All 3 Brex skills

Each skill is one job. You ask in plain words and the agent loads the skill that matches, then follows its steps.

Use Brex with AI, safely

Connects your Brex account so an AI assistant can read your cards, spend limits, expenses and reimbursements. It confirms whose account it is reading, keeps card and money data read-only, and says plainly when something is blocked or missing.

Use it when

  • You have just connected Brex and want to know what it can show you
  • A question needs a colleague's details and you want the right person found first
  • You want spend answers without the assistant changing any card or expense

Tools it uses

  • get_user_myself
  • list_users_by_name_or_email
  • list_users
  • get_user_by_id
  • list_my_cards
  • get_card_by_id
  • list_my_limits
  • list_my_expenses
  • get_reimbursement_payout_date
  • get_expense_policy
Example

What's my remaining balance on my T&E spend limit, and which of my recent expenses are in it?

Showing this for Priya Shah. Your T&E limit has $1,240 remaining of $3,000 for the current period. Your last 12 expenses total $1,760, and 9 of them fall in the T&E category. I read the first page only, so ask if you want the rest. I can't change the limit or any expense here; that happens in the Brex dashboard.

Audit Brex card spend for a period

Reviews card and expense activity for a chosen period and ranks unusual, unreceipted or policy-breaking spend by risk. It only reads data and never changes cards, limits or expenses.

Use it when

  • Before month-end close, when you want to catch unreceipted or split charges
  • When a manager asks what the team spent on cards last quarter
  • When you suspect duplicate or policy-breaking spend and need a ranked list

Tools it uses

  • get_user_myself
  • list_my_cards
  • list_users_by_name_or_email
  • list_users
  • get_user_by_id
  • get_card_by_id
  • list_my_expenses
  • get_expense_policy
Example

Audit card spend for the team last month and show me the high-risk items first.

Scope: last month, whole company, viewed as card admin. 38 cards and 412 card expenses reviewed. Flagged: 3 high, 9 medium, 14 low. The top high item is three 480 charges to one merchant on the 14th, each just under the 500 approval line, which looks like splitting and needs an explanation from the cardholder.

Check your Brex spend limits and reimbursement payouts

Ask how much you have left on a spend limit, when it resets, and when an approved reimbursement is expected to pay out. It reads the figures and states what it cannot confirm.

Use it when

  • You want to know how much you can still spend this period
  • You are close to a limit and need to plan a purchase
  • You are waiting on a reimbursement and want the expected payout date

Tools it uses

  • get_user_myself
  • list_users_by_name_or_email
  • get_user_by_id
  • list_users
  • list_my_limits
  • get_reimbursement_payout_date
  • get_expense_policy
Example

How much do I have left on my T&E limit, and when does it reset?

You have $1,200 left of your $5,000 T&E limit for this month, resetting on the 1st. That means you have spent $3,800 so far, so you are at 76% of the ceiling. Your approved reimbursement for the client dinner has an expected payout date of the 14th, though bank processing can add a day or two.

How Brex skills work

  1. Connect Brex

    The Brex MCP server gives the agent its tools.

  2. Ask in plain words

    “Audit card spend for the team last month and show me the high-risk items first.” Each SKILL.md says when it applies, so only the one that fits is loaded.

  3. Approve any change

    The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install Brex skills

In RevampKey the skills install themselves when you connect Brex. In other tools each skill is one folder with a SKILL.md file, and you also need the Brex MCP server connected there.

About 1 minute · nothing to copy

  1. Download RevampKey for Mac, Windows or Linux and sign in.

  2. Open Connectors and connect Brex. All 3 skills come with it and stay up to date; they go away when you remove the connector.

  3. Ask in plain language, for example “Audit card spend for the team last month and show me the high-risk items first.”

Brex skills FAQ

What is a Brex agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Brex skill describes one job, which Brex tools to use in which order, what to check first and when to stop and ask you.

Do the Brex skills change anything on their own?

3 of the 3 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Brex.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Brex; elsewhere you copy the folders into your project or skills directory.

Do I need the Brex MCP server too?

Yes. The skills tell the agent how to do the work; the Brex MCP server gives it the tools to do it. The Brex MCP setup guide covers every client.
