# Connect Vapi to Brex

When **New Assistant** fires in [Vapi](https://apiant.ai/connections/vapi), your agent runs **Update a Budget - “Brex Empower” Customers Only** in [Brex](https://apiant.ai/connections/brex). Describe the whole flow and it is built, tested on every scenario and kept running.

Vapi **3** triggers Vapi **21** actions Brex **27** actions

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want Vapi and Brex to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

### Cursor

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Questions

## Vapi and Brex, answered

###

### What can start an automation from Vapi?

Any of Vapi's 3 triggers in the catalog, including New Assistant, New Call and New File. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Brex when something happens in Vapi?

Any of Brex's 27 actions, including Create Department, Create Location, Create User and Create Vendor. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Brex to Vapi?

Brex has no triggers in the catalog today, so automations start in Vapi. If you need the other direction, ask: your agent reads Brex's API documentation and adds it.

###

### Do I have to build a connector for Vapi or Brex?

No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.

###

### Can my AI client use Vapi and Brex without building an automation?

Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.

###

### What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

###

### Is there a free plan?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
