| 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. | Razorpay is a payment gateway solution for Indian businesses that enables them to accept, process, and disburse payments via multiple methods including credit cards, debit cards, net banking, UPI, and popular wallets. It offers a developer-friendly API, robust dashboard, and a suite of products for payments, banking, lending, and payroll. |
