Give your AI client this address. `https://mcp.apiant.ai` One 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.ai` Start Claude Code there, approve the server, and sign in in the browser page it opens.

Any of eSignatures's 4 triggers in the catalog, including Contract Signed, Contract Withdrawn, Signer Declined Signature and Signer Viewed Contract. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Mailjet when something happens in eSignatures? Any of Mailjet's 16 actions, including Create Contact, Create Contact List, Create Contact Property and Send Email. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Mailjet to eSignatures? Yes. When something happens in Mailjet, your agent can act in eSignatures too. This page covers both directions: Mailjet's triggers and eSignatures's actions are listed here as well. ### ### Do I have to build a connector for eSignatures or Mailjet? 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 eSignatures and Mailjet 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.
