Nixos

Nixos MCP is a real-time Model Context Protocol (MCP) server that provides up-to-date, accurate metadata and version history for NixOS packages, options, flakes, and related configuration systems. Designed for developers, AI assistants, and devops professionals, it enables fast, reliable queries for package information, configuration options, binary cache status, and documentation—eliminating guesswork and outdated context for Nix-based environments. It exposes programmatic access to a unified index of the NixOS ecosystem, with plain text responses suitable for large language models and other MCP-compatible clients.
