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

## What do you want Sellsy and AddressZen 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.

### 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.

Questions

## Sellsy and AddressZen, answered

###

Any of Sellsy's 9 triggers in the catalog, including New Company, New Contact, New Opportunity and New Task. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in AddressZen when something happens in Sellsy?

Any of AddressZen's 9 actions, including Find addresses by search term, Find places by search term, Freeform US Address Verification and Get address. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from AddressZen to Sellsy?

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

###

### Do I have to build a connector for Sellsy or AddressZen?

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 Sellsy and AddressZen 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.

###
