Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "denon": {
      "command": "uvx",
      "args": [

        "DENON_HOST": "your-value",
        "DENON_PORT": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add denon --env DENON_HOST=your-value --env DENON_PORT=your-value -- uvx denon-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

DENON_HOST required env
IP address of the Denon receiver
DENON_PORT env
Telnet port of the receiver

Common questions

Is Denon AVR safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DENON_HOST

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.2) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

Denon MCP Server

English summary. MCP server for Denon AVR home-cinema receivers over the local telnet control protocol: power, volume, mute, inputs, status. Configure with DENON_HOST / DENON_PORT (optional DENON_MAC to follow the receiver when DHCP changes its IP) or a config.yaml; runs standalone (uvx denon-mcp after PyPI publication).

Serveur MCP pour contrôler un Home Cinema Denon AVR via le protocole Denon AVR Control (telnet).

Démo

Enregistrée sur l'ampli réel avec docs/demo/record.sh : un client MCP minimal (docs/demo/mcp_demo.py) démarre le serveur en stdio avec DENON_HOST dans l'environnement, liste les outils et appelle get_status (lecture seule).

Modèle supporté

Denon AVR-X1700H DAB
Autres modèles AVR-X series compatibles avec le protocole Denon AVR Control

Configuration

Ordre de résolution : variables d'environnement, puis fichier YAML (DENON_CONFIG, sinon ./config.yaml, sinon config.yaml à côté du serveur, sinon celui de Lyra si le serveur est installé dans son arborescence). Le serveur fonctionne seul, sans Lyra.

Sans réservation DHCP, renseignez aussi mac (ou DENON_MAC) : si l'IP ne répond plus, le serveur retrouve le Denon par son adresse MAC dans la table de voisinage du réseau local (une recherche toutes les 2 min au plus) et bascule sur la nouvelle IP.

Installation en une ligne

uvx denon-mcp          # après publication sur PyPI ; en attendant : uvx --from git+https://github.com/amineutron/denon-mcp denon-mcp

Configuration Claude Desktop / Claude Code (mcpServers) :

{ "denon": { "command": "uvx", "args": ["denon-mcp"], "env": { "DENON_HOST": "192.0.2.22" } } }

Ajouter dans config.yaml :

denon:

host: "192.0.2.10" # IP du Denon (exemple) port: 23 # Port telnet (default: 23)

Les valeurs ci-dessous sont des exemples : remplacez-les par les valeurs de votre appareil (IP affichée dans le menu réseau de l'ampli, adresse MAC au format AA:BB:CC:DD:EE:FF utile pour une réservation DHCP ou le Wake-on-LAN).

Outils disponibles

Outil	Rôle
`volume_set`	Regle le volume du Denon a un niveau specifique (0-98). 80 = 0dB reference.
`volume_up`	Augmente le volume du Denon.
`volume_down`	Baisse le volume du Denon.
`mute_on`	Active le mute du Denon.
`mute_off`	Desactive le mute du Denon.
`mute_toggle`	Toggle le mute du Denon (on/off).
`power_on`	Allume le Denon AVR.
`power_off`	Eteint le Denon AVR (standby).
`get_status`	Retourne le statut du Denon : volume, power (on/standby/unknown), muted, source (BD, TV, GAME...), reachable.
`set_input`	Change la source d'entree du Denon (BD, TV, GAME, SAT/CBL, DVD, MPLAY).

Sources d'entrée

BD : Blu-ray / Lecteur BD
TV : Entrée TV
GAME : Console de jeu
SAT/CBL : Satellite / Câble
DVD : Lecteur DVD
MPLAY : Media Player

Aliases supportés : bluray, blu-ray, cable, sat, media, mediaplayer

Échelle de volume

0-98 : Échelle Denon (0 = -80 dB, 80 = 0 dB référence, 98 = +18 dB)
Pour une écoute normale : 30-50
Pour un home cinéma : 50-70
Maximum recommandé : 80 (0 dB)

Protocole Denon AVR Control

Commandes telnet sur port 23 :

MV44 : Volume 44
MV? : Demander le volume actuel
MVUP / MVDOWN : Volume +/-
PWON / PWSTANDBY : Power on/off
MUON / MUOFF : Mute on/off
SIBD : Source Blu-ray

Notes HDMI ARC

Quand un home cinéma est connecté en HDMI ARC/eARC à la TV :

Le volume de la TV est désactivé
C'est le home cinéma qui contrôle le volume audio
Les commandes tv.volume_* ne fonctionnent PAS
Utiliser denon.volume_* à la place

Test manuel

# Test connexion

echo "MV?" | nc 192.0.2.10 23

Régler volume à 44

echo "MV44" | nc 192.0.2.10 23

Allumer

echo "PWON" | nc 192.0.2.10 23

Installation

denon-mcp                     # installé (pip, uvx) ; `denon-mcp --help` liste les réglages

python -m denon_mcp # équivalent, depuis tout environnement où le paquet est installé python server.py # depuis un clone, sans installation (lanceur minimal, code dans denon_mcp/)

Le code vit dans le paquet denon_mcp : il s'installe à côté d'autres serveurs MCP sans conflit de nom de module. Le serveur est automatiquement lancé par Lyra via la config MCP.
