Before you connect

Questions about Brex.

The practical details behind the request, access and result.

Can the Brex MCP help me manage my company cards?

Yes, it lets your agent issue new virtual cards, list all active cards, and check spending limits without you having to log in.

How does the Brex MCP handle new employee onboarding?

It can automatically create user profiles and assign them to the correct hierarchy, then immediately issue their corporate cards.

Can I use the Brex MCP to see my transaction history?

Yes, your agent can pull historical card and account transactions into your chat, making it easy to audit spend on the fly.

Does the Brex MCP support vendor payments?

Yes, you can create new vendors and initiate payments through your agent, which handles the routing based on your internal protocols.

Can I check my cash balance with the Brex MCP?

Your agent can pull the main cash balance for your accounts instantly, giving you a quick look at your liquidity.

Is the Brex MCP good for startups?

It's ideal for startups that need to scale their corporate card programs and manage spend quickly as they grow.

Can the agent truly issue a real, functioning corporate card?

Yes! The brex_create_card logic specifically maps to creating a virtual limit card. By default, it operates completely valid via Visa/Mastercard configurations matching Brex internals. The agent handles setting its name and tying it strictly to the user id.

What acts as the final authentication key for Brex?

You only need a User Token. Brex explicitly supports personal workflow automation using user_tokens which perfectly mimic your permissions. It typically begins literally with the string user_token_ followed by hashes.

Will vendor payments via AI require external 2FA from my side?

To enforce safety in the integration, the approval_type parameter when sending vendor money defaults to 'MANUAL'. This means the AI structures all the math, formatting, routing inputs perfectly but leaves the final 'Accept' button queued on your dashboard.

How can I see my user lists across Brex?

Run a request on brex_list_users. The AI will natively stream the company's organizational tree mapping the emails to Brex UUIDs required for triggering corporate card injections.
