| 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. | Postman is the world's leading API platform used by over 30 million developers and 500,000 organizations. From API design to testing, mocking, and documentation, Postman provides everything you need to build better APIs faster. |
