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.

A futuristic MCP client docking bay
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.

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

Highnote 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 Highnote 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 Highnote, so you can see the experience inside your AI.

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

FAQ

Questions Highnote owners ask.

    Which AI clients can I use with this MCP?

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

  • 03

    Can I freeze a card using my AI agent?

    Yes. You can use the update_card_status capability to change a card to FROZEN or CLOSED immediately.

  • 04

    Is this for testing or production?

    The MCP supports both. You select your Environment (Test or Live) when you configure your credentials.

  • 05

    Does this work with GraphQL?

    This MCP acts as a bridge, so you don't have to write or run manual GraphQL queries to get your data.

  • 06

    How do I find my Highnote API Key?

    Log in to your Highnote dashboard, navigate to Settings > API, and you will be able to generate and copy your API key. Make sure to distinguish between Test and Live keys based on your environment.

  • 07

    What environments are supported?

    The integration supports both the Test (Sandbox) and Live (Production) environments. You must specify which one you are connecting to during setup to ensure the correct API endpoints are used.

  • 08

    Can I freeze a card through this integration?

    Yes! Use the update_card_status capability and set the status to FROZEN. This will immediately prevent any new authorizations on that card. You can set it back to ACTIVE to unfreeze it.

    Is the integration secure for financial data?

    Absolutely. The integration uses industry-standard Basic Authentication over HTTPS. Your credentials and financial data are encrypted and stored securely within the Vinkius Cloud infrastructure.
