How do I connect my Checkout.com account?

You subscribe to the MCP on Vinkius and enter your Secret API Key. You can choose between Sandbox for testing or Live for real transactions.

Which AI clients can I use with this MCP?

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

Can I test payments without using real money?

Yes, you can select the Sandbox environment during setup to test payment flows safely.

Is my payment data secure?

The MCP uses your Checkout.com credentials to interact with the official Vault and gateway, maintaining standard security protocols.

What happens if a payment is voided?

Voiding a payment drops the limits before the capture is finalized, which helps you avoid heavy gateway fees.

Can my agent help me debug why a payment failed?

Yes. Ask your agent to get payment actions for a specific ID. It returns a detailed trace of everything that happened at the gateway level, identifying exactly why an authorization fell through, from CVV checks to insufficient funds.

Is it safe to manage card instruments via the AI agent?

Absolutely. The server uses Checkout.com's native Vault logic. Sensitive PANs are wrapped safely, and your API keys are encrypted at rest. The agent only interacts with tokens or vaulted IDs, maintaining high security standards.

Can I test this in sandbox before going live?

Yes. Simply choose the 'Sandbox' environment during setup and use your sandbox secret key (sk_sbox_...). This allows you to simulate transactions and vaulting logic without processing real money.

Waiting for input…

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 Checkout.com 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

Checkout.com 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 Checkout.com 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.
