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

Connect with a prompt

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

Connect Open Calls to your agent so you can make phone calls for me.
Follow https://opencalls.dev/connect/agent. 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.

MCP address

Need to set it up manually?

Your agent checks which connection method it supports, then helps you approve access.

1Create a connection key below with only the permissions you need.
2Add the MCP address and store the key in the connector's secure Bearer credential field.
3Ask for your balance first. Approve each call's recipient, objective and maximum.

Developer guide

You approve the call

Connecting only grants the access you choose. Before every call, review the recipient, objective and maximum charge. Your agent waits for approval before dialing.

Joining depends on your account and language availability, shown before you start a call. When available, ask your AI to bring you in and accept your verified callback to speak directly. Callback prompts support English, Hebrew, Spanish, French, German, Portuguese, Arabic and Italian. Live translation is available in beta for supported language pairs.
