Brex MCP integration
Finds charges by description or amount, issues and limits cards, matches receipts to expenses, and subscribes to Brex events.
84actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Search transactions by description
Ayro finds and filters card transactions by description text. Support teams quickly locate specific charges to resolve customer inquiries about spending.
Set user limit
Ayro updates the monthly spending limit for a Brex user instantly. Managers adjust caps mid-conversation when customers need temporary changes.
Update card status
Ayro locks, unlocks, or terminates a Brex card without delay. Support resolves frozen-card issues or disables compromised cards in seconds.
How businesses use Brex + Ayro
Each card is one request a support team gets, and the Brex actions Ayro runs to close it.
Explain a charge from how someone described it
Ayro finds the transaction from a merchant name or a rough amount, opens it for the full detail, and reports the card and account it landed on, so nobody has to scroll a statement.
Search Transactions by DescriptionGet Transactions by Amount RangeGet Transaction by IDIssue a card and cap what it can do
Ayro creates the card for a specific purpose, sets the limits it has to stay inside, and changes its status the moment the spend is finished or something looks wrong.
Create CardUpdate Card LimitsUpdate Card StatusClose an expense out against its receipt
Ayro pulls the open expense, uploads the receipt the employee just sent through, and matches it to the transaction so the record clears without a chase email.

Ayro registers a webhook subscription, reports what is already subscribed, and adds an endpoint to a webhook group so one event reaches every system that needs it.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Ayro reads the Brex actions it has and picks the ones a request needs.
Connect Brex
Authorize the Brex account your team already uses — one consent screen, no API keys, no mapping tables. Ayro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Ayro maps it to the Brex actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

FAQ
Everything else about Brex
Setup, permissions, and the limits of what Ayro can do inside Brex.
Only if you enable the one action that returns it. Get Card Number exposes the number for a card, while Get Card Details, List Cards, and Update Card Status all work from metadata and state alone. For a connection that touches customer or employee conversations, leave Get Card Number out of the enabled set.
