How do I connect Brex to Operator?

You authorize Brex once from your Operator dashboard. Operator holds the connection and refreshes the access token for you, so your agent keeps working with Brex without you signing in again.

Can my agent handle records and reporting in Brex?

Yes. It can create and update records, pull figures, and read a summary back to you in plain language. People use it to log transactions, check a balance, or answer a question about Brex data instead of building the report by hand.

Do I need to write code or manage Brex API keys?

No code and no API keys. You authorize Brex through a normal sign in and Operator handles the connection, so there is nothing to wire up or host.

Can my agent use Brex together with my other apps?

Yes. The same agent reaches every app you connect, so it can move between Brex and tools like Stripe, Coupa, Zoho books in one job, reading from one and acting in another without you wiring anything between them.

Automate Brex with AI

Operator puts an OpenClaw agent in front of Brex. You describe the job from Telegram or Discord and it handles the rest inside Brex, picking the right calls from the 84 Brex actions and checking its own work as it goes.

Your agent reaches Brex directly or through connectors like Composio MCP and Pipedream MCP, which handle the sign in and token refresh for you, so there is nothing to wire up and no API keys to paste.
