create_payment_link

Create a payment link in EUR for Belgium via Mollie. Buyer pays with Bancontact (the rail Belgian buyers actually use), cards, and other methods enabled on the Mollie account. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-mollie-api-key; free test credentials from my.mollie.com never move real money). Money always flows buyer→Mollie→merchant; this service never touches funds.

Parameters4

amount_eur	number	required	Amount in EUR (decimals allowed), e.g. 10. Minimum 1.
description	string	required	What this payment is for (shown to the buyer, ≤200 chars)
customer_email	string	optional	Optional buyer email.
success_url	string	optional	Optional https URL to send the buyer to after payment.

      "type": "number",
      "minimum": 1,

    }
  },
  "required": [
    "amount_eur",
    "description"
  ]
}

query_payment_status

Check whether a Belgium payment (created by create_payment_link) has been paid. Queries Mollie directly — pull-based, no webhook needed. paid=true when status is PAID.

Parameters1

payment_id

string

required

The payment_id (tr_...) returned by create_payment_link

Raw schema

{
  "type": "object",
  "properties": {
    "payment_id": {
      "type": "string",
      "description": "The payment_id (tr_...) returned by create_payment_link"
    }
  },
  "required": [
    "payment_id"
  ]
}

refund_payment

Refund a paid payment (created by create_payment_link). Full refund by default; pass amount for a partial refund where supported. Refunds respect the same owner policy guardrails (x-agentpay-max-amount) as payments — the amount is checked before anything is sent to the gateway.

Parameters2

payment_id	string	required	The payment_id of the paid payment (same id used by query_payment_status)
amount	number	optional	Optional partial-refund amount in the local currency major unit. Omit for a full refund.

Raw schema

{
  "type": "object",
  "properties": {
    "payment_id": {
      "type": "string",
      "description": "The payment_id of the paid payment (same id used by query_payment_status)"
    },
    "amount": {
      "type": "number",
      "description": "Optional partial-refund amount in the local currency major unit. Omit for a full refund."
    }
  },
  "required": [
    "payment_id"
  ]
}

create_subscription_link

Create a recurring subscription in EUR for Belgium via Mollie (Bancontact / SEPA Direct Debit, cards, PayPal — whatever recurring methods are enabled on the Mollie account). Mollie recurring is a two-step, honest flow (there is no single call that returns a ready subscription, because the buyer must authorize a mandate first): this tool creates a Mollie customer and a FIRST payment (sequenceType=first) and returns a hosted checkout URL. The buyer opens it once and pays — that first payment IS the first billing period AND authorizes the mandate. Then call activate_subscription with the returned customer_id and payment_id to start the recurring plan for the remaining periods. amount_eur is charged PER billing period. Requires x-mollie-api-key. Respects the same owner policy guardrails (x-agentpay-max-amount / x-agentpay-approval-above) as payments — the per-period amount is checked before anything is created. Money always flows buyer→Mollie→merchant; this service never touches funds.

Parameters8

amount_eur	number	required	Amount charged PER billing period, in EUR (decimals allowed), e.g. 9.99. Minimum 1.
description	string	required	What the subscription is for (shown to the buyer; also used as the Mollie subscription description, ≤200 chars).
period	string	optional	Billing period. Default "monthly".
interval	integer	optional	Charge every N periods (period=monthly, interval=3 = every 3 months). Default 1. (Yearly is billed as 12-month intervals; interval multiplies that.)
total_count	integer	optional	Total number of billing periods to charge, INCLUDING the first payment (e.g. 12 monthly = one year). Omit for an open-ended subscription that renews until cancelled.
customer_name	string	optional	Optional buyer name (stored on the Mollie customer).
customer_email	string	optional	Optional buyer email (Mollie sends receipts there).
success_url	string	optional	Optional https URL to send the buyer to after they authorize/pay the first payment.

    "amount_eur",
    "description"
  ]
}

activate_subscription

Second step of the Mollie subscription flow. After the buyer has opened the create_subscription_link URL and paid the first payment (which authorizes the mandate), call this with the customer_id and payment_id that create_subscription_link returned. If the mandate is now valid it creates the recurring subscription (for the periods after the first payment) and returns subscription_id (sub_...). If the buyer has NOT finished authorizing yet, it does NOT error — it returns activated=false with a readable mandate_status so you can keep polling (call query_subscription, wait ~20s, then call activate_subscription again). Idempotent: if the subscription already exists it returns the existing one. The plan parameters (amount / period / interval / total_count) were stored on the first payment, so you do not re-supply them here.

Parameters2

customer_id	string	required	The customer_id (cst_...) returned by create_subscription_link.
payment_id	string	required	The payment_id (tr_...) returned by create_subscription_link (it carries the stored plan parameters).

Raw schema

  "type": "object",
  "properties": {
    "customer_id": {
      "type": "string",

    },
    "payment_id": {
      "type": "string",
      "description": "The payment_id (tr_...) returned by create_subscription_link (it carries the stored plan parameters)."
    }
  },
  "required": [
    "customer_id",
    "payment_id"
  ]
}

query_subscription

Check a Belgium subscription. Pass customer_id alone for an overview: status AWAITING_AUTHORIZATION (buyer has not authorized the mandate yet — keep polling / call activate_subscription), MANDATE_VALID (buyer authorized; call activate_subscription now to start the recurring plan), or ACTIVE (a subscription is running; subscription_id is returned). Pass customer_id AND subscription_id (sub_...) to check one subscription directly: ACTIVE | PENDING | CANCELED | SUSPENDED | COMPLETED, with next_charge_date. Pull-based — no webhook needed.

Parameters2

customer_id	string	required	The customer_id (cst_...) returned by create_subscription_link.
subscription_id	string	optional	Optional subscription_id (sub_...) from activate_subscription to check one subscription directly. Omit for a mandate + subscription overview.

  "type": "object",

    }
  },
  "required": [
    "customer_id"
  ]
}

cancel_subscription

Cancel a Belgium subscription so it stops charging. Pass the customer_id (cst_...) and the subscription_id (sub_...) from activate_subscription / query_subscription. Mollie cancellation is immediate — no further billing periods are charged. (If the buyer never authorized the mandate, there is nothing to cancel; just let the first payment expire.)

Parameters2

customer_id	string	required	The customer_id (cst_...) the subscription belongs to.
subscription_id	string	required	The subscription_id (sub_...) to cancel — get it from activate_subscription or query_subscription.

Belgium Payments MCP — let AI agents accept payments in Belgium

Use it in 60 seconds

Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):

json

{
  "mcpServers": {
    "belgium-payments": {
      "type": "http",
      "url": "https://mcp-be.wishpool.app/mcp"
    }
  }
}

Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.

Or run it yourself

Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:

bash

git clone https://github.com/junter1989k-ai/belgium-payments-mcp && cd belgium-payments-mcp && npx vercel --prod

Tool	What it does
`create_payment_link`	Create a EUR hosted-checkout link.
`query_payment_status`	Pull-based status check; `paid=true` when PAID.

Develop
