Show HN: I Built and Ran an AI Wedding Concierge at My Own 300-Person Wedding

Summary

The creator, an American who married a Mauritian, built and operated an AI guest concierge for their Hindu wedding in Mauritius. Because family and friends were unfamiliar with both Hindu wedding customs and the island, he expected to spend substantial time answering questions while preparing the event. The couple arrived only two weeks before the wedding, increasing the need for a self-service source of information. He created a wedding database containing their event details, connected it to an MCP server with tools, attached an AI agent, and distributed an invitation link to guests. As the project expanded, it became a broader platform for wedding planning as well as guest support. The creator says the two functions are closely connected because reliable answers require a well-maintained knowledge base, and the planning tools naturally provide that information structure. The demo presents an example wedding in which visitors can act as guests and interact with the concierge. He also reports that the most common activity among guests on the ceremony day was attempting to jailbreak the AI, illustrating an unexpected way people used the system.
