Look up any NixOS package, module option, or Home Manager setting from chat — 130k packages + 23k options, no setup.
mcp-nixos queries NixOS packages, system options, Home Manager, nix-darwin, Nixvim, and related registries through two tools. No auth, no local Nix install required — it proxies to public search APIs. Ideal for answering 'is there a package for X?' and 'what's the option for Y?' without hunting through docs.
