MetaDock vs MCP Nixos

A side-by-side look at the MetaDock and MCP Nixos MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

MCP Nixos tools 2

  • nixQuery 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.

Frequently asked questions

MetaDock is categorized under OS Automation and uses a remote HTTP/SSE transport. MCP Nixos belongs to OS Automation and uses a local stdio subprocess. Pick MetaDock for os automation work and MCP Nixos for os automation.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

MetaDock has no declared pricing — check the project's own site. MCP Nixos is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add metadock and utensils-mcp-nixos as separate keys in the same mcpServers object, and your assistant will call tools from either one.
