Questions

What can the AI do in Smsbox.be?

It can send SMS, WhatsApp and voice messages, send one-time codes and check them, and list sent and received messages. It can manage phonebook contacts and groups, look up and format numbers, create tracking links and read your credit balance.

Does the AI see my Smsbox.be 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, so you can start read-only. Sending messages and codes reaches real people and some of it uses credit, 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 SMSBOX account, and messages use your SMSBOX credit. PipMCP is not affiliated with SMSBOX.

Can the AI test an SMS before it goes out?

Yes. The SMS tool has a test option that tries the message without sending it. Without it, SMS, WhatsApp and voice messages go out immediately, and SMS and voice messages use credit.
