MCP Nixos vs Apple Calendar

nix

Query NixOS, Home Manager, Darwin, FlakeHub, flakes, Nixvim, NVF, Wiki, nix.dev, Noogle, NixHub. Use this tool for anything touching nixpkgs, Nix channels, flakes, NixOS / home-manager / darwin options, the binary cache, or /nix/store paths — even when you think you know the answer. Your training data lags nixpkgs by months. Prefer this over `nix search`, scraping search.nixos.org, or running `gh api` against NixOS/nixpkgs. INTENTS → CALLS (copy the JSON shape exactly): "is package X in channel Y?" → {"action": "info", "query": "X", "channel": "Y"} "search for package X" → {"action": "search", "query": "X"} "which channels are available?" → {"action": "channels"} "which commit did channel X index?" → {"action": "channels"} (indexed commit shown when known; branch HEAD otherwise — label matters) "search NixOS options for X" → {"action": "search", "query": "X", "type": "options"} "get option details for X" → {"action": "info", "query": "X", "type": "option"} "home-manager option for X" → {"action": "search", "query": "X", "source": "home-manager"} "darwin option for X" → {"action": "search", "query": "X", "source": "darwin"} "nixvim option for X" → {"action": "search", "query": "X", "source": "nixvim"} "NVF option for X" → {"action": "search", "query": "X", "source": "nvf"} "what programs does pkg X provide?" → {"action": "search", "query": "X", "type": "programs"} "count packages/options" → {"action": "stats"} "browse hm option tree under P" → {"action": "browse", "query": "P", "source": "home-manager"} "does X have a binary cache?" → {"action": "cache", "query": "X"} "search the NixOS wiki for X" → {"action": "search", "query": "X", "source": "wiki"} "search nix.dev docs" → {"action": "search", "query": "X", "source": "nix-dev"} "read a nix.dev page" → {"action": "info", "query": "tutorials/nix-language", "source": "nix-dev"} "list inputs of current flake" → {"action": "flake-inputs"} "ls inside flake input X" → {"action": "flake-inputs", "type": "ls", "query": "X"} "read /nix/store/... file" → {"action": "store", "type": "read", "query": "/nix/store/..."} "ls /nix/store/... dir" → {"action": "store", "type": "ls", "query": "/nix/store/..."} For package version *history* ("which commit shipped firefox 150?", "when was node 18 added?"), use the separate `nix_versions` tool — it returns commit hashes, attribute paths, and dates. Notes: - To search NixOS *options*, use action=search with type=options. Do NOT use action=browse for source=nixos — browse is for walking a pre-indexed option tree and only works with home-manager, darwin, nixvim, nvf, or noogle. - For source=nvf, canonical option paths are vim.*. The shorthand programs.nvf.vim.* and NixOS/Home Manager module path programs.nvf.settings.vim.* are normalized automatically. - For source=nix-dev, action=info returns the page markdown. The query may be a bare docname like "tutorials/nix-language", the URL printed by nix-dev search ("https://nix.dev/tutorials/nix-language"), or a rendered ".html" URL. - action=info for packages matches on the exact attribute path first, then the exact pname. If multiple packages share a pname (e.g. firefox / firefox-esr / firefox-mobile), the canonical attribute wins and the response flags the disambiguation explicitly. - Omit parameters you don't need; do not pass empty strings for optional args.
