allow_card_merchant

Connect to https://mcp.agentcard.sh/mcp with the user’s connection token (or a buy_token for org-owned accounts).

What it does

Remember a merchant so the next charge there passes the card’s category and merchant rules. One tool call: no form, no support ticket, no new card, and the merchant stays allowed on that card from then on. The loop is three lines: the purchase is refused and the agent is told why; the agent calls this tool naming the merchant; the card resumes and the retry goes through. The pause or watch notice names the card id and the merchant pattern to pass. Pass card_id to remember it on that card, the default. The rest of the preset stays in force: spend, place, currency, time, and only_from rules still apply. The pattern is a case-insensitive substring of the merchant descriptor. If a multi-use card was paused after settlement, remember the merchant, call resume_card, then retry.
