Use CallForMe in ChatGPT

Turn on developer mode in ChatGPT settings, create an app with the URL https://callforme.tel/mcp and OAuth authentication, then click Connect. A tab opens and closes; no email or card. Pick it from the plus menu in a chat. The first real call shows one setup link to add $10.

ChatGPT does not place outbound calls to businesses on its own. Adding CallForMe as a developer-mode app gives it that ability inside a normal chat.

Install

  1. In ChatGPT, open Settings, then Apps & Connectors (on some accounts it's under Security and login), and turn on Developer mode.
  2. Choose Create to add a new app.
  3. Name: CallForMe. MCP server URL: https://callforme.tel/mcp
  4. Authentication: OAuth (not "No authentication").
  5. Confirm that you trust the app, save, and click Connect.
  6. In a new chat, open the + menu, choose Developer mode, and select CallForMe.

Developer mode is available on paid plans (Plus, Pro, Business, Enterprise, Edu). Menu names move around between ChatGPT releases, so if you don't see a label above, search Settings for "developer mode".

Connecting your account

When you create the app with OAuth selected, ChatGPT shows a Connect button. Click it. A browser tab opens and closes by itself. There's no email, no form and no card. That creates your CallForMe account.

Your first call

The only other step comes once, the first time your agent places a real call. CallForMe answers with a short setup link like https://callforme.tel/go/k7m2q, and your agent shows it to you.

  1. Open the link. It shows the exact call about to be placed: who, what number, and the goal.
  2. Add $10. Your card is saved and auto-reloads, so you won't see this page again. Creators can claim credit with their email instead.
  3. The page says you're done. Tell your agent to continue, and the phone starts ringing.

After that, every chat and every session just calls. If you later add CallForMe to a second agent, its first call link recognizes you (when you're signed in on that browser) and links it to your account in one click, with no second payment. More in how setup links work.

Want to test it first? Ask your agent to call Maple Street Pizza, a fictional restaurant, at (469) 770-7412. Demo calls are free, with no payment, up to 5 a day.

If the Connect step doesn't show up

If your version of ChatGPT can't do OAuth sign-in, use one of these instead:

  • https://callforme.tel/mcp/open needs no sign-in. Your agent gets a setup link in each new session unless it saves the account_key it receives.
  • A personal URL, https://callforme.tel/mcp/k/<your key> as the app's MCP server URL with No authentication, using a key you create on the account page.

Tips for ChatGPT

  • ChatGPT asks you to approve write actions. Placing a call is one, so expect a confirmation before it dials.
  • Ask ChatGPT to "keep checking the call until it ends" so it keeps polling get_call and can answer the business's questions.

Try it

Paste this into ChatGPT:

Call my dentist, Parkside Dental, and ask to be put on the cancellation list for a cleaning in the next two weeks. Weekday mornings work best. My name is Sam Lee.

Questions

Does ChatGPT have a built-in way to call businesses?

Not as of September 2026. CallForMe adds it through an MCP app in developer mode.

Do I need a paid ChatGPT plan?

Developer mode apps need a paid plan. You can also call CallForMe from any agent with a shell or from the REST API.

Why does ChatGPT ask me to confirm before calling?

ChatGPT treats tools that change things in the world as write actions and asks first. That's a good check before a real phone call goes out.
