Integration
Connect Mailjet and Slack
When New Contact in List fires in Mailjet, your agent runs Send Message in Slack, or New Message Posted to Channel in Slack to Create Contact in Mailjet. 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 Mailjet and Slack 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)Slack is where your team talks; Mailjet holds your contacts and sends the mail. Connecting them lets a Slack message, reaction or new member feed straight into a Mailjet contact list, and lets new Mailjet contacts or lists show up as Slack messages and channels. The agent builds the whole flow, tests every scenario and keeps it running.

Questions
Mailjet and Slack, answered
Can I check whether someone is already in Mailjet before creating them?
Yes. The Get Contact action retrieves a contact by ID or email, so the flow can look first and only run Create Contact and Add Contact to List when nothing comes back.
Will new Mailjet contacts show up in Slack right away?
The Mailjet triggers for new contacts, contacts added to a list and new contact lists are polling triggers, so they pick up records on each check. From there you can post a channel message, send a direct message or create a channel in Slack.
What can start an automation from Mailjet?
Any of Mailjet's 3 triggers in the catalog, including New Contact in List, New Contact List and New Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Slack when something happens in Mailjet?
Any of Slack's 60 actions, including Create Channel, Send Message, Create Canvas and Create Channel Canvas. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Slack to Mailjet?
Yes. When something happens in Slack, your agent can act in Mailjet too. This page covers both directions: Slack's triggers and Mailjet's actions are listed here as well.
Do I have to build a connector for Mailjet or Slack?
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 Mailjet and Slack 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.
