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

## What do you want Formstack Documents and Iucto 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.

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.

## Formstack Documents and Iucto, answered

###

### What can start an automation from Formstack Documents?

Any of Formstack Documents's 1 trigger in the catalog, including New Merged Document. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Iucto when something happens in Formstack Documents?

###

### Can it also run from Iucto to Formstack Documents?

###

###

### Can my AI client use Formstack Documents and Iucto 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.
