## Description

Lists the cards in the Brex account, each with its status, last four digits, cardholder, and spend limit. Filter by cardholder (`userId`) or status (`ACTIVE`, `SHIPPED`, `LOCKED`, `TERMINATED`) — status has no server-side filter, so it's applied after fetching, which can leave results truncated before every match is scanned; raise `maxResults` (default `100`) or drop the status filter if that happens. This is how you find the card ID that **Get Card**, **Freeze Card**, **Cancel Card**, and **Update Card Limit** require. [See the documentation](https://developer.brex.com/openapi/team_api/cards/listcardsbyuserid)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `userId` | `string` | No | Return only cards owned by this person, as a Brex user ID, e.g. cuuser_ckze72soa117f01pkmf1wcpl3. Omit to list every card in the account. Use List Users to find a user ID by email address. |
| `status` | `string` | No | Only return cards with this status. Brex has no server-side status filter, so results are filtered after being fetched. |
| `maxResults` | `integer` | No | The maximum number of records to return, from 1 to 2000. Defaults to 100. |

## Run it

**MCP**

```ts
import { Client } from "@modelcontextprotocol/sdk/client/index.js"
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js"
import { PipedreamClient } from "@pipedream/sdk"

const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const accessToken = await pd.rawAccessToken

const transport = new StreamableHTTPClientTransport(
  new URL("https://remote.mcp.pipedream.net/v3"),
  {
    requestInit: {
      headers: {
        Authorization: `Bearer ${accessToken}`,
        "x-pd-project-id": process.env.PIPEDREAM_PROJECT_ID!,
        "x-pd-environment": "production",
        "x-pd-external-user-id": "{external_user_id}", // any stable ID for this user in your system
        "x-pd-app-slug": "brex",
      },
    },
  },
)

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({
  name: "brex-list-cards",
  arguments: {
    userId: "Cardholder",
    status: "Status",
  },
})
```

**TypeScript**

  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "brex-list-cards",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    brex: { authProvisionId: "apn_xxxxxxx" },
