Request for early access to MCP App publishing (fully working app)

GPT builders

1

Hi,

I’ve built a fully functional ChatGPT App using a custom MCP server hosted at:

https://mcp.guiaturist.com

The app is already working end-to-end inside ChatGPT (DEV mode) and includes:

  • OAuth authentication via Auth0 (RS256 JWT validation)
  • MCP tools (search_restaurants)
  • Interactive UI widget rendered inside ChatGPT
  • NLP-based query interpretation (e.g. “where to eat ceviche” → category mapping)
  • MongoDB backend with real restaurant data

Full flow:
User → Widget → MCP → NLP → MongoDB → structured results → ChatGPT UI

The application is deployed on a public domain and fully operational.

I’m currently using ChatGPT Plus and would like to request early access to the app publishing / review flow to submit it to the directory.

Happy to provide a demo or any additional details if needed.

Thanks!

Example of the app running inside ChatGPT (DEV mode).

First image shows successful restaurant results retrieved from MongoDB after NLP-based query interpretation.
Second image shows the fallback case when no results are found.

Adding a quick demo of the app running inside ChatGPT (DEV mode).

Example flow:

  • User selects country and city
  • Enters a query like “where to eat ceviche”
  • Backend infers category via NLP
  • MongoDB returns matching restaurants
  • Results are rendered in the ChatGPT widget

Happy to provide live demo access if needed.

Thanks for your interest!

The app is designed to run inside ChatGPT using MCP, not directly via browser.

You can test it by connecting it as a custom app in ChatGPT:

  1. Go to ChatGPT → Settings → Applications

  2. Click “Create” (or add a custom app)

  3. Use this MCP endpoint:
    https : // mcp. guiaturist. com / mcp (I can’t post the link.)

  4. Connect the app

During connection, OAuth (Auth0) will trigger automatically.
You can sign in using your Google account (recommended).

Once connected:

Then start a new chat, click +, select the connection, type “open guiaturist” and the wizard will appear.

  • Select country and city
  • Enter a query like “donde comer un ceviche ”
  • The backend will process the request (NLP → MongoDB) and return results in the widget

Let me know if you have any issues setting it up, happy to help.

Looking forward to your feedback!
