What do you want Harvest and Kartra 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.

Questions
Harvest and Kartra, answered
What can start an automation from Harvest?
Any of Harvest's 16 triggers in the catalog, including New Client, New Contact, New Expense and New Invoice. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Kartra when something happens in Harvest?
Any of Kartra's 23 actions, including Create New Lead, Assign Tag to Lead, Edit Lead and Edit Subscription. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Kartra to Harvest?
Kartra has no triggers in the catalog today, so automations start in Harvest. If you need the other direction, ask: your agent reads Kartra's API documentation and adds it.
Do I have to build a connector for Harvest or Kartra?
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 Harvest and Kartra 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.
