What is the Notesnook MCP Server?
The Notesnook MCP Server gives AI agents like Claude, ChatGPT, and Cursor direct access to Notesnook via 12 tools. Manage encrypted notes via Notesnook — create secure entries, sync your vault, and audit private notebooks. Powered by the Vinkius - no API keys, no infrastructure, connect in under 2 minutes.
Built-in capabilities (12)
Tools for your AI Agents to operate Notesnook
Ask your AI agent "List the last 5 encrypted notes in my vault" and get the answer without opening a single dashboard. With 12 tools connected to real Notesnook data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.
Why teams choose Vinkius
One subscription gives you access to thousands of MCP servers - and you can deploy your own to the Vinkius Edge. Your AI agents only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure and security, zero maintenance.

Notesnook (Private Note Taking & E2EE) MCP Server capabilities
12 toolsThis 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
Destroys the node logic completely inside the encrypted persistence layer. Irreversibly delete a specific encrypted note from the server
Retrieve the underlying encrypted cipher payload of a single note
Validate the authenticated Notesnook user security identity
List encapsulated binary attachments mapped against notes
List high-priority specific notes flagged as favorites
Critical for correlating hierarchical IDs before exploring note clusters. List boundary organizing Notebooks spanning the vault
Indispensable for discovering target node IDs prior to fetching decryption contexts. List all encrypted notes securely stored in the Notesnook vault
List cross-cutting categorical classification Tags indexing Notes
Identifies tracking records physically slated for permanent erasure. List nodes trapped inside the local vault waste bin
Yields encrypted binary objects based on the last sync timestamp boundaries. Trigger a full sync with the Notesnook server resolving vault state
Updates synchronization timelines and forces re-encryption across the specific item payload. Modify partial strings within a pre-existing encrypted vault note
What the Notesnook (Private Note Taking & E2EE) MCP Server unlocks
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

Frequently asked questions about the Notesnook (Private Note Taking & E2EE) MCP Server
How does Notesnook ensure my notes remain private through the agent?
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.
Can I see all my notebooks and tags using my agent?
Yes. Use the list_notebooks and list_tags tools to retrieve the organizational hierarchy of your vault. Your agent will report the names and IDs, helping you understand how your encrypted information is classified across your account.
How do I trigger a synchronization between my vault and the server?
The sync_items tool allows your agent to initiate a full or incremental state resolution. By providing a Unix timestamp, your agent can fetch only the most recent encrypted binary objects, ensuring your local environment matches the server's state.
