Connect Claude & ChatGPT to TNZ

Ask your AI to text a customer, email a group or schedule a reminder, and it sends it through your TNZ account. It can send SMS, email, text-to-speech calls and WhatsApp template messages, check delivery status and read inbound replies. It also keeps your TNZ address book in order, with contacts, groups and opt-outs.

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

Try asking

“Text +64 21 555 0123 that their order is ready for pickup.”
The AI sends the SMS through TNZ and returns the message ID so you can check delivery.
“Did the SMS I sent this morning arrive?”
It reads the status and delivery results for that message ID.
“Which SMS replies came in during the last two hours?”
It lists the inbound SMS and replies received in that time window.

What your AI can do

SMS, email, voice and WhatsApp

Send to a number, address, contact or group, now or at a set time, and use test mode to simulate without sending.

Delivery and replies

Check the status of sent SMS, email, calls and WhatsApp, and read inbound SMS and WhatsApp from the last 7 days.

Contacts, groups and opt-outs

Search, create, update and group address-book contacts, and add or list opt-outs per message type.

“Schedule a reminder SMS to the Workshop group for 8 am tomorrow.”
It sends the SMS to the group with a send time. You can reschedule or cancel it before it goes out.
“Add Mia Tane from Harbour Cafe to the Suppliers group.”
It searches the address book first, creates the contact if needed and adds her to the group.
“Stop sending SMS to +64 27 555 0199.”
It opts the number out of SMS, so it receives no more text messages from your account.

Questions

What can the AI do in TNZ?

It can send SMS, email, text-to-speech voice calls and WhatsApp template messages, check their status, and read inbound SMS and WhatsApp. It can cancel or reschedule a scheduled SMS. It can also search, create, update and delete contacts, manage groups, and add or list opt-outs.

Does the AI see my TNZ Auth Token?

No. Your TNZ Auth Token is encrypted at rest and never shown to the AI. After you save it, it is 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 with status checks and contacts. Sending real messages is charged by TNZ, and deleting a contact is permanent, so those actions 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 PipMCP 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?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own TNZ account, and TNZ charges for the messages and calls you send.

Can I test a message without sending it?

Yes. The send tools for SMS, email, voice and WhatsApp have a test mode. Ask the AI to use mode=Test, and TNZ simulates the send without delivering a real message.
