Is my data safe with this MCP?

Yes. This MCP uses Notesnook's end-to-end encryption, meaning your data remains in a zero-knowledge vault.

Which AI clients can I use?

You can use any MCP-compatible client, including Claude, Cursor, and Windsurf.

Do I need to provide my password?

No, you use your Notesnook Sync URL and Auth Token to establish the connection.

Can the AI see my notes in plaintext?

The AI client processes the data you request, but the underlying storage remains protected by Notesnook's encryption architecture.

Can I delete notes using the AI?

Yes, you can instruct your agent to irreversibly delete specific notes from your vault.

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 capabilities, 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 capabilities 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 capability 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.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Notesnook to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Notesnook works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Notesnook to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Notesnook, so you can see the experience inside your AI.

It does not authenticate your account with Notesnook. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
