Tools that your AI agent can use through this MCP server to interact with Brex

Set Limit for User

Sets the monthly limit for a user. See the docs here.

Search Card Transactions

Searches settled card transactions across every card account by merchant, amount, date, or cardholder, and returns each transaction's expense_id, the handle Brex uses for the matching expense and its receipt. Unlike List Transactions for Primary Card Account, this filters and expands. See the documentation

List Users

Lists the people in the Brex account with their ID, name, email, status, manager, department, and location. Filter to one person with email, or set includeLimits to include each person's monthly spend limit. Results are capped at maxResults (default 100) — check $summary for a truncation notice and raise maxResults or add the email filter if it's truncated. This is how you turn an email address into the user ID that Get User, Get User Limit, and Set Limit for User require. See the documentation

List Transactions for Selected Cash Account

Lists all transactions for the specified cash account. See the docs here.

List Transactions for Primary Card Account

Lists all settled transactions for the primary card account. See the docs here.

List Cash Accounts

Lists the Brex cash accounts with their balances, account and routing numbers, and which one is primary. Results are capped at maxResults (default 100) — check $summary for a truncation notice and raise maxResults if it's truncated. This is how you find the account ID that List Transactions for Selected Cash Account requires. See the documentation

Invite User

Invites a new user as an employee. See the docs here.

Get User

Retrieves one person in the Brex account, including their status, manager, department, location, and title. Use List Users to find a user ID by email address. See the documentation

Get User Limit

Retrieves a person's monthly spend limit and how much of it is still available. Change it with Set Limit for User. See the documentation

Create Card

Creates a new card. See the docs here.
