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

## What do you want Beehiiv 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)

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

Questions

## Beehiiv and Brex, answered

###

### What can start an automation from Beehiiv?

Any of Beehiiv's 8 triggers in the catalog, including New subscriber to publication, New unsubscriber to publication, List automations and List newsletter lists. Describe the moment in plain language and your agent picks the right one.

###

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

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 Beehiiv?

Brex has no triggers in the catalog today, so automations start in Beehiiv. 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 Beehiiv 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 Beehiiv 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.
