How to Use the Brex MCP in Cursor

Q: How do I install the Brex MCP Server in Cursor?

Create an mcp.json file in your project's .cursor directory or your global home folder. Add the server details, which registers the MCP Server locally, and the agent will immediately detect the financial tools.

Q: Can I manage my vendor list inside Cursor?

Yes, you can use brexcreatevendor to add new payees to your account directly from your editor. The agent can read a local CSV of contractors and register them in your corporate dashboard automatically.

Generate code that interacts with your Brex account directly inside the Cursor agent.

Test integrations with live Brex data in Cursor

The `brex_list_transactions` tool pulls actual historical card transactions directly into your Cursor editor. This lets your agent write and test parsing scripts using real financial payloads instead of fragile mock data. Because Cursor runs this MCP Server in Agent mode, the AI reads the structural layout of your real transaction history to generate highly accurate code. You write integration tests that work on the first run.

Execute vendor payments using Cursor Agent

The `brex_pay_vendor` tool lets your agent initiate AP payments directly from your development workspace. You can draft, test, and execute payment scripts without jumping back and forth to your browser. Cursor coordinates with `brex_list_vendors` to verify the recipient exists before executing the payment. This prevents routing errors and ensures your automated payment scripts target the correct corporate accounts.

Audit issued cards inside the Cursor IDE

The `brex_list_cards` tool displays all active corporate cards directly in your sidebar or terminal window. You can quickly cross-reference card IDs with your local environment variables while writing deployment scripts. If a subscription card is missing, use `brex_create_card` to spin up a new virtual card without pausing your coding session. The agent inserts the new card details directly into your configuration files.

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
