Adding the Zuzli plugin to ChatGPT manually

Part 1 · Enable developer mode in ChatGPT

1. 1

   Open ChatGPT on desktop

   These settings are available in the browser or desktop app.

2. 2

   Go to Settings

   Click your avatar, then Settings.

   
3. 3

   Open Security and login

   In the settings sidebar.

4. 4

   Turn on Developer mode

   Scroll to Developer mode and flip the toggle on. This is what allows adding a custom MCP server.

   

Part 2 · Add the Zuzli connector

1. 1

   Go to the Plugins tab

   Click the + button now available at the edge of the screen to add a connector manually.

   
2. 2

   Fill in the MCP server details

   Server name:

   Zuzli

   Server URL:

   https://zuzli.app/mcp

   Leave Authentication on OAuth.

   And don’t forget to check the risk acknowledgement below — it’s only there because this is Dev mode. Later we’ll ship from the OpenAI plugin store and you won’t need all these scary warnings :-)

   Click Create to continue.

   
3. 3

   Sign in to Zuzli

   A Zuzli sign-in window opens. Approve access and Zuzli appears in your connector list.

   

   

Part 3 · Install the Zuzli planning skill

The connector lets ChatGPT read and update trips. The skill teaches it to plan the Zuzli way: in Hebrew, in geographic order, with realistic timing, tips and real content for every stop. We recommend installing both.

1. 1

   Download the file

   Save plan-with-zuzli.zip to your computer. Do not unzip it.

   Download the skillZIP file · plan-with-zuzli · latest version
2. 2

   Go to the Skills screen

   On the Plugins screen, open the Skills tab and click the add button on the right.

   Note: at this stage a Pro account (or higher) is required to add skills manually. Once Zuzli is available from the plugin store, full use including skills will work from a free account as well.

   
3. 3

   Upload the ZIP

   Choose Upload from your computer, then pick the Zip file you just downloaded. After the upload finishes and a green check appears, close the dialog to return to the Skills screen.

   
4. 4

   Confirm it is installed

   plan-with-zuzli appears in the installed skills list.

   

Part 4 · Your first chat

1. 1

   Open a new chat under Work

   The chat must be in Work mode, not a regular chat, to use the skill we added. Once we ship from the official plugin store, regular chat will work too — including without a Pro account.

   
2. 2

   Prepare the prompt

   To talk with Zuzli, start the chat by connecting the plugin — type:

   @Zuzli

   Then pick the plugin from the list that appears.

   Right after that, add the Skill the same way — type:

   @plan-with-zuzli

   and select the Skill.

   
3. 3

   Now plan the trip!

   Right after adding the plugin and the skill, you can continue and plan your first trip. For example:

   אני מתכנן טיול ל3 ימים לרומא עם הילדים שבוע הבא, עזור לי לבנות את הטיול המושלם
4. 4

   And you’re ready for Zuzli!

   Zuzli will ask relevant questions and build a full trip straight into the app. You can always continue in the same Work chat or open a new one, ask about your trips, and make changes in real time.
