Human step
Confirmed
Confirmed means the vendor documents it (linked). It doesn't mean IonBin has tested it. AI-platform and human steps need no source.
Human approval
You decide what is out of policy and approve the memo.
Watch out for
Keep the human approval step: You decide what is out of policy and approve the memo.
Starter prompt
Goal: Spot unusual spend quickly and document it for the month-end close. Tools involved: Brex, Brex (alternative), Julius AI. Your part: lists expenses for claude through the brex mcp server (beta); drafts the spend memo from the flagged list. Work step by step, show me each draft or proposed change, and wait for my approval before anything is sent, published, signed, filed or changed in a live system.

What we checked
Brex CSV. In the Brex dashboard, Expenses lets you choose columns with the gear icon, apply filters, save the view, and download the table in the format you pick. Account admins, card admins and bookkeepers can download everyone’s card expenses; other roles get their own.
Brex MCP (beta) lets AI assistants look up expenses, users, cards, banking transactions and bills. An account or card admin accepts the Developer API agreement, then turns on Brex in AI assistants under beta features. Each user connects with their own permissions. Brex recommends turning on human confirmation, and its tools may change while it’s in beta.
Julius AI has no MCP server, so you upload the CSV yourself.
Set it up
Save a Brex Expenses view with date, merchant, category, amount, cardholder and memo columns.
Download the month as a CSV and upload it to Julius.
Ask Julius for outliers by person and category, and for anything that breaks your written policy.
Have Claude draft the memo from the flagged list. Follow up with people before you call anything out of policy.
