• 01

  How secure is the connection to my Brex account?

  The MCP uses your existing Brex User Token. This means the AI can only perform actions that you already have permission to do within Brex.

• 02

  Do I need to manually approve every card I issue?

  The AI performs actions based on your existing managerial permissions. If your Brex role allows you to create cards, the AI can do it for you.

• 03

  Can I use this with any AI client?

  Yes, this MCP works with any client that supports the Model Context Protocol, such as Claude, Cursor, or Windsurf.

• 04

  What happens if I want to see the full transaction list?

  You can use the capability to sweep historical transactions, which your agent can then summarize or filter for you.

• 05

  Can I pay vendors directly through the AI?

  Yes, the MCP includes capabilities to create vendors and orchestrate payments through your Brex account.

• 06

  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.

• 07

  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.

• 08

  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.

• 09

  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.
