setup_payment_method - Agentcard

Connect to https://mcp.agentcard.sh/mcp with the user’s connection token (or a buy_token for org-owned accounts).

What it does

Save a payment method used ONLY to pay for flight bookings (the fare is charged to it via a hold at booking; no virtual card is created for flights). It does NOT fund cards or the cash balance — cards are funded from the balance (see add_funds). Returns a secure checkout URL the user must open to save their card details.

Inputs

None.

Returns

Field	Type	Description
`message` (required)	string	Human-readable summary of the result.
`checkoutUrl`	string	Secure Stripe checkout URL the user must open to save their payment method.
`stripeSessionId`	string	Identifier of the Stripe Checkout session created for the setup.
