Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@cachyos-mcp check for available system updates"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
All-in-one Arch/CachyOS deep system control MCP server. It provides
pacman + AUR package intelligence and system updates, and bundles the complete
network-mcp and sysprobe-mcp tool sets
so a single server gives Claude full visibility and control of the machine.
The two generic servers stay independently deployable (e.g. ship network-mcp
to a headless server); cachyos-mcp just embeds their register() entry points.
Package intelligence (read-only)
search_all_repositories — repos and AUR in one call, unified & sorted
(the anti-hallucination tool: see every available variant + votes + installed)
search_system_repos, search_aur
get_package_info, get_aur_info, get_package_dependencies
query_installed_packages, which_package_owns, list_package_files
list_orphans, list_explicit_packages
check_updates (repos via checkupdates + AUR via paru — no root, safe)
get_pacman_log, get_mirrorlist, list_kernels, get_package_cache_info
Mutating (needs SYSCONTROL_ALLOW_ACTIONS=1)
system_update, install_packages, install_aur_package,
clean_package_cache
remove_packages — never auto-executed; returns the command only
pacman needs root. Gated write tools run via passwordless sudo if available,
otherwise they return the exact command for you to run (in Claude Code, prefix
with !). To let Claude apply updates directly, add a sudoers rule, e.g.:
tom ALL=(root) NOPASSWD: /usr/bin/pacman, /usr/bin/paccacheRelated MCP server: homebutler

sysprobe: sensors, processes, systemd/journal, coredumps, dmesg, D-Bus, hardware inventory, brightness, power profile, CPU governor, audio, media, app launch, bluetooth, KDE control, session/power …

-- uv --directory "/home/tom/Projekte/SE Projects/cachyos-mcp" run cachyos-mcpIf you register cachyos-mcp you get everything; you typically would not also register network-mcp / sysprobe-mcp locally (only when deploying them elsewhere).
pacman (always), and optionally pacman-contrib (checkupdates/paccache),
paru (AUR), pactree/expac. Network/sysprobe optional tools as listed in
their READMEs.
