| Description | MCP-NixOS is an open-source Model Context Protocol server that gives AI coding assistants (Claude, Cursor, and any MCP-compatible client) live, accurate access to 130K+ NixOS packages, 23K+ system options, Home Manager, nix-darwin, flakes, Nix function signatures, and package version history. It's built for NixOS developers who are tired of their AI hallucinating package and attribute names, querying source APIs directly rather than relying on stale training data. Its main differentiators are an extremely small context footprint (~1,030 tokens across just two tools) and the fact that it needs no Nix installation to run, working as a plain API client on Windows, macOS, or Linux. | Vercel is the platform for frontend developers, providing the speed and reliability innovators need to create at the moment of inspiration. Built by the creators of Next.js, Vercel powers Nike, eBay, Mercedes-Benz, and millions of developers. |
