    You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:

Questions

What can the AI do in Wherefour?

The AI can read inventory items, stock lots, customers, suppliers, sales orders, shipments, quotes, invoices, purchase orders and order statuses. It can create and update customers and sales orders, create quotes and invoices, and ship a sales order.

Does the AI see my Wherefour password?

No. Your Wherefour username and password 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 lookups only. Shipping an order or creating an invoice can require your approval before it runs. 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 Wherefour account.

Why should I create a separate Wherefour user?

Wherefour's API signs in with a user's username and password, so the AI works with that user's access. A dedicated user with a limited role keeps its access narrow, on top of the tools you switch on in PipMCP, and you can change its password without affecting anyone else.
