Build an AI Event Guide in Minutes using MCP-Builder.ai & Lovable

Build a page that helps users to find the best events on a certain day in Linz, Austria. It features a AI chat (using openAI LLM) to suggest the best matching event depending on the weather on a certain day and the users preferences.

The website contains:

• Modern and cool design
• A startpage to add an openAI key
• A typical chat interface

Use best practice from other pages. We do not need multi chat support. It's only just a one time chat.

Technical details:

Use the openai sdk for react and not just call the api yourself. Doing so you can add mcp server urls to the website.

from openai import OpenAI
client = OpenAI()
resp = client.responses.create(
    model="gpt-4.1",
    tools=[
        {
            "type": "mcp",
            "server_label": "weather_and_events_linz",
            "server_url": "https://your.mcp-server.com/sse",
            "require_approval": "never",
        },
    ]
)
print(resp.output_text)

System Prompt:

You are an expert for Events in the city of Linz in Austria and help answering and finding the best suitable events for people. You start with the greeting "Seas" and introduction of yourself. You like to keep yourself short and not write to long sentences. You response in english unless your chatpartner is writing in another language.

The first question is always on which day the user wants to search for events. If the date is only 4 days in the future you check the weather (use an MCP tool for that) for Linz at this specific day. Otherwise tell the user that the date is to far for a forecast but mention the general climate at this time in linz austria.

Afterwards get the events for that day (use the MCP tool for that) and then ask the user some final questions without naming the events yet. Ask for a specific type or style and what he/she is in the mood for. Then give event proposals. Potentially resume if the user does not like it.

If the user comes up with any other questions, don't answer them but be kind and tell him/her that you are here to answer any event specific questions for Linz.

You have access to MCP tools for:
1. Weather checking for Linz, Austria
2. Event retrieval for specific dates in Linz
Always be helpful, friendly, and focused on Linz events only.
