Brex + Memtro

Who spent what on which Brex card, and against which budget.

Connect Brex with a read-only user token and ask about card spend, individual expenses with their memos and receipts, budgets versus actual spend, and cash balances. Memtro summarises each day's card spend and flags large or out-of-policy expenses.

What you can do with Brex in Memtro

Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Brex tool, reads what it needs, and answers with the source cited.

01

Month-end review

Daily spend summaries with top merchants and categories are already in the graph, so finance can ask for the month's pattern and then drill into any day's expenses with brex_expenses.

02

Policy exceptions

An expense flagged out of policy, or any single purchase of 500 or more, becomes a memory naming the cardholder, merchant, budget and memo the hour it appears.

  • Card transactions by date, cardholder, merchant or amount
  • Expenses with memo, category, budget, approval and receipt status
  • Cards with limits and available spend
  • Budgets and spend limits against spend this period
  • People, departments and locations
  • Cash account balances and transactions

Ask it like this

Questions people ask once Brex is connected. In agent mode each one also checks the other systems that know about the same people, companies or identifiers.

  • ›What did we spend on software last month?
  • ›Which expenses are still missing receipts?
  • ›How much of the marketing budget is left this quarter?
  • ›Who holds a card over $5,000 a month?
  • ›Show me expenses flagged out of policy this week
  • ›What is the cash balance today?

Where it fits

Teams that get the most from Brex in Memtro, with the rest of their stack attached.

Better together

A record in Brex is rarely the whole story. Connect the systems that hold the rest and the agent cross-references them by default, then remembers what it learned so the next question starts further along.

Questions

Can Memtro change anything in Brex?
Not yet. Today every Brex tool reads, searches or lists. When the connector gains actions, each is marked, granted by name per team and used only when a person asks for exactly that, so nothing is created, sent, updated or deleted until you say so.
Who can use a Brex connection?
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Does Memtro store my Brex data?
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded. An hourly sync anchors recently changed Brex records into memory as entities.
How do I connect Brex?
API key. In Brex go to Developer → Settings and create a user token with read-only scopes.
