What the Brex MCP Server unlocks

The Brex MCP Server bridges standard large language models directly via the platform.brexapis.com to your startup's core spend engine. By delivering a single static User Token, you enable the most flexible financial assistant available.

What you can do

Agile Employee Onboarding — brex_create_user directly provisions employees with their associated hierarchical structure. Follow it up with brex_create_card to hand them digital spend capacity securely limited.
Accounting Snapshots — You don't need to load the Brex dash to trace down runaway expenses. Trigger brex_list_transactions to pull highly contextualized raw CSV data into your AI workspace.
Accounts Payable Controls — Draft and approve external entity vendors via brex_create_vendor and initiate routing payments brex_pay_vendor seamlessly, letting internal routing protocols map out the wires.

How it works

1. In your Brex settings, you can generate an immediate User Token (typically starting with user_token_).
2. This token natively identifies you and limits AI actions safely within your existing managerial permissions level.
3. Drop this into your client credentials and authorize AI access.

Who is this for?

Forward-Thinking CFOs / FinOps — Handle your routine accounting actions strictly through language.
Startups Scaling — Automatically loop AI agents to handle corporate card provisioning to cloud instances without manual checks.

Frequently asked questions about the Brex MCP Server

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.
