Connect Claude & ChatGPT to SMSBOX

Ask your AI to text a customer, a whole contact group or a list of numbers through SMSBOX, now or at a set time. It can build and update contact groups, check what was sent to a number, and list or cancel scheduled messages. It also tells you your remaining credits and which sender IDs you have.

Try asking

“Text 33612345678: your order is ready for pickup.”

“Send the store closing notice to the Staff group tomorrow at 8:00.”
It sends the SMS to every number in the group, scheduled for that date and time in Paris time.
“Create a group called Drivers with these five numbers.”
It creates the contact group with the name and numbers in international format.

Questions

What can the AI do in SMSBOX?

The AI can send SMS to numbers or contact groups, schedule them, create and update groups, list sent and scheduled messages, cancel scheduled ones, and read your credit balance, sender IDs and default sender.

Does the AI see my SMSBOX credentials?

No. Your SMSBOX API key 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. Sending an SMS reaches real people and uses credits, and cancelling a scheduled message cannot be undone, so these 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 SMSBOX account, and messages use your SMSBOX credits.

Which time zone is used for scheduled messages?

Scheduled sends use Paris time. When you ask the AI to send at a certain date and hour, it passes that date and time to SMSBOX, which sends the message then. You can list or cancel scheduled messages until they go out.
