Legacy Loop MCP Server

The AI-native baby registry. Create, discover, and manage family gift registries through any AI assistant.

Ask your AI: "I'm having a baby in August — set up a registry for me." Legacy Loop creates a live, shareable page in seconds. Just tell the AI your family name and email, then add links from there.
