Show HN: Home Memory – A local DB of my house, down to cables and pipes

I’m curious how different is it compared to use an AI agent to get your transcript, summarize and document it a file, and then ask it something? Like a simple RAG or even just project in codex

I've been documenting my house in software for years: outlets, conduits, circuits, pipe runs, appliances, vehicles. Having that data came in handy more often than I expected. But adding data was always the bottleneck. Opening the app, navigating to the right room, picking categories, filling in fields.

So I built an MCP server for that database. Now Claude, Codex, and other MCP-compatible clients can read and write the home data directly. Tell it about a heat pump in one sentence, or snap a photo of the nameplate, and it figures out the category and location. Later you can ask whether it's worth repairing given its age.

It also tracks physical connections between elements: cables, pipes, ducts, and where they run. The database is a single local file on your machine.
