What do you want Reply and SigningHub 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.

Questions
Reply and SigningHub, answered
What can start an automation from Reply?
Any of Reply's 7 triggers in the catalog, including New Email Opened, New Emails Sent, New Link Clicked and New Person Bounce. Describe the moment in plain language and your agent picks the right one.
What can your agent do in SigningHub when something happens in Reply?
Any of SigningHub's 11 actions, including Create Integration URL, Create Package, Add Digital Signature and Add Document. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from SigningHub to Reply?
SigningHub has no triggers in the catalog today, so automations start in Reply. If you need the other direction, ask: your agent reads SigningHub's API documentation and adds it.
Do I have to build a connector for Reply or SigningHub?
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 Reply and SigningHub 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.
