Questions

What can the AI do in Megaventory?

The AI can find products, categories, prices, stock levels, inventory locations, suppliers, clients, contact persons, document types, sales orders, sales quotes, purchase orders, documents, work orders and account settings. It can create and update products, suppliers, clients, sales orders, sales quotes and purchase orders, set stock quantities and cancel sales or purchase orders.

Does the AI see my Megaventory API key?

No. Your Megaventory API key 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. Changing stock, saving orders and cancelling orders 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 HeyMyApps 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?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Megaventory account.

How does the AI change stock quantities?

It sets the quantity of a product SKU at a specific inventory location. Megaventory records each change as a stock adjustment, so it shows up in your stock history. You can switch this tool off or require approval before each change.
