## What do you want Vast.ai and Shift4 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`

Questions

## Vast.ai and Shift4, answered

###

### What can start an automation from Vast.ai?

Any of Vast.ai's 1 trigger in the catalog, including New Matching Offer. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Shift4 when something happens in Vast.ai?

###

### Can it also run from Shift4 to Vast.ai?

Shift4 has no triggers in the catalog today, so automations start in Vast.ai. If you need the other direction, ask: your agent reads Shift4's API documentation and adds it.

###

### Do I have to build a connector for Vast.ai or Shift4?

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 Vast.ai and Shift4 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?
