Questions

It can create purchases and save their lines, save sale order lines, create and update products, update suppliers and create stock adjustments.

Does the AI see my Cin7 Core credentials?

No. Your Cin7 Core 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. Stock adjustments change your stock levels, and product and supplier updates change master data, so these 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 with no credit card required. Paid plans bill per completed task. You also need your own Cin7 Core account.

I have more than one company in Cin7 Core. Which one does the AI use?

Each company in Cin7 Core has its own Account ID, and the AI works in the company whose Account ID and Application key you paste. The AI can read the connected company's details to confirm which one it is.
