MCP server for home inventory memory

Home Memory plugs into MCP-compatible assistants so you can talk naturally about your house and have the assistant create, update, and search structured records. It keeps the data local in a Firebird database and exposes tools for elements, connections, categories, and status.

Who it's for

Builders who want their MCP-compatible assistant to keep track of rooms, devices, repairs, and planned changes around a home.

What it delivers

You can ask your assistant what exists, what is planned, and where things are without rebuilding the home inventory by hand.

What it does

Home structure search and browse

Tools like `get_structure_overview`, `find_element`, `list_elements`, and `get_element_details` let your assistant explore the home inventory.

Create and update home records

Tools for `create_element`, `update_element`, `delete_element`, and `move_element` let the assistant add or change rooms, devices, furniture, and fixtures.

Track physical connections

Connection tools record cables, pipes, ducts, and other links between elements.

Manage editable categories and statuses

Built-in tools manage over 100 categories and status values for existing, planned, and removed items.

Local single-file storage

The server keeps data in a local Firebird database file on your machine.

How to get it

  1. 1Or via Codex CLI
    codex mcp add home-memory -- "C:\HomeMemory\HomeMemoryMCP.exe"
  2. 2Home Memory is available in both the Chat tab and the Code tab. The Code tab is…
    claude mcp add home-memory --scope user -- "C:\HomeMemory\HomeMemoryMCP.exe"
  3. 3Requires .NET 10 SDK and Firebird 3.0.

Home Memory: Your home holds more than you remember.
Prefer a less technical introduction? Visit home-memory.com.


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.

Demo in Claude Desktop: One sentence creates two elements. The AI finds the right categories, creates a missing room, and documents everything.

Demo with Codex: Same prompt, same result, works across AI clients.
Codex (OpenAI)

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, no Firebird, no other software to install.

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:

ChatGPT desktop app (Codex)
  1. Open the ChatGPT desktop app and select Codex
  2. Open Settings
  3. Select Plugins in the navigation, then open the MCPs tab
  4. Click + Add server
  5. Name: home-memory
  6. Command to launch: C:\HomeMemory\HomeMemoryMCP.exe
  7. Leave transport on STDIO (default)
  8. Click Save, then restart the app if needed

Or via Codex CLI:

codex mcp add home-memory -- "C:\HomeMemory\HomeMemoryMCP.exe"
Claude Desktop
  1. Open Claude Desktop
  2. Click the Claude menuSettingsDeveloperEdit Config
  3. This opens the config folder with claude_desktop_config.json selected. Open it in any text editor
  4. Add home-memory inside the "mcpServers" object:
{
  "mcpServers": {
    "home-memory": {
      "command": "C:\\HomeMemory\\HomeMemoryMCP.exe"
    }
  }
}

If you already have other MCP servers configured, add the "home-memory" entry next to them inside the existing "mcpServers" block.

  1. Save the file and restart Claude Desktop

Home Memory is available in both the Chat tab and the Code tab. The Code tab is recommended for multi-step, agentic workflows that use several MCP tools.

Claude Code (CLI)
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 a default house structure (floors, rooms, garage, outdoor areas). No setup wizard needed.

Try these prompts in order:

"Show me the structure of my home."

You should see your default house structure: ground floor, upper floor, basement, each with rooms. This confirms everything is working.

"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, you're done. Everything from here is just talking to your AI. Add rooms, rename floors, document your electrical panel, upload a photo of a device. The AI handles the rest.

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)

Requires .NET 10 SDK and Firebird 3.0.

git clone https://github.com/impactjo/home-memory.git
cd home-memory
dotnet publish HomeMemoryMCP -c Release

See Setup Guide for details on Firebird configuration and environment variables.

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.

Contributing

Home Memory is early-stage. Feedback is welcome. Right now, the best way to contribute is:

  • Open an issue for bug reports, feature ideas, or questions
  • Share your use case: how are you using Home Memory? What's missing?
  • Spread the word if you find it useful

If you'd like to build and explore the code locally, see the Setup Guide.

Background

Home Memory builds on a proven data model from Smartconstruct, a desktop application for documenting physical assets, refined through real-world use in residential construction projects.
