# Connect Sender to MailerCheck

When **New Group** fires in [Sender](https://apiant.ai/connections/sender), your agent runs **Verify an Email Address** in [MailerCheck](https://apiant.ai/connections/mailercheck). Describe the whole flow and it is built, tested on every scenario and kept running.

Sender **4** triggers Sender **10** actions MailerCheck **10** actions

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

## What do you want Sender and MailerCheck 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

### 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.

###

### Can my AI client use Sender and MailerCheck 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.
