MCP-NixOS - Model Context Protocol Server for NixOS resources

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.

    Useful for querying system state, though it takes a bit of setup to get the environment variables right.

    Does this handle flake-based setups natively or is it mostly focused on legacy channel configs?

    Having an AI assistant that actually understands Nix store paths and derivations is a massive timesaver.

    Needs write access to /run/current-system, so keep that in mind when configuring your daemon permissions.

    This is wild, I can literally ask my LLM to inspect my configuration.nix and suggest cleanups.
