title="<h2>Gradio MCP Hackathon: fake-app-scraper</h2>"
description="""<div style="font-family: sans-serif; line-height: 1.6;">
  <p>
    This app uses Playwright to log in and scrape the content of the dashboard of the fake app
    <a href="https://fake-app-omega.vercel.app" target="_blank">fake-app-omega.vercel.app</a>.
  </p>    
  <p>
    The starting point was to provide an LLM-friendly, API-fied version of a real app that does not provide any API. Used as an MCP server, any user of the app could simply ask their AI assistant to fetch information from their dashboard.
  </p>
  <h3>Problem</h3>
  <p>
    When run locally, the app can take the credentials as environment variables to log into the user's dashboard. However, when hosted as a Hugging Face Space, I couldn't find a way to send the credentials securely—i.e., without explicitly providing them to the LLM.
  </p>
  <p>
    In conclusion, as it stands, this app together with the fake Next.js app only serves demonstration or educational purposes and does not solve a real-life problem.
  </p>
  <p><strong>I’d be happy to get any suggestions on how to send credentials in the context of a Gradio HF Space–hosted app.</strong></p>
