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

## What do you want MailerSend and Google Cloud Pubsub 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, 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

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

### 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.

###

### What can start an automation from MailerSend?

Any of MailerSend's 11 triggers in the catalog, including Email Is Clicked Through, Email Is Delivered, Email Is Hard Bounced and Email Is Opened. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Google Cloud Pubsub when something happens in MailerSend?

###

### Can it also run from Google Cloud Pubsub to MailerSend?

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

###

### Do I have to build a connector for MailerSend or Google Cloud Pubsub?

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 MailerSend and Google Cloud Pubsub 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.
