Integration
Connect Klaviyo and Mailchimp
When New Event fires in Klaviyo, your agent runs Add Member Event in Mailchimp, or Member Cleaned (instant) in Mailchimp to Get Profile by Email in Klaviyo. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
What do you want Klaviyo and Mailchimp 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
Claude Code
Run this in the directory you want to work in.
claude mcp add --transport http -s project apiant-ai https://mcp.apiant.aiStart Claude Code there, approve the server, and sign in in the browser page it opens.
Claude Code guide (opens in a new tab)Claude, web and desktop
Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.
Setup guide (opens in a new tab)Cursor
Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.
Setup guide (opens in a new tab)Zed
Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.
Setup guide (opens in a new tab)Codex and the ChatGPT desktop app
Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.
Setup guide (opens in a new tab)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.
Setup guide (opens in a new tab)Teams that run Klaviyo and Mailchimp side by side usually keep one as the sending tool and the other as the record of who can be emailed. Connecting them means a profile created in Klaviyo can land in a Mailchimp audience, and a bounce or profile change in Mailchimp can be reflected back on the Klaviyo profile, without anyone copying addresses by hand.

Questions
Klaviyo and Mailchimp, answered
Can a bounce in Mailchimp stop the same address from being emailed in Klaviyo?
Yes. The Member Cleaned trigger in Mailchimp can look up the person with Get Profile by Email in Klaviyo and, when a profile comes back, run Suppress Profile so that address is no longer sent email marketing.
What happens if someone exists in Klaviyo but not yet in Mailchimp?
The Add or Update Member action in Mailchimp upserts by email, so it creates the member when there is no match and updates the existing one when there is. You can also use Search Members first if you want the run to behave differently for people already on the audience.
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 Mailchimp when something happens in Klaviyo?
Any of Mailchimp's 164 actions, including Add Member Event, Add or update member, Create audience and Create Campaign. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mailchimp to Klaviyo?
Yes. When something happens in Mailchimp, your agent can act in Klaviyo too. This page covers both directions: Mailchimp's triggers and Klaviyo's actions are listed here as well.
Do I have to build a connector for Klaviyo or Mailchimp?
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 Mailchimp 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.
