ChatGPT
OpenAI ships two separate tools, and each is connected on its own: add a direct MCP connection in ChatGPT, or install the Judaro plugin in Codex.
In ChatGPT, Judaro is added as a direct MCP connection. You set it up once on the web and it is saved to your account; the Judaro plugin is not installed.
1. Open the sidebar, then Plugins
Go to chatgpt.com. If the sidebar is collapsed, click the expand handle at its edge. In the open sidebar, select Plugins, then click the add button next to Search. You can also open the screen directly at chatgpt.com/plugins.
Go to chatgpt.com and follow the sequence above. Direct shortcut: chatgpt.com/plugins.
Click the add button next to Search.
The dialog is titled New Plugin in the ChatGPT interface, but this flow adds a custom MCP server directly. In the Name field type Judaro.
In the Connection row, in Server URL mode, paste the address.
https://mcp.judaro.com/mcpUnder Authentication keep OAuth.
Leave Advanced OAuth settings unchanged, tick I understand and want to continue, and click Create.
In the Add Judaro to ChatGPT dialog click Sign in with Judaro and sign in with your registered email.
That is it. The Judaro connection is available in every new chat. ChatGPT may list it under Installed.
Verify your Judaro account
After Sign in with Judaro, authenticate with Google, Microsoft, or an email verification code. Use the email address registered for your Judaro access, then return to ChatGPT.
Try it in ChatGPT
Each arrow opens a new ChatGPT chat with the prompt prefilled. You still decide when to send it.
No Plugins entry in the sidebar, or no plus button? On some accounts you first flip Developer mode on once, under Settings then Apps then Advanced settings. On an organization account the workspace admin may need to allow it.
Codex is a separate tool from ChatGPT. Install the Judaro plugin from its personal marketplace; settings do not carry over from ChatGPT.
Open the Codex app and select Plugins in the sidebar.
Click Add, then choose Add marketplace.
Name the marketplace Judaro, paste
https://github.com/ai4laws/judaro-plugin, and click Add marketplace.Switch to the Personal tab and open the Judaro marketplace.
Click Install and wait until the button shows Installed.
To select Judaro explicitly, type @judaro in a new task and choose Judaro from the list.
On first use, a browser opens. Sign in to Judaro with your registered email, then return to Codex.
The plugin configures the Judaro MCP connection for Codex; you do not need to paste the MCP server URL separately.
If something does not work
- No Plugins entry: update the Codex app.
- The marketplace cannot be added: make sure git is installed and copy the full repository URL.
- Judaro does not appear: open a new task after installation.
- Answers have no access: sign in again with your registered email address.

To check it works: open a new chat and ask "Which legal domains do I have in Judaro?". If a list of domains comes back, you are done.
