## Description

Searches settled card transactions across all card accounts by merchant, amount, date, or cardholder, and returns each transaction's `expense_id`, the handle Brex uses for the matching expense and its receipt. Non-admin users only ever see their own purchases, refunds, and chargebacks. Unlike **List Transactions for Primary Card Account**, which returns the same transactions unfiltered, this action applies filters and expands `expense_id`. [See the documentation](https://developer.brex.com/openapi/transactions_api/transactions/listprimarycardtransactions)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `postedAtStart` | `string` | No | Return only transactions posted on or after this date-time, in RFC 3339 notation, e.g. 2022-12-12T23:59:59.999Z. Brex can post transactions with a lag, so when polling repeatedly, overlap this with your previous window by a day or more and de-duplicate results by transaction id rather than advancing it to the exact end of the last poll. |
| `postedAtEnd` | `string` | No | Only return transactions posted on or before this date-time, in RFC 3339 format, e.g. 2024-01-31T23:59:59.999Z. Brex has no server-side end date, so this is applied after fetching. |
| `userIds` | `string[]` | No | Only return transactions made by these people. Use List Users to find a user ID by email address. |
| `merchantQuery` | `string` | No | Case-insensitive substring match on the merchant descriptor, e.g. amazon matches AMAZON WEB SERVICES. Brex has no server-side merchant filter, so this is applied after fetching. |
| `minAmount` | `integer` | No | Only return records of at least this amount, in the currency's smallest denomination — 700 is $7.00 in USD. Applied after fetching, like Merchant. |
| `maxAmount` | `integer` | No | Only return records of at most this amount, in the currency's smallest denomination — 700 is $7.00 in USD. Applied after fetching, like Merchant. |
| `maxResults` | `integer` | No | The maximum number of records to return, from 1 to 2000. Defaults to 100. |

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(

const mcp = new Client({ name: "my-agent", version: "1.0.0" })
await mcp.connect(transport)

const { tools } = await mcp.listTools()

// listTools() hands your model this tool's input schema, so it can
// fill the arguments itself:
const result = await mcp.callTool({

  arguments: {
    postedAtStart: "Posted At Start",
    postedAtEnd: "Posted At End",
  },
