# setup_payment_method

> Get a secure checkout link so the user can save a card for future use.

Creates a setup session so the user can save a payment method for future card creation. Once saved, that payment method is used automatically when new cards are created with [create\_card](/companies/mcp/tools/create_card).

## Parameters

This tool takes no parameters.

## Returns

A secure Stripe checkout URL and its session ID. The user must open the URL to save their card details; once completed, the saved card funds future transactions automatically. To see what is already saved, use [list\_payment\_methods](/companies/mcp/tools/list_payment_methods).

## Example

```json theme={null}
{ "name": "setup_payment_method", "arguments": {} }
```
