Connecting FazerCards to ChatGPT
ChatGPT can work with your FazerCards catalog, orders and balance through a custom connector, but your account has to clear three gates first: a paid plan, a desktop browser, and developer mode. Check those before you touch any settings. After the connector is saved you still have one habit to learn, because ChatGPT does not switch the app on by itself.
Before you start
- A paid ChatGPT plan: Plus, Pro, Business, Enterprise or Education. Free accounts cannot add a custom connector at all.
- A desktop web browser. The iOS and Android apps have no way to add one, even on a paid plan.
- Developer mode turned on in ChatGPT settings.
- On Business, Enterprise and Education, a workspace admin may have to allow developer mode before you can see it.
- Your FazerCards connection link, taken from the panel: profile page -> the "Connect to AI" card.
Why there is nowhere to put a key
The ChatGPT connector form asks for exactly three things: a name, a server URL, and an authentication choice. That is the entire form. No header editor, no API-key box, no separate secret store.
That is why the FazerCards address carries your token inside the path. You paste the full link ending in /mcp/mcp_... and select the option that means no authentication, leaving any OAuth fields untouched. A bare https://api.fzr.cards/mcp with nothing after it identifies no account and will connect to nothing. The rules about the token itself, revoking it, and what an order costs you are the same in every client and are covered on the MCP hub page.
Developer mode is a moving target
OpenAI has relocated this switch more than once. Depending on which release your account is on, it has appeared under Connectors, under Apps & Connectors, and under Security and login.
So do not follow a menu path from memory or from a forum post. Open ChatGPT settings and hunt for the word "Developer" - your browser's find-in-page across the settings panes is the fastest way. If the word appears nowhere and you are on a paid personal plan, the switch is usually one release away or one pane over; if you are on a workspace plan, it is more likely that an admin has not enabled it.
The app is per conversation, not per account
This is the single most common "it stopped working" report, and it is not a fault. Saving the connector makes FazerCards available to ChatGPT; it does not put it into any particular chat.
In every conversation where you want it, open the "+" menu in the message composer and select the FazerCards app. A brand-new chat always starts without it, including the chat you open tomorrow morning out of habit. You can tell it is live when a request produces a visible tool-call card rather than a plain written answer - if ChatGPT replies conversationally and mentions no lookup, the app is off for that chat and anything it says about prices or stock is invented.
What the risk notice and the scan are
When you add any custom connector, ChatGPT shows a risk acknowledgement and runs an automated safety check against the server before the connector becomes usable. This is a platform-level step applied to every third-party MCP server, not something specific to FazerCards.
Expect a short pause on save. If the connector lands in the list and can be selected in the composer, the check passed. Re-adding the same server later runs it again.
Step by step
Confirm you are eligible
Verify your plan is Plus, Pro, Business, Enterprise or Education, and that you are on a desktop browser rather than a phone. If either is not true, stop here - no setting will unlock the connector form.
Copy your connection link from FazerCards
Open your FazerCards panel, go to the profile page and find the "Connect to AI" card. Generate the link and copy it whole. It looks like https://api.fzr.cards/mcp/mcp_... - the part after the last slash is what identifies your account.
Turn on developer mode
In ChatGPT settings, search the panes for the word "Developer" (it has lived under Connectors, Apps & Connectors, and Security and login in different releases) and enable it. Reload the page afterwards so the connector controls appear.
Open the connectors page and start a new one
Go to chatgpt.com/plugins and press the "+" button to create a custom connector.
Fill in the three fields
Name it FazerCards, paste your full connection link as the server URL, and choose the authentication option that means none (labelled "No authentication" or similar). Leave every OAuth field empty - there is no field for a key or a header, and none is needed.
Accept the notice and let the scan finish
Tick the risk acknowledgement and save. Wait for the automated safety check to complete; the connector appears in your list when it is done.
Switch the app on inside the chat
Open a conversation, click "+" in the message composer and select FazerCards. Repeat this in every new conversation - it is never automatic.
Confirm it is actually attached
Ask something that can only be answered by looking, such as your current balance. A working setup shows a tool-call card in the reply. If you get a written answer with no tool card, the app is not selected in that chat - go back to the "+" menu.
Configuration
https://api.fzr.cards/mcp/mcp_your_token_hereIf something goes wrong
There is no "Developer" wording anywhere in ChatGPT settings.
Reload the page and search each settings pane by hand; the switch has moved between releases. On a workspace plan, ask your admin to allow developer mode.
chatgpt.com/plugins shows no "+" button, or the page is unavailable.
You are almost certainly on the Free plan or in a mobile browser. Custom connectors need a paid plan on desktop.
The connector saved fine, but ChatGPT answers about stock and prices without ever looking anything up.
The app is not selected in that conversation. Open "+" in the composer and pick FazerCards, then ask again.
Everything worked yesterday; today the same question gets a vague answer.
You are in a new chat. Selection does not carry over between conversations.
The connector is added but every action errors out.
The URL was probably pasted short. Re-copy it from the panel and check it ends with /mcp/mcp_... rather than /mcp.
Questions
I am on a paid plan but I cannot find developer mode. Where is it?
There is no stable answer, which is why we tell you to hunt rather than follow a path. OpenAI has placed it under Connectors, under Apps & Connectors, and under Security and login in different releases. Open settings and search for the word "Developer" pane by pane. If it is genuinely absent on a personal paid plan, your account has not received that release yet.
Can I set this up from the ChatGPT app on my phone?
No. Adding a custom connector is a desktop web browser feature only; the mobile apps have no equivalent screen. Do the setup once on a computer. Whether the connector is then usable on mobile depends on your ChatGPT release, but the setup itself cannot be done there.
Why do I have to select FazerCards in every new conversation?
Because ChatGPT scopes apps to the conversation, not the account. Adding the connector makes it available; the "+" menu in the composer is what attaches it to the chat you are in. Every fresh chat starts clean, and this is the number one reason people believe the connection has broken.
What is the risk warning and the scan that appeared when I saved?
ChatGPT asks you to acknowledge that you are adding a third-party server, then runs an automated safety check against it before enabling the connector. It applies to every custom MCP server on the platform. If the connector shows up in your list and can be picked in the composer, it passed.
My company account has developer mode greyed out or missing.
On Business, Enterprise and Education workspaces the capability is administered centrally. A workspace admin has to allow developer mode before individual members can create custom connectors. There is no way around it from your own settings.
Where do I enter my token or an API key? The form has no field for it.
It has none by design - the ChatGPT form only offers a name, a server URL and an authentication choice. Your token travels inside the server URL, which is why the address you paste ends in /mcp/mcp_... Pick the no-authentication option and leave OAuth fields empty.
