Connect ChatGPT to your store and ask it about your Tacey records in plain words, such as "what plan is my store on, how many orders have I used this period, and how many refunds are still waiting on me?". On every live store ChatGPT can only read. It cannot change an order, merge orders, hold or release an order, change a Tacey setting, send an email to a customer, refund anything or move money, and nothing in Tacey or in ChatGPT lets you switch that on. We are testing changes from the chat on our own test store only; they are switched off for every live store. It never sees a customer's name, email, phone number or street address.

This article walks through every screen, in order. For what the connection can and cannot do in general, and for Claude, see Use Tacey from Claude or ChatGPT and Connect Claude to Tacey, step by step.

The Integrations page also lists ChatGPT steps. Those steps use older ChatGPT menu names ("Settings", "Apps", "Developer mode"). Follow the steps in this article instead, which are the ones we ran.

Choose Advanced OAuth settings. It only opens after you have entered the address, because ChatGPT reads what Tacey's server offers.

Tacey is built to offer only `mcp:read` on a live store, so you should see just that one. We have not yet looked at this screen against a live store.

Then tick I understand and want to continue (ChatGPT warns that custom servers carry risk and to connect only to servers you trust), and choose Create as a plugin.

Tacey shows you what you are about to allow before anything is connected. The page is titled Let ChatGPT read your Tacey records? and is shown in the language Tacey is set to for your store. We saw it in English and in German.

Choose Approve. Choose Cancel if you changed your mind; nothing is connected.

What "approve" gives ChatGPT, in plain words. ChatGPT does not get your Shopify password or Tacey login. Tacey gives ChatGPT a connection that works only for your store and only for reading. Tacey lists it on your Integrations page with when it was connected and last used, and it stops working the moment you disconnect it.

Your browser returns to ChatGPT's Plugins page, and your plugin appears under Created by you. In Tacey, Integrations, then ChatGPT now shows Connected, who connected it and when.

In our test, ChatGPT answered from Tacey with the plan name, the orders used out of the plan's total, the orders remaining, and the refunds and other money actions waiting on us. No customer name, email, phone number or address appeared.

Check the numbers that matter. In our first test ChatGPT read the "orders remaining" figure as "orders used" in its first reply, and corrected it in the second. Tacey sent the right figures both times. Compare any figure that matters with the Tacey page the assistant links to.

On every live store the connection is read only. Changes from the chat are switched off for every live store, so you will not find a switch for them in Tacey, a box for them on the approval screen, or a change permission on ChatGPT's list in Step 3. Until they are turned on, ChatGPT can tell you what needs doing and link you to the page in Tacey, and you press the button yourself.

What we have tested, on our own test store only: we added a second ChatGPT connection that was allowed to ask for the address permission as well as reading. Asked to change the unit on one order, ChatGPT first said the new address could not be confirmed and asked whether to go ahead. Its own approval box then appeared with a warning, Suspicious content: opaque payload, with the choices Allow once and Always allow. It is a warning and not a block. It appears because ChatGPT is handed a signed code that proves Tacey prepared the change, and ChatGPT cannot read the code. We are working on removing the warning before any change is switched on for live stores; a first fix did not remove it. After Allow once, ChatGPT reported the unit was set, with no charge or refund and no message to the customer, and we checked the order in Shopify and in Tacey's record of changes. If ChatGPT is given an order number where Tacey expects Shopify's own order id, it can answer that no address check exists for the order; we saw this and it is being fixed. None of this is available to you today, so you will not see that warning on a live store.

Open Integrations, then ChatGPT. Under What this assistant read you see the last 30 days: how many requests were made, how many records were read, and one line per request with the kind of information it asked for and the time. Tacey keeps counts and times only. It never keeps your question or ChatGPT's answer. We have not yet checked this list against a real ChatGPT run.

To connect again later, repeat Steps 4 to 6. We have not yet recorded a reconnect in ChatGPT after a disconnect.

ChatGPT may remember the list of things it can look up from the moment it connects. We have not confirmed how ChatGPT picks up new ones. If you ask for something Tacey can do and ChatGPT says it cannot, remove the plugin in ChatGPT and add it again (Steps 2 to 6), or look for a refresh option on the plugin, then ask in a new chat.
