Ask your coding agent to use Veracity Pay. Through MCP it asks which payment partners to emulate, registers the account and e-mails you the keys – without ever seeing a secret.
8 payment partners: Stripe, Nets Easy, Adyen, Kustom, Swish, Svea, Walley and Qliro. Free for now.
claude mcp add --transport http veracity-pay https://pay.veracity.se/mcp“I want us to use Veracity Pay to emulate payments in this project.”
Merchant ID, keys and ready commands arrive in your inbox. The agent sees no secrets.
The customer enters an e-mail, picks card, Swish, invoice or bank transfer and approves with the code. In the test panel you choose whether the payment is approved, declined, pending or needs 3-D Secure.
