## What do you want Pennylane and Mailopost 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

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.

Questions

## Pennylane and Mailopost, answered

###

### What can start an automation from Pennylane?

Any of Pennylane's 5 triggers in the catalog, including New Billing Subscription V2, New Customer Invoice V2, New Customer V2 and New Product V2. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Mailopost when something happens in Pennylane?

Any of Mailopost's 18 actions, including Send campaign, Update list, Update recipient and Update template. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Mailopost to Pennylane?

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

###

### Do I have to build a connector for Pennylane or Mailopost?

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 Pennylane and Mailopost 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.
