Connect Claude & ChatGPT to ChatArchitect
Ask your AI to send a WhatsApp message to a customer, check which templates are approved, or find out why a message did not arrive. Through ChatArchitect it can send text, media and template messages from your WhatsApp Business API number, create or change templates, and list the last messages that failed to deliver.
Free plan, no credit card. Takes about a minute.
Try asking
“Send +4512345678 a WhatsApp message saying their order is ready for pickup.”
The AI sends the text message from your WhatsApp number. It is delivered right away and cannot be recalled.
“Which WhatsApp templates do we have approved?”
It lists the approved templates on your number with their names and content.
“Send the order_confirmation template to +4598765432.”
It checks the template in your list and sends it to the number as a template message.

Questions
What can the AI do in ChatArchitect?
The AI can send WhatsApp messages with text, media or a template, list your approved templates, create or change templates, and list the last 10 messages that failed to deliver.
Does the AI see my ChatArchitect credentials?
No. Your APP_ID and APP_SECRET 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 only listing templates and failed messages. A WhatsApp message reaches the customer at once and cannot be recalled, so sending can require your approval before it runs. 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 ChatArchitect account with a connected WhatsApp Business API number.
Can the AI read replies from my customers?
No. ChatArchitect delivers incoming messages and delivery statuses by webhook, not through tools the AI can call. The AI can send messages and templates and see failed messages, but it cannot read what customers write back.
