Connect Claude & ChatGPT to Tall Bob

Ask your AI to text a customer, send a campaign to a contact list or check who replied. It can send SMS and MMS from your registered sender addresses, work out what a message will cost first, and check your credit balance. It can also create and find contacts, manage contact lists and opt-outs, and read replies, delivery receipts and inbound MMS.

Try asking

“Text 0412 345 678 that their order is ready for pickup.”
The AI picks one of your sender addresses and sends the SMS. It is delivered at once and charged to your balance.
“What would this message cost to send?”
It calculates the price of the SMS text before anything is sent.
“Who replied to yesterday's reminder texts?”
It lists the SMS replies received, with the number and the reply text.

What your AI can do

SMS, MMS and campaigns

Send single SMS and MMS, send a campaign to a whole contact list, and check the price of a message and your balance.

Contacts and lists

Create, find and delete contacts, add or remove them from contact lists, and manage opt-outs.

Replies and receipts

Read SMS replies, delivery receipts and inbound MMS, and see which campaigns a contact has received.

“Add Sam Carter, 0400 111 222, to the VIP list.”
It checks whether the contact exists by your external ID, creates the contact if not, and adds them to the VIP contact list.
“Did last week's campaign get delivered?”
It finds the campaign, lists its recipients and reads the delivery receipts, so you can see what was delivered and what failed.
“Opt out 0433 987 654 from our messages.”
It sets the mobile number as opted out, so it stops getting your messages.

Questions

What can the AI do in Tall Bob?

It can send SMS and MMS, send campaigns to contact lists, calculate message prices and check your balance. It can create, find and delete contacts, manage contact lists and opt-outs, and read campaigns, templates, sender addresses, replies, delivery receipts and inbound MMS.

Does the AI see my Tall Bob API key?

No. Your Tall Bob API username and key 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 read-only tools. Sending SMS, MMS and campaigns reaches real people and is charged to your balance, and deleting a contact is permanent. These actions can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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, and you do not need a credit card to start. Paid plans are billed per completed task. You also need your own Tall Bob account, and messages you send are charged to your Tall Bob balance.

Which sender can the AI send from?

The AI sends from a sender address or number registered on your Tall Bob account. It can list your sender addresses first and use one of them as the sender.
