How to Use the Brex MCP in Cline

Q: Can Cline write code that interacts with my Brex account?

Yes, Cline uses tools like brexlistcards to fetch live data, then writes TypeScript or Python code to process that data in your local project workspace. It tests the code against your actual account response to verify it works.

Q: How does Cline handle payment errors when using Brex tools?

When a tool like brexpayvendor fails due to insufficient funds or invalid vendor details, Cline reads the error payload. It then adjusts the payment parameters or checks your balance with brexgetbalance to fix the issue.

Let Cline build your internal financial dashboards and manage Brex virtual cards directly inside your VS Code workspace.

Issue Brex Cards Automatically inside Cline

The `brex_create_card` tool lets Cline generate virtual corporate cards on demand during your coding sessions. If you are writing a script that requires a dedicated subscription card, Cline executes this tool to secure the credentials. Cline doesn't just call the tool; it writes the card details directly into your local configuration file or environment variables. It then runs `brex_list_cards` to make sure the card is active and ready for your code to use.

Build Financial Dashboards with the Brex MCP Server

The `brex_get_balance` tool retrieves your current corporate cash balances so Cline can populate local dashboard components. You can tell Cline to build an internal status page, and it will fetch the live balance and write the React code to display it. It also runs `brex_list_transactions` to fetch recent transaction histories, writing test suites to parse the data correctly. This gives you a fully functional, live-tested financial component in minutes.

Manage and Pay Vendors in VS Code

The `brex_pay_vendor` tool processes payments to saved suppliers without you leaving VS Code. Cline reads your local invoice files, matches them with active vendors, and initiates the payment. If the vendor is new, Cline uses `brex_create_vendor` to register them first. It then runs `brex_list_vendors` to verify the registration before executing the payment.
