Wallet

Security and privacy

The boundaries between your Wallet account, agent, and payment method.

Wallet keeps the agent’s authority narrow: the agent can propose actions, while you approve the authorization and Wallet protects the payment-method details.

Trust boundaries

YouSign in, review the request, approve or decline an authorization, and manage cards and profile data.
Your agentUses the MCP tools for the connected account. It cannot approve its own authorization or view card details.
YunoHosts card enrollment and retains sensitive card information.
WalletStores safe payment references, evaluates purchase intents, and issues the current temporary mock credentials.

Local development

Only connect trusted MCP clients to a local Wallet server. Do not paste a card number, CVC, PIN, password, Wallet session token, or API secret into an agent conversation.

Release limitation

Temporary mock cards only

This version does not charge cards or contact merchants, processors, or payment networks. Its synthetic `000000` credentials are non-chargeable, are not derived from Yuno Vault cards, and do not work at real or sandbox processors.
