Connect Mailosaur and PassEngine
When New message fires in Mailosaur, your agent runs Send pass email in PassEngine, or New Client in PassEngine to Send email in Mailosaur. 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 Mailosaur and PassEngine 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.

Any of PassEngine's 11 actions, including Create Client, Create Pass, Send pass email and Update Pass. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from PassEngine to Mailosaur?
Yes. When something happens in PassEngine, your agent can act in Mailosaur too. This page covers both directions: PassEngine's triggers and Mailosaur's actions are listed here as well.
Do I have to build a connector for Mailosaur or PassEngine?
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 Mailosaur and PassEngine 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.
