Questions

What can the AI do in Hilos?

The AI can search and read contacts, WhatsApp templates, conversations, flow runs, flow run contacts and team members. It can create, update and delete contacts, send WhatsApp template messages, start flows and update conversations.

Does the AI see my Hilos API key?

No. Your Hilos credentials 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 read-only. Sending a template, starting a flow and deleting a contact can each require your approval before they run. Deleting a contact cannot be undone. 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 Hilos account.

Can the AI send any WhatsApp message it writes?

No. The AI sends WhatsApp template messages: it picks one of your templates and fills in its variables. Flows it starts can also send messages. There is no tool for sending free-form text.
