This project looks to do that - GitHub - kingpanther13/Hubitat-local-MCP-server · GitHub. Have not tried it personally.
I 100% want this too. Would love to know what you ended up doing. I haven't tried this one nor the official one yet
I'm using the kingpanther MCP as posted above, seems to be quite solid so far, thinking of adding the official one too, didn't see that this existed until now tbh!
I've been using the kingpanther13 one, too. The community thread: [Release] Hubitat Local MCP server, create and edit RM rules native apps, devices, dashboards,, and generally control all aspects of your Hubitat using AI, server runs completely on your Hubitat
It's quite amazing.
