Who it is for
Finance and accounting teams running a Brex programme, plus employees squaring away their own receipts and memos.
Brex
Company spend and expense lookups for finance teams
Overview
What Brex does
Brex opens company card and expense records to questions from finance staff and from employees checking their own spend. Lookups cover expenses, cards, users, bills, vendors, spending limits, and accounting records.
The app also writes. Receipts can be attached from HTTPS URLs, memos and attendee lists can be edited, card expenses can be assigned to a limit, and expense data can be exported. Analysis of spending patterns sits alongside the record keeping, and product feedback can be sent from the same place.
The example in the listing is the everyday kind: totalling what was spent with a single airline over the past year.
What stands out
It covers the tidying work as well as the reporting, including receipt attachment and reassigning card expenses to limits.

Where Brex is listed
Brex ships this on both marketplaces: Brex is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.
Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing
In the Claude connectors directory
Brex publishes 10 tools to Claude. That is a mid-sized surface: 45% of the 1,253 Claude-listed connectors expose fewer.
The median Claude-listed connector filed under Finance publishes 12, so this one sits 2 tools below its bucket's median, 87th of 159.
It falls in the 7-10 tools band, which holds 14.6% of the Claude directory.
Brex publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.
Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.
