How to setup claude-code and mcp-nixos on NixOS
Edited 9/21/25 (Removed previous setup guide). Nothing ever stays the same it seems, especially surrounding using LLM's and NixOS lately. As of now, I recommend using the claude-code package on stable and the mcp-nixos package on unstable . So much easier than what I was
