1. Open Plugins
Click the button and ChatGPT's Plugins screen opens.
2. Choose Add custom MCP server
Only Create plugin and Upload plugin archive in the menu? Your account has not received the ChatGPT update yet. In that case turn on Developer mode once on the Security and login screen, refresh and open Add again. On an organization account the workspace admin may need to allow it first.
3. Fill in the details and create
The Add custom MCP server dialog opens. This adds an MCP server directly; it does not install the Judaro plugin. In Name type Judaro, keep Connection on Server URL, paste the address https://mcp.judaro.com/mcp, and under Authentication keep OAuth. Leave Advanced OAuth settings as they are. Finally tick I understand and want to continue and click Create as a plugin.
4. Connect to Judaro and sign in
In the Add Judaro to ChatGPT dialog click Sign in with Judaro. ChatGPT opens the Judaro sign-in screen in your browser.
Sign in with Google, with Microsoft, or get a verification code by email. Finish signing in and you are back in ChatGPT. Always use the email you registered with.
Important. With a different email the sign-in may go through, but the answers will come back without access.
5. Try it
Open a new chat and pick one of the openers. If a list of domains comes back, the connection works.
That’s it. Judaro is added to your account and available in every new chat. ChatGPT may list it under Installed.
If something doesn’t work
No Add custom MCP server in the Add menu
Your account has not received the ChatGPT update yet. Open Plugins with the settings, turn on Developer mode once and refresh. On an organization account the admin may need to allow it.
Create as a plugin stays greyed out
Check that the address is complete, that Authentication is set to OAuth, and that the confirmation box is ticked.
Judaro does not show up after adding it
Open a new chat; connections do not always load into a chat that is already open.
Answers come back without access
Almost always you signed in with a different email than the one you registered with. Sign out and sign in again with your registered email.
