Anyone who's tried to remember which circuit breaker controls the kitchen outlet, or what paint code was used in the bathroom, knows the problem. Home Memory, a new open-source MCP server from developer impactjo, gives your AI assistant a structured database of your entire home. You tell Claude or Codex "I have a Daikin Altherma heat pump in the utility room" and it handles the rest. The system ships with over 100 built-in categories covering electrical systems, plumbing, HVAC, vehicles, tools, and more, all stored locally in a single file on your machine.
The tool offers 22 MCP actions (9 read, 13 write) that let AI assistants create, search, update, and connect elements. You can snap a photo of a device and have a vision-capable AI identify and catalog it. You can upload an invoice and have installed equipment extracted automatically. Physical connections between elements, like cable routes, pipe runs, and duct paths, are tracked as relationships. When you're renovating or troubleshooting something behind drywall, that wiring matters.
impactjo previously built Smartconstruct, a commercial Windows application for documenting buildings and facilities. Home Memory takes that same Firebird database architecture and swaps the manual GUI for an AI-driven interface via the Model Context Protocol. The friction reduction is real. Tools like the Travel Hacking Toolkit are designed to remove that friction. Instead of clicking through forms, you just talk.
The project is Windows-only for now, distributed as a self-contained .NET 10 executable under AGPL-3.0 licensing. If you've ever knocked on drywall wondering which way the conduit runs, you get why this exists.
