# buy_select_store

> Scope subsequent searches and the cart to one store within a multi-store merchant (DoorDash).

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

**Behavior:** idempotent.

<Note>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.</Note>

## What it does

Scope subsequent searches and the cart to one store within a multi-store merchant (DoorDash). Not needed for the retail merchant (amazon, walmart): pass the fixed store\_id straight to buy\_search\_products instead.

## Inputs

| Field                   | Type   | Description |
| ----------------------- | ------ | ----------- |
| `merchant` *(required)* | string |             |
| `store_id` *(required)* | string |             |

## Returns

None.
