## What do you want MailCheck.ai and Refiner 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.

Any of MailCheck.ai's 4 triggers in the catalog, including Domain added to blocklist (instant), Domain flagged as relay (instant), Domain flagged as spam (instant) and Domain unflagged as spam (instant). Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Refiner when something happens in MailCheck.ai?

###

### Can it also run from Refiner to MailCheck.ai?

###

### Do I have to build a connector for MailCheck.ai or Refiner?

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 MailCheck.ai and Refiner without building an automation?

###

### 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.
