Q: Which integrations are available for this server?

Allows control of Zigbee lights, sensors, groups, scenes, rules, and schedules through a deCONZ gateway.

deConz MCP Server

An MCP (Model Context Protocol) server that exposes the deCONZ REST API to AI assistants. Control Zigbee lights, sensors, groups, scenes, rules, and schedules through natural language.

Supports stdio, SSE, and Streamable HTTP transports. HTTP transports are protected by a configurable bearer token.

Requirements

Python ≥ 3.10
uv (recommended) or pip
A running deCONZ / Phoscon gateway with a ConBee or RaspBee adapter
A valid deCONZ REST API key (see Obtaining an API key)

Related MCP server: zont-mcp

Installation

# Clone the repository
git clone https://github.com/your-org/deconz-mcp.git
cd deconz-mcp

# Install with uv (creates an isolated virtual environment)
uv sync

# Or install with pip into your environment
pip install -e .

Obtaining an API key

Open the Phoscon App in your browser (usually http://<gateway-ip>/pwa).
Go to Menu → Settings → Gateway → Advanced.
Click Authenticate app — this opens the network for 60 seconds.
Within those 60 seconds, run:

curl -s -X POST http://<gateway-ip>/api \
  -H "Content-Type: application/json" \
  -d '{"devicetype": "deconz-mcp"}'

The response contains your API key:

[{"success": {"username": "YOUR-API-KEY-HERE"}}]

Store it as DECONZ_API_KEY.

Quick start

stdio (Claude Desktop)

DECONZ_HOST=192.168.1.10 DECONZ_API_KEY=abc123def deconz-mcp

Streamable HTTP with bearer auth

DECONZ_HOST=192.168.1.10 \
DECONZ_API_KEY=abc123def \
MCP_AUTH_TOKEN=my-mcp-secret \
deconz-mcp --transport streamable-http --host 0.0.0.0 --port 8080

Combined SSE + Streamable HTTP

DECONZ_HOST=192.168.1.10 \
DECONZ_API_KEY=abc123def \
MCP_AUTH_TOKEN=my-mcp-secret \
deconz-mcp --transport server --host 0.0.0.0 --port 8080

* Not required when using stdio and calling configure_deconz at runtime.
† Strongly recommended for HTTP transports exposed beyond localhost.

CLI reference

usage: deconz-mcp [--transport {stdio,sse,streamable-http,server}]
                  [--host HOST] [--port PORT]
                  [--log-level {DEBUG,INFO,WARNING,ERROR}]
                  [--auth-token TOKEN] [--base-url URL]

Transport modes

Mode	Endpoint(s)	Description
`stdio`	stdin/stdout	Pipe-based — for Claude Desktop and local use
`sse`	`/sse`, `/messages/`	Legacy SSE (MCP pre-2025-03-26)
`streamable-http`	`/mcp`	Modern Streamable HTTP (MCP 2025-03-26)
`server`	all of the above	SSE + Streamable HTTP on one port

Authentication

deCONZ API key

The deCONZ REST API key is a gateway credential that travels as part of the URL path (/api/<apikey>/...). It is configured server-side via DECONZ_API_KEY and is never exposed to MCP clients.

MCP bearer token

The MCP_AUTH_TOKEN / --auth-token option protects the MCP server itself. Every HTTP request from an MCP client must include:

Authorization: Bearer <token>

The token is verified with a constant-time comparison to prevent timing attacks. When running over localhost only (default bind 127.0.0.1), bearer auth is optional but recommended.

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "deconz": {
      "command": "deconz-mcp",
      "env": {
        "DECONZ_HOST": "192.168.1.10",
        "DECONZ_API_KEY": "your-api-key-here"
      }
    }
  }
}

Or if installed in a virtual environment:

{
  "mcpServers": {
    "deconz": {
      "command": "/path/to/deconz-mcp/.venv/bin/deconz-mcp",
      "env": {
        "DECONZ_HOST": "192.168.1.10",
        "DECONZ_API_KEY": "your-api-key-here"
      }
    }
  }
}

HTTP client configuration

For Streamable HTTP transport:

{
  "mcpServers": {
    "deconz": {
      "url": "http://localhost:8080/mcp",
      "headers": {
        "Authorization": "Bearer my-mcp-secret"
      }
    }
  }
}

For legacy SSE transport:

{
  "mcpServers": {
    "deconz": {

      "headers": {
        "Authorization": "Bearer my-mcp-secret"
      }
    }
  }
}

Docker

A pre-built multi-platform image (linux/amd64 + linux/arm64) is published to the registry:

registry.mne.pl/deconz-mcp:latest
registry.mne.pl/deconz-mcp:0.1.0

A multi-stage Dockerfile is also included if you prefer to build locally. The builder stage uses the official uv image to install dependencies and compile the package as a wheel; the runtime stage is python:3.12-slim (57 MB total).

Pull

docker pull registry.mne.pl/deconz-mcp:latest

Build locally

# Single-platform (current machine)
docker build -t deconz-mcp:latest .

# Multi-platform push (requires a buildx builder with multi-platform support)
docker buildx build \
  --platform linux/amd64,linux/arm64 \
  --tag registry.mne.pl/deconz-mcp:latest \
  --tag registry.mne.pl/deconz-mcp:0.1.0 \
  --push .

Run — HTTP server (SSE + Streamable HTTP)

docker run -p 8000:8000 \
  -e DECONZ_HOST=192.168.1.10 \
  -e DECONZ_API_KEY=abc123def \
  -e MCP_AUTH_TOKEN=my-mcp-secret \
  registry.mne.pl/deconz-mcp:latest

Run — stdio

docker run -i \
  -e DECONZ_HOST=192.168.1.10 \
  -e DECONZ_API_KEY=abc123def \
  registry.mne.pl/deconz-mcp:latest --transport stdio

Docker Compose

A ready-to-use Compose file is in docs/docker-compose.yml. It defines two services:

Service	Transport	Started by default
`deconz-mcp`	`server` (SSE + Streamable HTTP) on port 8000	Yes
`deconz-mcp-stdio`	`stdio`	No — requires `--profile stdio`

# Copy and edit the environment file
cp .env.example .env   # set DECONZ_HOST, DECONZ_API_KEY, MCP_AUTH_TOKEN

# Start the HTTP server
docker compose -f docs/docker-compose.yml up

# Run a one-shot stdio session
docker compose -f docs/docker-compose.yml --profile stdio run --rm deconz-mcp-stdio

Use the stdio service in Claude Desktop:

{
  "mcpServers": {
    "deconz": {
      "command": "docker",
      "args": ["compose", "-f", "/path/to/docs/docker-compose.yml",
               "--profile", "stdio", "run", "--rm", "deconz-mcp-stdio"],
      "env": {
        "DECONZ_HOST": "192.168.1.10",
        "DECONZ_API_KEY": "your-api-key-here"
      }
    }
  }
}

Kubernetes

The manifest at k8s/deployment.yaml contains all resources needed to run the server in a cluster:

Resource	Purpose
`Namespace`	`deconz-mcp` — isolates all resources
`Secret`	`DECONZ_API_KEY` and `MCP_AUTH_TOKEN` (base64-encoded)
`ConfigMap`	`DECONZ_HOST`, `DECONZ_PORT`, `DECONZ_TLS`, `MCP_BASE_URL`
`Deployment`	1 replica, non-root, read-only root FS, resource limits
`Service`	`ClusterIP` on port 80 → pod 8000
`Ingress`	Commented-out template for nginx / cert-manager

Deploy

# 1. Encode your secrets
echo -n 'your-api-key'   | base64   # → paste into Secret.DECONZ_API_KEY
echo -n 'your-mcp-token' | base64   # → paste into Secret.MCP_AUTH_TOKEN

# 2. Edit the ConfigMap (DECONZ_HOST, MCP_BASE_URL) in k8s/deployment.yaml

# 3. Apply
kubectl apply -f k8s/deployment.yaml

# 4. Verify
kubectl -n deconz-mcp get pods
kubectl -n deconz-mcp logs -f deploy/deconz-mcp

Health check

kubectl -n deconz-mcp port-forward svc/deconz-mcp 8000:80
curl http://localhost:8000/health
# {"status": "ok", "deconz_configured": true}

The Deployment configures both a liveness probe and a readiness probe against /health, so Kubernetes automatically restarts the pod if the server becomes unresponsive.

Ingress (optional)

Uncomment the Ingress section at the bottom of k8s/deployment.yaml and set your hostname. TLS termination happens at the ingress controller; the pod always speaks plain HTTP internally.

Health check

HTTP transports expose a liveness probe:

curl http://localhost:8080/health
# {"status": "ok", "deconz_configured": true}

Data & Privacy

Preliminary assessment only — not legal advice. See full notes below.

Personal home use

When this server runs in a private household and is accessed only by the residents, processing of smart-home device data is likely covered by the household exemption (GDPR Recital 18). In that scenario the GDPR does not apply and no additional compliance steps are required.

Commercial or shared deployments

Deploying this server in offices, rental properties, hotels, co-working spaces, or any environment where you process data on behalf of other people takes you outside the household exemption. In those cases:

Presence and motion sensor data constitutes personal behavioral data (Art. 4(1) GDPR). Establish a documented lawful basis (Art. 6) before processing it.
Conduct a Data Protection Impact Assessment (Art. 35) if the deployment involves systematic monitoring of occupants on a large scale.
Provide a privacy notice to data subjects describing what is collected, for how long, and under what legal basis.

Security recommendations

Risk	Recommendation
API key exposed in URL paths and server access logs	Rotate the deCONZ API key periodically; restrict access to gateway logs
Unencrypted transport	Enable TLS for any network-facing deployment (`DECONZ_TLS=true`); use a reverse proxy with a valid certificate
MCP endpoint publicly accessible	Always set `MCP_AUTH_TOKEN` when binding to a non-loopback address

What this software does NOT do

No data is sent to third parties, analytics services, or cloud providers.
No telemetry, tracking pixels, or consent libraries are present in this codebase.
All communication stays between the MCP client, this server, and the local deCONZ gateway.

Legal notice

This GDPR assessment was generated as a preliminary, exploratory evaluation. It does not constitute legal advice and does not replace a legal audit. For binding guidance, consult a qualified data protection lawyer in your jurisdiction.
