Home Memory

Ask your home.

Your AI assistant's memory for everything in and around your home.

Home Memory is an MCP server that gives your AI assistant structured, persistent knowledge about your home: every room, every device, every pipe and cable, every item you own.

It works with the ChatGPT desktop app, Claude Desktop, Claude Code, Codex CLI, and other MCP-compatible AI apps. You talk naturally; the AI reads and writes your home data through Home Memory's tools.

Document what exists, plan what's coming, and keep track of what's been removed.

No app to learn. No forms to fill out. Your home data stays in a single file on your machine, and the AI is your interface.

Tell your AI about your heat pump, your car, your power tools, or your wine collection, and it extracts the relevant details and stores them as structured data in your local database. Snap a photo of a device or hand it an invoice. Same result. Ask "What's in the basement?" or "When is my car due for inspection?" and get answers from real data.

What you can do

Document anything by just talking:

"I have a Daikin Altherma heat pump in the utility room."

Your AI finds the right category, resolves the location, and creates the element. No manual data entry.

"My car is a 2023 Toyota Corolla Hybrid, next inspection is due in March."

Not just building infrastructure: vehicles, tools, appliances, valuables, anything that belongs to you.

Ask questions about your home:

"What's in the basement?" · "Show me all planned purchases." · "Where is my washing machine?"

Upload a photo and let your AI identify it:

(attach a photo of a device) "What is this? Add it to the utility room."

Vision-capable AIs recognize the device and create the element via MCP.

Read an invoice and extract devices:

(attach a PDF invoice) "Extract the installed devices and add them to my home."

Track connections between elements:

"The circuit breaker panel feeds the kitchen outlet via NYM-J 3x1.5."

Cable routes, pipe runs, duct paths, all documented as connections between elements.

Plan renovations:

"We're planning a PV system on the roof." · "The old oil heater was removed last year."

Track what's planned, what exists, and what's been removed.

Quick Start (Windows)

The release ZIP is self-contained. No .NET or Firebird installation is required. You need one of the local AI clients listed below.

Set up with your local AI

Already use Codex or Claude Code locally on your Windows PC? It can help install and configure Home Memory. Paste this prompt:

Set up Home Memory from https://github.com/impactjo/home-memory on this Windows PC. Follow its README and Setup Guide, use the latest official release ZIP, and register it with the local AI client I am currently using. First check whether Home Memory is already installed or registered. Preserve existing client configuration and any existing Home Memory database, and update an existing registration instead of creating a duplicate. If the downloaded release contains skills\home-memory-documentation and this client supports Agent Skills, install that directory as a user-level skill. Make sure any installed skill files come from the downloaded release, not from an existing development copy. If the release does not contain the directory, complete the MCP setup without it and report that the optional documentation skill was not installed. Ask for explicit confirmation before replacing an existing installation or migrating a database. Verify the MCP connection after registration. Tell me whether the server and documentation skill were installed, and whether I need to restart the client or start a new session.

The MCP server gives your AI access to the local Home Memory database. The optional documentation skill adds rules for structuring that documentation. If the release ZIP contains skills\home-memory-documentation, that directory can be installed as a user-level skill. Clients without Agent Skills, or older releases without that directory, can still use the MCP server.

To install the skill separately, ask a client that supports Agent Skills to install skills/home-memory-documentation from this repository as a user-level skill.

After registration, continue with 3. Try it to verify the connection.

Prefer to set it up yourself? Continue with 1. Download & Extract below.

1. Download & Extract

1. Download the latest release ZIP from GitHub Releases
2. Extract to a folder, e.g. C:\HomeMemory\

2. Connect to your AI

Choose one of the following clients and use a local session on the computer where you extracted Home Memory. A cloud session does not automatically have access to this installation. For phone access to the same computer, see 4. Use it from your phone below.

codex mcp add home-memory -- "C:\HomeMemory\HomeMemoryMCP.exe"

{
  "mcpServers": {
    "home-memory": {
      "command": "C:\\HomeMemory\\HomeMemoryMCP.exe"
    }
  }
}

claude mcp add home-memory --scope user -- "C:\HomeMemory\HomeMemoryMCP.exe"

3. Try it

On first launch, Home Memory automatically creates a local database with over 100 categories and an initial example structure (floors, rooms, garage, outdoor areas). No setup wizard needed.

First, verify that your AI can use Home Memory:

"Use the Home Memory MCP tool get_structure_overview to show me the structure currently stored in Home Memory. If the tool is unavailable, tell me instead of guessing."

You should see the initial example structure, including a ground floor, upper floor, basement, and several rooms. This confirms that your client can discover and call Home Memory's tools.

If Home Memory is unavailable or reports an error, see Troubleshooting.

Once this works, you normally do not need to mention Home Memory or individual tool names. Continue naturally:

"I have a Bosch washing machine in the basement."

Your AI creates the element, finds the right category, and places it in the basement, all in one step. Ask "What's in the basement?" to verify.

"We're planning to install a heat pump in the utility room."

Creates a planned element, so you can track what exists and what's coming.

If it works, setup is complete. From here, you can work with your AI in natural language to adapt the example structure, add appliances, furniture, or tools, and capture details from photos or invoices.

4. Use it from your phone (optional)

Home Memory runs locally, but you can use it from your phone through remote access in Claude Code or the ChatGPT desktop app. In both cases your Home Memory database and MCP server stay on your machine; the phone is just a remote window into a session running on that host.

Handy whenever you are away from your computer and want to look something up or capture it on the spot, whether at the fuse box, out in the garden, or snapping a photo of a new appliance.

• Claude Code: start a local session, enable Remote Control, then continue it from the Claude mobile app or claude.ai/code. Requires a signed-in Claude account.
• ChatGPT desktop app: start Remote setup on your host machine, then pair your phone by scanning the displayed QR code with the ChatGPT mobile app.

Build from Source (advanced)

See Building from Source in the Setup Guide for prerequisites, build commands, and Firebird configuration.

How it works

You ──── AI Assistant ──── Home Memory MCP ──── Local Database
(natural language)           (24 tools)    (Firebird, single file)

Home Memory implements the Model Context Protocol (MCP), an open standard that lets AI assistants use external tools. When you talk to your AI about your home, it calls Home Memory's tools behind the scenes to read, create, update, and search your home data.

Your data stays local. The database is a single file on your machine. Nothing is sent anywhere except to the AI you're already talking to.

Features

24 MCP Tools

Covers every domain, fully customizable to your needs

Electrical (circuits, PV, wallbox, home automation) · HVAC · Plumbing · IT & Communications · Security (alarm, fire, surveillance) · Building Materials · Landscaping (garden, pool, irrigation) · Household (appliances, furniture, valuables) · Vehicles · Tools · Health · Sports & Leisure

Every category, every element, every status is editable. Rename, add, or remove anything to match how you think about your home.

Smart defaults

• Over 100 categories organized by trade and domain, from circuit breakers to garden sprinklers to vehicles
• Default house structure with floors, rooms, garage, and outdoor areas, customizable by talking to your AI
• Auto-setup on first run, no manual database creation needed
• Flexible naming: your AI can use "Ground Floor" or "GF", the server resolves both

Compatibility

The release ZIP is a self-contained Windows build with all dependencies included (no .NET or Firebird installation required). On macOS and Linux, you can build from source with .NET 10 and Firebird 3; see the Setup Guide for details.

Configuration

HTTP mode (LAN, optional)

Stdio is the default and works for almost everyone. HTTP mode lets you run Home Memory as a persistent service on a NAS, homelab box, or another machine on your LAN. See docs/HTTP-MODE.md for setup, database locking, LAN access, and HTTP security requirements.

Architecture

• .NET 10 with ModelContextProtocol SDK
• Firebird Embedded: local database engine, single-file storage
