Preview · Built on MCP

Let your AI assistant buy for you, within limits you approve.

Yuno Wallet connects assistants to your payment cards through the Model Context Protocol. The assistant asks; you approve the merchant, the amount and how long it lasts. It never sees your card number.

Sign in with a one-time code by email or text. No password.

Illustration of an approval request: the merchant, per-purchase limit, budget and expiry are shown before you decline or authorize.

Works over the open MCP standard

Any MCP client that supports OAuth sign-in can connect. The wallet shows each assistant by name, and marks connections that come from chatgpt.com, claude.ai, cursor.com or grok.com as verified.

How it works

  1. Connect your assistant

    Add the wallet as an MCP connector and approve the connection once. You can disconnect it from Agents whenever you like.

  2. Approve exactly what it asks

    When it wants to buy, it sends a request: the merchant, the most it may spend per purchase, a budget and an expiry. Nothing is allowed until you approve.

  3. It pays inside those limits

    Each purchase gets its own credential, checked against your limits first: a Visa network credential issued against your card token, or a synthetic mock card.

Control stays with you

  • Limits you can read

    Per purchase, budget, merchants, categories and expiry, in plain words, before you say yes.

  • Your card number stays out of the chat

    Cards go through Yuno’s secure form into Yuno Vault. An agent never sees the number or security code.

  • Spending you can follow

    Each authorization shows how much of its budget is used, and the activity timeline records every credential and outcome.

  • Stop anything, any time

    Revoke an authorization or disconnect an assistant. New credentials are blocked immediately.

Security by design

The wallet is built so that an assistant can act for you without ever holding what would let it act as you.

  • Passwordless sign-in: a six-digit code sent to your email or phone.
  • Your access token stays on the server. It never reaches the browser or the assistant.
  • Card details are typed into Yuno’s secure fields. The wallet keeps only a vault reference and safe details such as the brand and last four digits.
  • With Visa Intelligent Commerce, each purchase instruction is confirmed with a Visa Payment Passkey on your device.
