Introduction
Connect your ChatGPT account and ask questions about your WISK data in plain language: what's in stock, what a recent invoice contained, how sales compare to last week, what to order this week.
ChatGPT reads your live WISK data through a secure connection that you control and can switch off at any time. Custom MCP connectors like WISK are added through ChatGPT's Developer Mode, so the setup below happens there.
Setting it up takes about 10 minutes.
Before you Start
You need:
A ChatGPT Business, Enterprise, or Edu plan. Custom MCP connectors (Developer Mode) are currently in beta and are not available on ChatGPT Free, Plus or Pro accounts.
Developer Mode turned on for your account. On Enterprise/Edu, a workspace admin grants this in Workspace Settings → Permissions & Roles → Connected Data → Developer mode. On Business, only admins/owners can turn it on, under Settings → Apps → Advanced Settings.
A WISK login (the email and password you use at web.wisk.ai). No API key or technical credentials are needed.
WISK never sees what you ask ChatGPT, and ChatGPT only sees the WISK data you would see yourself.
Step 1 — Turn on Developer Mode
Click your profile picture and select Settings.
Open the Apps tab, then Advanced Settings.
Toggle Developer mode on. ChatGPT will warn you that custom connectors run third-party code on your behalf — accept this to continue.
Step 2 — Add WISK as a custom connector
In the Apps section, select Create (shown as New app or Create connector).
Fill in the connection details:
Name: WISK
Description: Inventory, invoices, ordering and sales data from WISK
MCP Server URL:
https://mcp.wisk.ai/mcp
For authentication, choose OAuth.
Click Scan tools so ChatGPT can read WISK's available tools, then click Create.
Step 3 — Sign in to WISK and choose the level of access
When you connect, a WISK sign-in page opens in your browser.
Sign in with your WISK email and password.
Read the notice. WISK tells you it has not verified the app that is asking for access, and shows the web address your access will be sent to. Check it, and continue only if you started this connection yourself.
Check the level of access. Connections are read-only: ChatGPT can look at your data and answer questions, but cannot change anything in WISK.
Click Approve. You are sent back to ChatGPT and the connection is ready.
Step 4 — Ask WISK something in ChatGPT
Start a new chat, click the + button, choose the WISK app (or @mention it), and ask a question — for example, "What's my current stock of Grey Goose?"
Try:
"What's my current stock of Tito's at the Main Street location?"
"What did my last invoice from Southern Glazer's include, and did any prices go up?"
"What should I order this week based on my par levels?"
"How did last weekend's sales compare to the weekend before?"
If you have more than one venue, name it in your question — one connection covers every venue your WISK account can access.
What ChatGPT can and cannot see
ChatGPT gets exactly what your WISK account gets: the venues you are assigned to, and only what your WISK role allows. It cannot reach another venue, another user's data, or anything your permissions hide from you.
One connection covers every venue you have access to. You do not need to connect once per venue.
The connection is read-only: ChatGPT can never edit items, counts, orders or invoices.
Revoking access
You can cut ChatGPT off at any moment, from either side:
In WISK:
Hover over your user name and click "Account" then OAuth2 Apps
Find the entry for this connection and click Disconnect. Access stops immediately
In ChatGPT: Go to Settings → Apps, find WISK and remove it. On Enterprise/Edu plans, a workspace admin can also disable it for everyone from Workspace Settings.
Troubleshooting
I don't see Developer Mode or an Apps option in Settings.
Custom MCP connectors currently require a ChatGPT Business, Enterprise, or Edu plan, and Developer Mode has to be turned on for your account by an admin (or by you, if you are one). It is not available on Free, Plus or Pro plans.
"Scan tools" fails or times out when adding WISK.
Double-check the server URL is exactly https://mcp.wisk.ai/mcp, then try again.
The sign-in window doesn't appear or fails.
Pop-up blockers can stop the WISK sign-in page from opening — allow pop-ups for ChatGPT and try connecting again. If your WISK password isn't accepted, reset it at web.wisk.ai first, then retry.
ChatGPT answers without using WISK data.
Make sure the WISK app is selected (or @mentioned) for that chat, and that a workspace admin hasn't disabled it. Asking a specific question that names an item or venue usually helps ChatGPT pick the right tool.
