Mollie MCP server

What the model can do

Read Mollie payments, customers, subscriptions and refunds for one website profile. When you ask, can refund a payment or cancel a pending refund, create a payment link, cancel an open payment or a subscription, and create, update or delete a customer. Never creates a payment or a mandate.

Acts, when you ask

These change something in Mollie. 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.

• mollie_create_customerCreates a customer record in Mollie (name, email, locale).
• mollie_create_refundRefunds a Mollie payment, fully or partly: moves money out of the merchant balance back to the customer, by bank transfer or to their card.
• mollie_cancel_refundCancels a Mollie refund before it is paid out, which Mollie allows only while its status is queued or pending.
• mollie_create_payment_linkCreates a Mollie payment link and returns its URL.
• mollie_cancel_paymentCancels a Mollie payment that is still open, so it can no longer be paid.
• mollie_cancel_subscriptionCancels a customer's Mollie subscription so no further charges are taken.
• mollie_update_customerChanges a Mollie customer's name, email or locale; only the fields given are sent.
• mollie_delete_customerPermanently deletes a Mollie customer, and with it Mollie cancels all the customer's mandates and subscriptions…

Connect it

First connect Mollie on Dashboard → Connections, then add Memtro to your client once. The Mollie 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 Mollie 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 Mollie MCP server?

No. It is Memtro's MCP server with Memtro's Mollie connector behind it: the connector reads Mollie through its API with the credentials you connect on Dashboard → Connections, and Mollie 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 Mollie?

Only when you ask, and only what it has been granted: create a customer record in Mollie; refund a payment, fully or partly, to the customer; cancel a refund that is still queued or pending; create a payment link to share with a payer; cancel a payment that is still open; cancel a customer's subscription so no further charges are taken; change a customer's name, email or locale; delete a customer, cancelling its mandates and subscriptions. 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.
