Checkout.com MCP server

What the model can do

Checkout.com payments: list and search payments by status, currency, email or reference, a payment's details and its authorisation, capture and refund history, disputes with their deadlines, reports, and payment links. Can capture, refund or void an existing payment, accept a dispute or attach written evidence to it, create a payment link, and create or update a customer, each only when asked; never starts a new charge, payout or transfer.

Acts, when you ask

These change something in Checkout.com. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• checkoutcom_create_payment_linkCreate a Checkout.com payment link for an amount, currency and your reference, and return its URL.
• checkoutcom_create_customerCreate a Checkout.com customer record with an email address and optionally a name, and return its id (cus_…).

• checkoutcom_refund_paymentRefunds a captured Checkout.com payment to the customer: the amount given in minor units, or the whole amount with full_amount true.
• checkoutcom_void_paymentVoids an authorised Checkout.com payment that has not been captured, releasing the hold on the customer's funds: the amount given in minor units…
• checkoutcom_accept_disputeAccepts a Checkout.com dispute without contesting it: the dispute closes and the chargeback stands, so the disputed amount is lost.
• checkoutcom_provide_dispute_evidenceAttaches written evidence to a Checkout.com dispute, without submitting it: nothing is sent to the card scheme until someone submits it in the…
• checkoutcom_update_customerChanges a stored Checkout.com customer's email address or name.

Connect it

First connect Checkout.com on Dashboard → Connections, then add Memtro to your client once. The Checkout.com tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Checkout.com connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official Checkout.com MCP server?

No. It is Memtro's MCP server with Memtro's Checkout.com connector behind it: the connector reads Checkout.com through its API with the credentials you connect on Dashboard → Connections, and Checkout.com publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Checkout.com?

Only when you ask, and only what it has been granted: create a payment link for an amount, currency and reference (nobody is charged until someone pays it); create a customer record with an email and name; capture an authorised Checkout.com payment, in full or in part (takes the customer's money); refund a captured Checkout.com payment, in full or in part (money goes back to the customer); void an authorised Checkout.com payment before capture (releases the hold on the customer's funds); accept a Checkout.com dispute without contesting it (the chargeback stands); attach written evidence to a Checkout.com dispute (not submitted); update a Checkout.com customer's email or name. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
