buy_view_cart

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

Not in the default tools/list. It is still callable by exact name, and appears when the client sends the x-expert-tools: 1 header.

What it does

View the current cart (items + totals) at a linked merchant. Use this to build the itemized confirmation before checkout. If the user wants to TIP, pass that same tip as tip_cents here so the total you show them (cart + tip) is the exact amount checkout will charge — then pass the SAME tip_cents and that shown total (as expected_total_cents) to buy_checkout.

Inputs

Field	Type	Description
`merchant` (required)	string
`tip_cents`	number	optional tip (cents) the user asked for, to include in the shown total. Pass the SAME value to buy_checkout. Omit if no tip.

Returns

None.
