Make Setup available Set up from a computer

Give Make a phone.

A scenario makes one approved call and routes the answer onward.

1 free calling minute for eligible new accounts. No card required.

Connect with a prompt

Copy this prompt into Make. Your agent can help you finish the setup.

Connect Open Calls to Make so you can make phone calls for me.
Follow https://opencalls.dev/connect/agent?client=make. The MCP server address is https://opencalls.dev/mcp. Use the connection method your app supports; if you cannot set it up yourself, give me the exact steps.
Help me sign in and approve access. Keep any connection key in a secure credential field, never in this chat.
Confirm the connection by reading my account, available free calling time and balance. Then tell me you’re ready and ask who I’d like to call. A successful account read completes setup; an introductory call and callback verification are optional for ordinary calls.
Do not place a call during setup. Before each call, show the recipient, objective and quoted maximum charge, then wait for my approval.

1Copy the prompt. It includes the Open Calls address and setup guide.
2Paste it into your agent. If it cannot add the connection itself, it will guide you through its settings.
3Approve access and check your balance. Sign in to Open Calls when asked. Setup never starts a call.

You’re ready when your agent can read your Open Calls balance. Keep any connection key in its secure credential field, never in chat.

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
Handle a phone menu within your approved limits
Wait on hold and invite you to speak directly when available for your account and language
Call several places with the same question and compare the answers
Keep confirmed answers separate from anything left unanswered

Joining and waiting on hold depend on your account and language availability, shown before you start a call. When joining is available, verify your callback number and accept the private invitation before speaking directly. Callback and recipient prompts support English, Hebrew, Spanish, French, German, Portuguese, Arabic and Italian. Live translation is available in beta for supported language pairs.

Questions

What does a call cost?

Your assistant quotes the maximum first. Calls are billed by the second with a minimum total for connected calls. See pricing and destination rates.

Does my assistant call anyone without asking?

Permission to connect is separate from permission to call. Review the recipient, objective and maximum price before starting each call. A connection cannot approve purchases or raise your spending limits.

Can I try it before adding credit?

Check your account for available calling time and current calling availability. Reading a quote or looking at a fictional example never starts a call.

Which countries can it call?

Your account shows current calling availability. Check destination rates for supported number types; your account also shows current availability.
