mcp-nixos

Active·★ 864·MIT·Updated 2026-09-05

MCP-NixOS is an MCP server that provides real-time, accurate information about NixOS packages, options, Home Manager, nix-darwin, and more. It works on any system without requiring Nix, using just two tools to query multiple sources.

mcp-nixos sits in the Dev Tooling category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Unified query tool with multiple actions and sources. A representative use case is AI assistant queries NixOS package information. The listed license is MIT. GitHub stars are currently 864. Relevant tags include ai-assistant, ai-integration.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
