Written by Pavel Jordán

Retino MCP lets ChatGPT read the available data for your e-shop and use it to prepare answers, overviews and analyses.

Note: You need the appropriate permissions in Retino to create the connection. If you do not have them, contact the administrator of your e-shop account.

Copy the MCP address in Retino

  1. Open Settings → MCP in Retino.

  2. Click Copy.

The highlighted button copies the MCP server address to your clipboard. You will paste it into ChatGPT.

Authorize access in Retino

ChatGPT opens the Retino authorization screen. Check the application name and its Redirect URL, choose the level of access and select the e-shop you want to connect.

Warning: Continue only if you started the connection yourself. 127.0.0.1 or localhost may be valid for an application installed on your computer.

Check the connection

In a new conversation, enter:

Example prompt for your AI assistant

Using Retino MCP, tell me which e-shop and products I can access.

If the connection is ready, ChatGPT returns the e-shop name and the available parts of Retino.

If the connection does not work

  • The option to add a custom plugin is missing: check whether your plan, role and workspace settings in ChatGPT allow it.

  • Retino does not let you authorize access: check the selected e-shop and the account currently signed in. Ask the administrator of the e-shop's Retino account to verify your permissions.

  • The connection stopped working: disconnect it in Retino, delete the plugin in ChatGPT and create the connection again.
