Build solutions, not workarounds.
What do you want Klaviyo and Lob to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne 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

Questions
Klaviyo and Lob, answered
What can start an automation from Klaviyo?
Any of Klaviyo's 2 triggers in the catalog, including New Event and New or Updated Profile. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lob when something happens in Klaviyo?
Any of Lob's 40 actions, including Create Address, Create Bank Account, Create Template and Send Check. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lob to Klaviyo?
Lob has no triggers in the catalog today, so automations start in Klaviyo. If you need the other direction, ask: your agent reads Lob's API documentation and adds it.
Do I have to build a connector for Klaviyo or Lob?
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 Klaviyo and Lob 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.
