive REPL that cannot be controlled programmatically. Use nlm notebook query for one-shot Q&A instead.
For human users at a terminal:
nlm chat start <nb-id>
REPL Commands:
/sources - List available sources/clear - Reset conversation context/help - Show commands/exit - Exit REPL
Configure chat behavior (works for both REPL and query):
nlm chat configure <id> --goal default
nlm chat configure <id> --goal learning_guide
nlm chat configure <id> --goal custom --prompt "Act as a tutor..."
nlm chat configure <id> --response-length longer
Notes management:
nlm note create <nb-id> "Content" --title "Title"
nlm note list <nb-id>
nlm note update <nb-id> <note-id> --content "New content"
nlm note delete <nb-id> <note-id> --confirm
8. Notebook Sharing
MCP Tools
Use notebook_share_status to check, notebook_share_public to enable/disable public link, notebook_share_invite with email and role: viewer/editor.
CLI Commands
nlm share status <nb-id>
nlm share public <nb-id>
nlm share public <nb-id> --off
nlm share invite <nb-id> user@example.com
nlm share invite <nb-id> user@example.com --role editor
9. Aliases (UUID Shortcuts)
Simplify long UUIDs:
nlm alias set myproject abc123-def456...
nlm alias get myproject
nlm alias list
nlm alias delete myproject
nlm notebook get myproject
nlm source list myproject
nlm audio create myproject --confirm
10. Configuration
CLI-only commands for managing settings:
nlm config show
nlm config get <key>
nlm config set <key> <value>
nlm config set output.format json
nlm login switch work
Available Settings:
| Key | Default | Description |
|---|
output.format | table | Default output format (table, json) |
output.color | true | Enable colored output |
output.short_ids | true | Show shortened IDs |
auth.browser | auto | Preferred browser for login (auto, chrome, arc, brave, edge, chromium, vivaldi, opera) |
auth.default_profile | default | Profile to use when --profile not specified |
11. Skill Management
Manage the NotebookLM skill installation for various AI assistants:
nlm skill list
nlm skill update
nlm skill update <tool>
nlm skill install <tool>
nlm skill uninstall <tool>
Verb-first aliases: nlm update skill, nlm list skills, nlm install skill
Output Formats
Most list commands support multiple formats:

--json | JSON output (for parsing) |
--quiet | IDs only (for piping) |
--title | "ID: Title" format |
--url | "ID: URL" format (sources only) |
--full | All columns/details |
12. Batch Operations
Perform the same action across multiple notebooks at once.
MCP Tools
Use batch with action parameter. Select notebooks by notebook_names, tags, or all=True.
batch(action="query", query="What are the key findings?", notebook_names="AI Research, Dev Tools")
batch(action="add_source", source_url="https://example.com", tags="ai,research")
batch(action="create", titles="Project A, Project B, Project C")
batch(action="delete", notebook_names="Old Project", confirm=True)
batch(action="studio", artifact_type="audio", tags="research", confirm=True)
CLI Commands
nlm batch query "What are the key takeaways?" --notebooks "id1,id2"
nlm batch query "Summarize" --tags "ai,research"
nlm batch query "Summarize" --all
nlm batch add-source --url "https://..." --notebooks "id1,id2"
nlm batch create "Project A, Project B, Project C"
nlm batch delete --notebooks "id1,id2" --confirm
nlm batch studio --type audio --tags "research" --confirm
13. Cross-Notebook Query
Query multiple notebooks and get aggregated answers with per-notebook citations.
MCP Tools
cross_notebook_query(query="Compare approaches", notebook_names="Notebook A, Notebook B")
cross_notebook_query(query="Summarize", tags="ai,research")
cross_notebook_query(query="Everything", all=True)
CLI Commands

14. Pipelines
Define and execute multi-step notebook workflows. Three built-in pipelines plus support for custom YAML pipelines.
MCP Tools
pipeline(action="list")
pipeline(action="run", notebook_id="...", pipeline_name="ingest-and-podcast", input_url="https://...")
CLI Commands
nlm pipeline list
nlm pipeline run <notebook> ingest-and-podcast --url "https://..."
nlm pipeline run <notebook> research-and-report --url "https://..."
nlm pipeline run <notebook> multi-format
Built-in pipelines: ingest-and-podcast, research-and-report, multi-format
Create custom pipelines: add YAML files to ~/.notebooklm-mcp-cli/pipelines/
15. Tags & Smart Select
Tag notebooks for organization and use tags to target batch operations.
MCP Tools
tag(action="add", notebook_id="...", tags="ai,research,llm")
tag(action="remove", notebook_id="...", tags="ai")
tag(action="list")
tag(action="select", query="ai research")

Error Recovery
| Error | Cause | Solution |
|---|
| "Cookies have expired" | Session timeout | nlm login |
| "authentication may have expired" | Session timeout | nlm login |
| "Notebook not found" | Invalid ID | nlm notebook list |
| "Source not found" | Invalid ID | nlm source list <nb-id> |
| "Rate limit exceeded" | Too many calls | Wait 30s, retry |
| "Research already in progress" | Pending research | Use --force or import first |
| "Import timed out" | Too many sources | Use --timeout 600 for larger notebooks |
| "Google API error code 3" | Transient deep research error | Retry in a few minutes, or use --mode fast |
| Browser doesn't launch | Port conflict | Close browser, retry |
Rate Limiting
Wait between operations to avoid rate limits:
