Try asking

  • “Text +37251234567: Your order is ready for pickup.”

    The AI sends the message by SMS and returns a message ID. Sending uses your Messente credit.

  • “Was the reminder we just sent delivered?”

    It checks the delivery status using the message ID from the send.

  • “Send the offer by Viber, and fall back to SMS if Viber does not work.”

    It sends one message with Viber and SMS listed in order, so the next channel is tried if the first one fails.

What your AI can do

Messages

Send SMS, Viber and WhatsApp messages with channel fallback, schedule them for later, cancel scheduled ones and check delivery status.

Phonebook and groups

Create, update and delete contacts, create and rename groups, and add or remove contacts from groups.

Blacklist, lookups and statistics

  • “Add Maria Tamm, +37251234567, to the 'VIP customers' group.”

    It creates the contact in the phonebook and adds her to the group.

    It checks the blacklist. If you ask, it can remove the number so it can receive messages again.

Questions

What can the AI do in Messente?

It can send SMS, Viber and WhatsApp messages, schedule and cancel them, and check delivery status. It can create, update and delete phonebook contacts, manage groups and group membership, manage the blacklist, look up phone numbers, read sending statistics and list or read WhatsApp templates.

Does the AI see my Messente API password?

No. Your Messente API username and password 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 with lookups only. Sending a message reaches real people and uses credit, number lookups are charged, and deleting a contact is permanent. 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 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 Messente account, and messages and number lookups use your Messente credit.

Can the AI schedule a message for later?

Yes. When it sends a message, the AI can set a send time so the message goes out later. Until then, it can cancel the scheduled message by its ID.
