Give Make a phone.
Real calls, your approval, grounded answers.

Open Calls works with Make through its MCP Client and the REST API: a scenario creates one approved phone call and uses the grounded answer downstream.

What Make can do with a phone

  • Check whether a shop has something in stock and what it costs
  • Ask a clinic, office or hotel a question and bring back the answer with the quote
  • Wait through a phone menu and hold, then bring you in when a person answers
  • Call several places with the same question and compare the answers
  • Translate a call both ways when you join

How it connects

Make's MCP Client or the REST API (HTTP module) with the signed result webhook.

  1. Create an API key under Connections.
  2. Add the MCP server in Make's MCP Client, or use the HTTP module against the REST API.
  3. Quote, then create the call with an idempotency key and maximum charge.
  4. Use the settled result, or the signed webhook, in the next module.

Questions

What does a call cost?

Pay as you go at $0.25 per minute of AI conversation, billed by the second after a one-minute minimum, with a cheaper waiting rate while the line keeps the AI on hold. Your assistant quotes the maximum before every call and you approve it.

Does my assistant call anyone without asking?

No. Every call needs your explicit approval and a maximum charge, calls are information-only, and you can stop a call at any time.

Is there free calling time to try it?

Yes. Sign in with Google, give your mobile number, and your AI calls you for a free minute to introduce itself, with no card. After that, add credit to call anyone.

Which countries can it call?

United States, Canada, Israel and the United Kingdom today, with per-destination rates shown before you approve.

Other assistants

Any other MCP client or REST integration works too: see the developer guide.
