Letting Claude take control of Home Assistant sounded amazing—but it was far from perfect

Welcome! In this article, we will break everything down in a simple and practical way.

Introduction

It’s possible to connect Home Assistant to AI services such as Claude. Depending on the connector you use, your AI chatbot can not only read information about your smart home but also write automations, build dashboards, turn things on and off, and more. I’d seen plenty of people rave about it, so I decided to see what all the fuss was about.
Home Assistant has its own Model Context Protocol server

Home Assistant has its own native Model Context Protocol server (MCP) that you can use to connect an AI chatbot to your smart home. However, Home Assistant’s MCP server is quite limited in scope; it exposes Home Assistant through the Assist API, allowing AI clients to access information about exposed entities and control them, but it doesn’t provide direct access to Home Assistant’s configuration, automations, dashboards, or entity registry. However, there are also some community MCP servers that let you do a lot more. I installed the Unofficial and Awesome Home Assistant MCP Server, which is a terrible name, so I will henceforth call it HA-MCP, as that’s what it’s called in the GitHub URL. HA-MCP allows you to both read and modify many parts of Home Assistant, making it both more powerful and potentially riskier to use.

Granting an AI chatbot access to your Home Assistant server is not risk-free. You may expose sensitive information, or the AI may mistakenly take actions that can damage your setup and potentially cause data loss. You should use it at your own risk.

Home Assistant Green is a pre-built hub directly from the Home Assistant team. It’s a plug-and-play solution that comes with everything you need to set up Home Assistant in your home without needing to install the software yourself.

The first things I got Claude to do

Issues were quickly identified

I’d put off trying HA-MCP because giving a third-party AI chatbot access to my Home Assistant server didn’t sit well. Privacy is a core focus of Home Assistant and exposing a huge amount of information about my smart home to an AI company is far from private. However, since I was planning to rebuild Home Assistant from scratch, I figured I would give it a try as it didn’t really matter if Claude decided to delete everything. Setting up the MCP server is fairly simple to do, and the first thing I did was ask Claude to take a look at my system and see if it could identify any issues. It quickly scanned through more than 1,700 entities and 118 integrations and identified some significant problems, including the fact that my automatic backups hadn’t been running for a couple of weeks because I was close to the storage limit of my Home Assistant VM in Proxmox. This was something I’d completely missed and could easily have led to me losing anything that I’d created in the past couple of weeks, so I was already impressed. After fixing this and a few other issues Claude had found, I got Claude to find any unused entities, integrations, and automations that I no longer needed, and it was able to remove them all once granted permission.

Claude was clearly useful for these types of admin tasks, but what I really wanted to try out was using Claude to create something new. It was time to let AI build an automation.

I let Claude control my computer—and it filled my Amazon basket

AI does the boring stuff, just not very fast.

Where using Claude really shines

You can create automations with natural language

Using Claude to create automations is honestly a dream. You just tell Claude what you want the automation to do, and it finds the relevant entities and builds the entire automation for you. If you’re trying to create something complex, it’s so much easier than trying to do it yourself. All of the automations that Claude built for me worked as expected, and I couldn’t see any obvious issues in the YAML. I also tried building a dashboard. I wanted to create a weather dashboard that used the same classic weather icons that I remember from weather reports growing up. I told Claude what I wanted and uploaded an image of an old weather report, and Claude got to work. It took a few iterations to get things how I wanted them, but in just a few minutes I had a dashboard that looked far better than I could have built myself. Using Claude really does make creating things in Home Assistant far more accessible.
It wasn’t all smooth sailing

AI can and will get things wrong

That’s not to say that using the HA-MCP was perfect. I hit several frustrations and ended up having to fix some parts myself. I wanted to create a dashboard to display all the fixtures and live scores for the 2026 soccer World Cup. Claude created a new dashboard and installed the TeamTracker integration and dashboard card. It also gave me the YAML to paste into my configuration file to create the sensors for each team in the World Cup. This is where things started to go wrong. Claude started to include countries that aren’t even in the 2026 World Cup, and many of the country abbreviations it used were wrong, so the cards wouldn’t load. When I pointed this out, Claude tried to fix things but ended up making it worse, changing the sensors so that some of the sensors that had been working were also now broken. After a lot of back and forth that ate up much of my Claude usage, I gave up and fixed the problems myself.
What HA-MCP can’t do

While HA-MCP is powerful, there were still some things it couldn’t do in my setup. One thing that surprised me was that despite the ability to rename entities, create dashboards, or build automations, without using additional custom components, Claude is unable to make any changes to the configuration.yaml. It is possible to use an add-on to grant access to the configuration, but I didn’t have this installed.

When I was creating the sensors for my World Cup dashboard, for example, I had to add them to the configuration file manually, which soon became tiresome as Claude kept getting the code wrong, so there was a lot of copying and pasting. This was exactly what I was aiming to avoid by using HA-MCP. In the end, I gave up on my experiment and rebuilt Home Assistant from scratch. While being able to build automations and dashboards using Claude is useful, you can always just ask Claude to create the YAML for automations or dashboards and paste it into Home Assistant yourself, which is what I ended up having to do some of the time anyway. While it’s a bit more effort, you don’t need to expose your smart home to an AI company or risk having it delete everything you’ve ever built.

AI can be useful but it’s not a silver bullet

My time using the HA-MCP was interesting, but I’m not going to use it going forward. While it makes some things a lot easier, there are plenty of downsides, too. It’s tempting to rely on AI to do everything for you, but I’d rather maintain some control, and keep my smart home as private and local as possible.
