Homey-Wan-Kenobi MCP

MCP server for controlling Homey Pro smart home systems through the Model Context Protocol.

The name nods to Obi-Wan Kenobi, your home's only hope for natural-language control.

60 tools and 3 knowledge prompts for device control, flow authoring, automation, monitoring, troubleshooting, network diagnostics, and self-hosted deployment.

Why Homey-Wan-Kenobi

Athom ships an official Homey MCP Server: a cloud-brokered remote connector you add to a paid Claude or ChatGPT plan and sign into with your Homey account. It covers device status and control, renaming and moving devices, creating, updating and starting Flows and Advanced Flows, and setting Moods.

This server differs in two ways. It is self-hosted, so you run it yourself over stdio or streamable-HTTP with no third-party broker and no paid AI-plan requirement. And it adds operational depth for power users that is not part of the official server's described capabilities.

The table reflects Athom's publicly described capabilities as of June 2026. Athom does not publish a formal tool list, so the right-hand gaps are inferred from their documentation, not stated by Athom.

The depth, in practice

• Network diagnostics that the official server does not describe. diagnose_zwave_network and diagnose_zigbee_network read controller health, grade each node by last-seen age (battery-sleep aware), group transmit failures, correlate them with unavailable devices, and return severity-ranked remediations. get_zwave_log exposes the raw network log.

• Energy and Insights analysis. Live power by zone and device, day/week/month/year energy reports, and timestamped historical sensor and meter data, so the model can answer "what is using power right now" or "how has the bedroom temperature trended this week".

• App memory and usage analysis. analyze_app_usage cross-references every app against RAM, device counts and flow references to flag safe removal candidates and estimate savings. Read-only and advisory.

• Build automations from scratch. A flow-card discovery engine (list_flow_cards, get_flow_card) returns each card's full argument schema, and full standard and Advanced Flow CRUD (including delete) lets an AI author and tear down the whole cards graph by UUID.

• Infrastructure operations from one interface. Backups, reboot, update checks, memory and storage usage, drivers, LED ring, session and location info.

• A future-proof escape hatch. homey_api_call reaches any Homey Web API endpoint directly, so new firmware features work without waiting for a tool update.

It runs on a hardened, non-root node:22-alpine image whose every build and release is gated on a Trivy scan, and it is published to Docker Hub, GHCR and the public MCP Registry. See the tool reference below for the full list.

When the official server is the better fit

This server is local-first and self-hosted, which is both its strength and its trade-off. The official Homey MCP is the easier choice when you want:

• Zero setup and managed hosting. Add one URL and sign in with your Homey account. There is no container to run, expose, or maintain, and there is a one-click ChatGPT app.

• Secure remote access from anywhere. Athom brokers the connection through its cloud, so it works away from home without exposing anything on your LAN. This server's HTTP mode is intended for a trusted local network; remote use is your own VPN or authenticated reverse proxy.

• Every Homey model. The official endpoint reaches Homey Cloud, Pro, Pro mini and Self-Hosted Server, including cloud-only setups that have no local API. This server targets a Homey reachable over its local API or your Athom token, so it is happiest with a Homey Pro.

• First-party support. It is maintained by Athom, kept in step with firmware, and officially tested with Claude and the ChatGPT app. This project is independent and best-effort.

The two are complementary. Many people use the official connector for quick remote control and this server for the deep local diagnostics, energy analysis, and infrastructure work. Athom does not publish a formal tool list, so the official server may also include capabilities not reflected above.

Quick Start

git clone https://github.com/Ringosystems/Homey-Wan-Kenobi-MCP.git
cd Homey-Wan-Kenobi-MCP
npm install
npm run build

Authenticate with your Homey:

npx homey login
npx homey select

Add to your MCP client config (Kiro, Claude Desktop, Cline, etc.):

{
  "mcpServers": {
    "homey": {
      "command": "node",
      "args": ["/path/to/Homey-Wan-Kenobi-MCP/dist/index.js"]
    }
  }
}

Authentication

The server supports two authentication methods:

Homey CLI (recommended) runs npx homey login and npx homey select. The server reads the stored OAuth token from ~/.athom-cli/settings.json automatically.

Local API Key is created at my.homey.app. Set environment variables:

export HOMEY_ADDRESS=http://192.168.1.x
export HOMEY_TOKEN=your-api-key

The local API key method is the recommended choice when running self-hosted in a container, since it does not depend on a mounted CLI settings file.

Self-Hosted (Docker / HTTP)

The image is published at ringosystems/homey-wan-kenobi (mirrored to ghcr.io/ringosystems/homey-wan-kenobi), and the server is listed in the MCP Registry as io.github.Ringosystems/homey-wan-kenobi-mcp. It is built on node:22-alpine, runs as a non-root user, and ships no baked-in secrets. See SECURITY.md for the audit details.

It defaults to the stdio transport so an MCP client can launch it directly, and exposes a long-lived streamable-HTTP service (via supergateway at /mcp, health at /healthz) when you set MCP_TRANSPORT=streamable-http.

Run as an MCP client (stdio)

docker run -i --rm \
  -e HOMEY_ADDRESS=http://192.168.1.x \
  -e HOMEY_TOKEN=your-local-api-key \
  ringosystems/homey-wan-kenobi:latest

Run as an HTTP service

docker run -d -p 8000:8000 \
  -e MCP_TRANSPORT=streamable-http \
  -e HOMEY_ADDRESS=http://192.168.1.x \
  -e HOMEY_TOKEN=your-local-api-key \
  --restart unless-stopped \
  ringosystems/homey-wan-kenobi:latest

Docker Compose

Supply your Homey credentials via a .env file next to docker-compose.yml:

cat > .env <<'EOF'
HOMEY_ADDRESS=http://192.168.1.x
HOMEY_TOKEN=your-local-api-key
EOF

# Pull the published image, or add --build to build locally instead
docker compose up -d

The provided docker-compose.yml references the published image (with build: . as a local-build fallback) and applies container hardening (read-only root filesystem, dropped Linux capabilities, no-new-privileges, and memory/PID limits):

services:
  homey-wan-kenobi:
    image: ringosystems/homey-wan-kenobi:latest
    build: .
    container_name: homey-wan-kenobi
    ports:

    environment:
      MCP_TRANSPORT: streamable-http
      HOMEY_ADDRESS: "${HOMEY_ADDRESS:-http://192.168.1.x}"
      HOMEY_TOKEN: "${HOMEY_TOKEN:-}"
    restart: unless-stopped
    read_only: true
    tmpfs:

    cap_drop:

    mem_limit: 256m
    pids_limit: 128
    healthcheck:
      test: ["CMD", "node", "-e", "fetch('http://localhost:8000/healthz').then(r=>process.exit(r.ok?0:1)).catch(()=>process.exit(1))"]
      interval: 30s
      timeout: 5s
      retries: 3
      start_period: 20s

Build locally

docker build -t ringosystems/homey-wan-kenobi .
docker run -d -p 8000:8000 \
  -e MCP_TRANSPORT=streamable-http \
  -e HOMEY_ADDRESS=http://192.168.1.x \
  -e HOMEY_TOKEN=your-local-api-key \
  --restart unless-stopped \
  ringosystems/homey-wan-kenobi

Connecting a client

Point an MCP client at the streamable-HTTP endpoint:

{
  "mcpServers": {
    "homey": {
      "type": "streamable-http",
      "url": "http://your-host:8000/mcp"
    }
  }
}

Check health with curl http://your-host:8000/healthz.
