The Claude or ChatGPT connection is not working

Let us find the problem. Which of these is happening?

1. Claude answers but does not use Cadabra. Click the plus next to the message box and check Cadabra is ticked. Starting with "In Cadabra, make me..." helps too.

2. ChatGPT does not see Cadabra. In ChatGPT you pick it again in every chat: the plus, then Cadabra.

3. Reconnect shows next to Cadabra. Click it and allow again on Cadabra's screen. Credits and gallery are untouched.

4. No Create MCP App in ChatGPT. You need a paid plan and chatgpt.com in a computer browser, not the app. The button is on the Plugins page in the side menu, not in Settings.

5. You pressed the button, Claude opened, but no window. You were probably not signed in to Claude. Sign in and press again.

6. You attached an image in Claude and it ignores it. Upload it on Cadabra's upload page and paste the link you get into the chat.

Still stuck? Tell me exactly what you see on the screen.
