Brex MCP server
The Brex MCP server lets your AI agent work with Brex from Claude, Cursor, or ChatGPT. It's official, made by Brex, runs online, so you add one address, and you sign in with your account.
Add it to your agent
In Claude, open Settings, then Connectors, select Add custom connector, and paste this address.
https://api.brex.com/mcpBefore you connect it
An MCP server lets your agent read and change what you connect it to in Brex. Connect a test account or a test project first, and check what your agent can do before you give it your real data.
