Describe the whole flow and it is built, tested on every scenario and kept running. Todoist **3** triggers Todoist **30** actions Resend **28** actions What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it. ## What do you want Todoist and Resend to do together? 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 Todoist's 3 triggers in the catalog, including New Completed Task, New Incomplete Task and New Project. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Resend when something happens in Todoist? Any of Resend's 28 actions, including Create API Key, Create Contact, Create Domain and Create Segment. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Resend to Todoist? Resend has no triggers in the catalog today, so automations start in Todoist. If you need the other direction, ask: your agent reads Resend's API documentation and adds it. ### ### Do I have to build a connector for Todoist or Resend? 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 Todoist and Resend 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.
