More Details Connect to Claude

Connect your Notesnook account to any AI agent and take full control of your privacy-first knowledge base, zero-knowledge note taking, and secure vault synchronization through natural conversation.

What you can do

  • Encrypted Orchestration — List all secure notes and retrieve detailed encrypted payloads including raw text and binary history directly from your agent
  • Vault Synchronization — Trigger a full sync with the Notesnook server to resolve encrypted state changes and ensure your local representation is up-to-date
  • Secure Note Injection — Instantly create and attach brand new encrypted notes to your vault, securely pushing plaintext into persistent encrypted envelopes natively
  • Notebook Navigation — Explore hierarchical notebook groupings to understand your knowledge organization and categorize secure notes across project boundaries
  • Metadata & Tag Audit — Enumerate cross-cutting categorical tags and classification indices to identify related information through metadata parameters securely
  • Attachment Visibility — List encapsulated binary attachments mapping images, PDFs, and embedded blobs stored persistently inside your encrypted notes
  • Lifecycle Management — Update partial strings within existing notes or irreversibly delete specific entries to maintain a clean and relevant secure workspace

How it works

  1. Subscribe to this server
  2. Enter your Notesnook Sync URL and Auth Token
  3. Start managing your private vault from Claude, Cursor, or any MCP-compatible client

12 tools expose this connector's capabilities to your AI agent.

sync_items

Yields encrypted binary objects based on the last sync timestamp boundaries. Trigger a full sync with the Notesnook server resolving vault state

list_notes

Indispensable for discovering target node IDs prior to fetching decryption contexts. List all encrypted notes securely stored in the Notesnook vault

get_note

Retrieve the underlying encrypted cipher payload of a single note

create_note

This will securely push plaintext into an encrypted envelope stored persistently in the Notesnook sync server. Create and inject a brand new encrypted note into the vault

update_note

Updates synchronization timelines and forces re-encryption across the specific item payload. Modify partial strings within a pre-existing encrypted vault note

delete_note

Destroys the node logic completely inside the encrypted persistence layer. Irreversibly delete a specific encrypted note from the server

list_notebooks

Critical for correlating hierarchical IDs before exploring note clusters. List boundary organizing Notebooks spanning the vault

list_tags

List cross-cutting categorical classification Tags indexing Notes

list_trash

Identifies tracking records physically slated for permanent erasure. List nodes trapped inside the local vault waste bin

list_favorites

List high-priority specific notes flagged as favorites

list_attachments

List encapsulated binary attachments mapped against notes

get_user

Validate the authenticated Notesnook user security identity

List the last 5 encrypted notes in my vault

I've retrieved your recent encrypted notes. Highlights include 'Project Alpha Strategy' (ID: note-123), 'Meeting Notes: Backend' (ID: note-456), and 'Research Snippets'. Would you like me to fetch the encrypted payload for the strategy note?

Create a new private note called 'Ideas 2026' with content 'Automated note generation via AI'

New encrypted note 'Ideas 2026' has been successfully created and injected into your persistent vault. The note is now synced and secured with end-to-end encryption. New Note ID: 'note-98765'.

Show me all my classified tags in Notesnook

Retrieving tags… I've identified 4 cross-cutting categories in your vault: 'Confidential', 'Drafts', 'Research', and 'Personal'. I can help you list all notes associated with the 'Confidential' tag if you'd like.

Notesnook uses end-to-end encryption (E2EE). When your agent uses the `create_note` or `get_note` tools, it handles encrypted envelopes. This ensures that only authorized clients with your keys can decrypt the actual text body, maintaining zero-knowledge security natively.
