mint_buy_token - Agentcard

Connect to https://mcp.agentcard.sh/mcp with your organization credential (client_id + client_secret, or the org access token).

What it does

Create a scoped 30-day token that lets this cardholder’s agent act as THAT ONE USER — add balance to their wallet, complete verification, and shop through the buy agent — with no browser OAuth. The pattern for messaging surfaces (iMessage, SMS, WhatsApp): store the token keyed by your user and reuse it; create a fresh one any time.
