概要

What is MCP-NixOS?

MCP-NixOS is an MCP server that provides accurate, real-time information about NixOS packages, options, Home Manager, nix-darwin, Nixvim, FlakeHub, Noogle, NixOS Wiki, nix.dev, package versions (via NixHub), binary cache status, and local flake inputs. It integrates with multiple APIs and is designed for AI assistants that need reliable NixOS data without hallucinations. It works on any system (Windows, macOS, Linux) and does not require Nix installed.

How to use MCP-NixOS?

Install and run via uvx mcp-nixos (recommended), pip install mcp-nixos, nix run github:utensils/mcp-nixos, or Docker (ghcr.io/utensils/mcp-nixos). Configure as an MCP server in your client (e.g., Cursor, Claude, Pi) using the nixos server name. Two tools are provided: nix (unified query with actions like search, info, stats, cache, flake-inputs) and nix_versions (package version history). Transport defaults to STDIO; set environment variables MCP_NIXOS_TRANSPORT=http and optionally MCP_NIXOS_HOST, MCP_NIXOS_PORT, MCP_NIXOS_PATH, MCP_NIXOS_STATELESS_HTTP for HTTP mode.
