Zigbee2MQTT MCP server

This is a helper that connects your AI assistant to Zigbee2MQTT, the software many people use to run Zigbee smart home devices. It is handy if you already have Zigbee lights, sensors and remotes and you want to ask questions about how the network is doing instead of clicking around the Zigbee2MQTT web page. You do not need Home Assistant for it to work.

What this MCP server does

You ask your AI something like whether your Zigbee network is healthy. The AI passes that question to this helper program. The helper talks to your MQTT broker, which is the message service Zigbee2MQTT uses, and reads the latest information Zigbee2MQTT publishes there. It then hands the answer back to the AI, which explains it to you in the chat. If you have turned on write access, it can also send small commands back, like telling a device to pair or updating a setting.

What you can do with it

• Check the overall health of your Zigbee network
• Find devices with weak signal or low battery
• See which devices have firmware updates waiting
• Open the network for pairing a new device for a set time
• Rename a device or change its settings
• Bind a remote directly to a light so it still works if the bridge is down
• Look at the mesh map to see which devices talk through which

Try asking your AI

• “Is my Zigbee network healthy?”
• “Which devices have the weakest signal?”
• “Which batteries need replacing?”
• “Any firmware updates available?”

What it gives back to you

You get answers in plain chat text: lists of devices, short health summaries, warnings about weak links or low batteries, and notes about anything that looks off. When you ask it to change something, it tells you what it did. For bigger questions it can give you a whole-estate report in one go.

Before you start

Who it's for

People who run a Zigbee smart home with Zigbee2MQTT and want an easier way to keep an eye on it, especially if they already use an AI assistant for other tasks.
