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)Postman holds the workspaces, collections, environments, monitors and mock servers your API work runs on, while Mailtrap handles the contact lists and email that keep people informed. Joining them means a new collection, environment or monitor in Postman can create the right Mailtrap list, contact or message without anyone copying details by hand.

Questions
Postman and Mailtrap, answered
Can something in Mailtrap start one of these setups?
No, Mailtrap has no triggers listed here, so every setup begins with an event in Postman such as a new collection, environment, workspace, mock server or monitor. Mailtrap takes the actions, like sending an email, creating a contact or adding a contact list.
How do I know the email goes to the right Mailtrap list?
The agent can look up lists in Mailtrap with Get Lists or Get Contact list before sending, so the message only goes out when the list you named exists. It tests every scenario, including the case where no matching list is found.
What can start an automation from Postman?
Any of Postman's 5 triggers in the catalog, including New Collection, New Environment, New Mock Server and New Monitor. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Mailtrap when something happens in Postman?
Any of Mailtrap's 17 actions, including Add Contact list, Add Email campaign, Send Email and Update Contact. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Mailtrap to Postman?
Mailtrap has no triggers in the catalog today, so automations start in Postman. If you need the other direction, ask: your agent reads Mailtrap's API documentation and adds it.
Do I have to build a connector for Postman or Mailtrap?
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 Postman and Mailtrap 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.
