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

## What do you want Ontraport and OnceOnly 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.

###

### What can your agent do in OnceOnly when something happens in Ontraport?

###

### Can it also run from OnceOnly to Ontraport?

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

###

### Do I have to build a connector for Ontraport or OnceOnly?

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 Ontraport and OnceOnly 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.
