Connect Claude & ChatGPT to Vapi

Ask your AI how yesterday's calls went, why a call ended, or what an assistant says first, and get the answer from your Vapi account. It can read assistants, squads, calls with transcripts and summaries, phone numbers, campaigns, chats, tools, knowledge bases and dashboard metrics. It can also update an assistant, start an outbound call, create or stop a campaign and chat with an assistant in text, with your approval if you want it.

Free plan, no credit card. Takes about a minute.

Try asking

“Summarize yesterday's calls to our support assistant.”
The AI lists calls for that assistant and date, and reads each call's summary, duration and why it ended.
“Why did the last call on our sales number end so quickly?”
It finds the call and reads its status, end reason and technical logs.
“Have the support assistant greet callers in Danish in its first message.”
It updates the assistant's first message. The next calls use the new setting.

What your AI can do

Calls and transcripts

List and read calls with status, duration, cost, transcript, summary, recording links and end reason, plus technical call logs.

Assistants and squads

Read and update assistants, read squads, tools, knowledge bases and files, and test an assistant in a text chat.

Outbound calls and campaigns

Start outbound calls from your phone numbers, create, update or cancel campaigns, and see dashboard metrics.

“Call +4512345678 with the booking assistant from our main number.”
It starts an outbound call right away. The person is phoned and the call is billed to your Vapi account.
“How is the October campaign going?”
It reads the campaign with call counters and lists its contacts by call status.
“Test the booking assistant: ask it for a table for four on Friday.”
It sends the message as a text chat and returns the assistant's reply, so you can check it without a phone call.

Questions

What can the AI do in Vapi?

It can read assistants, squads, calls, call logs, phone numbers, campaigns and their contacts, chats, tools, knowledge bases, files and the metrics overview. It can update assistants, start outbound calls, create and update campaigns and send a text message to an assistant.

Does the AI see my Vapi credentials?

No. Your Vapi credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Starting a call or a campaign phones real people and is billed to your Vapi account, and updating an assistant changes how it handles the next calls. These can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Vapi account, and calls are billed to it.

Can the AI phone people on its own?

Only if you switch on the call or campaign tools. A call starts right away and is billed to your Vapi account, and a campaign phones every customer on its list automatically. You can leave these tools off, or require your approval so you check the number and assistant first. Cancelling a campaign deletes its scheduled calls.
