List all admin services this MCP can reach (Uptime Kuma, NPMPlus/Nginx Proxy Manager, Porkbun, Cloudflare, Docker, Proxmox), which are configured, and which named instances exist for each (e.g. multiple Docker hosts or Proxmox nodes with separate credentials). Call this first if you're unsure what's available.

Search/list available actions across configured services. Returns each action's id, owning service, a one-line summary, whether it's read-only or destructive, and its JSON input schema. Use query to search by keyword (e.g. 'restart container', 'dns record', 'proxy host'); omit both filters to list everything. Only configured services' actions are returned.

Execute one action against one instance of a service. Look up the action id and its params schema via list_actions first. instance selects which configured target to use (e.g. which Proxmox node or Docker host) - omit it only if the service has exactly one instance configured. Destructive actions (as flagged by list_actions) change or delete remote state - double check params before calling.
