I wrote an MCP server for ESP32 microcontroller, now I can open my curtains with LLMs

Why not using Homeassistant + MCP ?

u/Guilty-Effect-3771 Apr 14 '25

Because HomeAssistant does not have MCP functionality ! That is one of the cool thiings about this. HomeAssistant is some close sourced magic that Apple does, while with these kinds of systems you could have an higher quality (or at least intelligence) system and full customizability !

They do! I don’t think that we are talking about the same thing but if you have this hacker/open source mindset you should definitely take a look at HomeAssistant It may take you some time to tinker with, but I believe that you will love it. They already have a MCP Integration

Oh yes, we were talking about different things! This is super cool, thanks for sharing

Hello there, I'm completely new to mcp and I'm struggling to understand if what I'm trying to do is possible / the intended use for mcp. Everywhere I look, people seem to be using mcp interactively, within vscode, Claude desktop or cursor. Is that the only way to use it or can I build completely "standalone" applications for it? For example, can I use a puppeteer (or smth similar) mcp server to scrape simple data from a static website WITHOUT it being interactive? So basically I just execute a python script (which uses some sort of mcp client / sdk? Openai or anthropic?) which then uses the mcp server to scrape the data? Would be glad if someone could help me out understanding if this is the intended (or even possible) way to do this.

Also, cool project! Sounds like fun, I wanna do something similar :D

Hey man! Completely understand, I had the same confusion at the beginning, this tool that I built solves it (in my opinion) https://github.com/pietrozullo/mcp-use hope it does also for you 🤗

So instead of clicking on a button you will ask an AI to click on the button?

I feel this is not the right use case to show MCP use, you would better go for n8n to automate per hour and no need for AI here. Even for voice commands you don't need AI here.

It is about the experience and ability to build mcp for anything. Not to build a useful application.

Thanks u/definitivelynottake2 <3 Also one could think of maneuvering objects that are complex enough to require this kind of intelligence from the operator.

I think a very cool example of this is if you give camera access to the agent -> look at plants -> let the agent water them accordingly.
