Questions

Mailosaur, answered

Is there a Mailosaur MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with Mailosaur. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run Mailosaur actions on demand, or have APIANT build, test and run automations that use Mailosaur. Nothing to install.

What can start an automation from Mailosaur?

Any of Mailosaur's 1 trigger in the catalog, including New message. Describe the moment in plain language and your agent picks the right one.

What can your agent do in Mailosaur?

Any of Mailosaur's 10 actions, including Send email, Update server, Add server and Find messages by criteria. Your agent maps the data both ways and tests every scenario before it ships.

Can I use Mailosaur directly from Claude, ChatGPT or Cursor?

Yes. Connect your AI client to APIANT once and it works with Mailosaur two ways. Ask it to do something in Mailosaur 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 on its own. A one-off action uses your plan's tasks the same way an automation step does.

Do I need to write code against the Mailosaur API?

No. APIANT connects to the Mailosaur API for you, with your Mailosaur API key. Describe what you want in plain language and your agent builds it on the Mailosaur triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the Mailosaur API documentation and adds it.

Which apps can Mailosaur connect to?

Any app in the catalog; the list on this page pairs Mailosaur with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

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.
