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.

Put Kit 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

Kit 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 Kit 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 10 capabilities arrive ready to run.

Preview access · not provider authentication

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

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

FAQ

Questions Kit owners ask.

  • 01

    How do I connect this MCP to my Kit account?

    You need to provide your Kit API Secret, which you can find in your Kit account under Settings and then Advanced.

  • 02

    Which AI clients can use this Kit MCP?

    This MCP works with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

  • 03

    Can I use this to add new subscribers?

    Yes, you can use the capability to add subscribers to specific forms through your AI client.

  • 04

    Is my Kit API Secret kept secure?

    Yes, Vinkius manages your credentials securely so your AI client can perform actions on your behalf.

  • 05

    Can I see my email campaign stats?

    Yes, your agent can retrieve open rates, click-through metrics, and other campaign statuses.

  • 06

    How do I find my Kit API Secret?

    Log in to Kit, go to Settings > Advanced. Under 'API', click Show next to API Secret, copy the string, and paste it below.

  • 07

    Why is the API Secret required instead of the standard API Key?

    The API Key only provides read access to public forms. The API Secret grants full access to manage subscribers, tags, and broadcast data as needed by this integration.

  • 08

    Can the agent send broadcast emails?

    No. For safety, the integration is read/manage only. The agent can check campaign metrics and manage tags, but actual email sending must be done via the Kit dashboard.
