## Description

Updates the spend limit on a vendor card (`limit_type: CARD`). This sends a complete `spend_controls` object, so treat it as a replacement: supply every spend control you want the card to keep, because Brex does not document whether omitted fields are preserved or cleared. Corporate cards draw on their cardholder's limit instead — use **Set Limit for User** for those. [See the documentation](https://developer.brex.com/openapi/team_api/cards/updatecard)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `cardId` | `string` | Yes | The unique ID of the card. Use List Cards to find a card ID by cardholder, name, or last four digits. |
| `amount` | `integer` | Yes | The new spend limit, in the currency's smallest denomination — 700 is $7.00 in USD. |
| `currency` | `string` | No | The currency of the limit, in ISO 4217 format, e.g. USD. Defaults to USD when omitted, so set this explicitly for a card denominated in any other currency. |
| `spendDuration` | `string` | Yes | How often the limit refreshes: MONTHLY, QUARTERLY, or YEARLY to refresh on that cadence, or ONE_TIME for a limit that never refreshes. Sent on every update, so set it to the cadence the card should have from now on — use Get Card to read the card's current duration first if you only mean to change the amount. |
| `reason` | `string` | No | A free-text note explaining the new limit. Sent on every update, so re-supply the card's existing note if you want to keep it — use Get Card to read it first. |
| `lockAfterDate` | `string` | No | Freeze the card automatically after this UTC date, in yyyy-mm-dd format. Sent on every update, so re-supply the card's existing lock date if you want to keep it — use Get Card to read it first. |

## Run it

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

  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(

    },
  },
)

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-update-card-limit",
  arguments: {
    cardId: "Card ID",
    amount: 10,
  },
})
```
