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.

Connecting them means an inbound Twilio SMS or call can land in the right Slack channel or a direct message, and a number posted in Slack can be looked up in Twilio for carrier and caller name without leaving the conversation.

Yes. The New Call trigger in Twilio can start a flow that uses Lookup Phone Number for caller name and line type, then posts the result to a channel or sends a direct message in Slack. ### ### Can Slack send an SMS reply back through Twilio? No. The listed Twilio actions read data only: get or list calls and messages, list your phone numbers, and look up a number. Slack can receive and display that information, but sending an outbound SMS is not among the listed actions. ### ### What can start an automation from Twilio? Any of Twilio's 4 triggers in the catalog, including New Call, New Message Received, New Incoming Call and New SMS received. Describe the moment in plain language and your agent picks the right one. ### ### What can your agent do in Slack when something happens in Twilio? Any of Slack's 60 actions, including Send Direct Message, Send Message, Create Canvas and Create Channel. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from Slack to Twilio? Yes. When something happens in Slack, your agent can act in Twilio too. This page covers both directions: Slack's triggers and Twilio's actions are listed here as well. ### ### Do I have to build a connector for Twilio or Slack? 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 Twilio and Slack 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.
