MCP-5 of milestone 461 "MCP server: Steward as an LLM-inspectable, LLM-operable hub". Contributed through each plugin's register_mcp_tools hook, so they exist only while the plugin is enabled. docker (viewer, read-only): - list_containers: filter by host, status, compose project, or problem (restarting, crash_looping, unhealthy, oom_killed, exited_nonzero); problems sort first and each row names what is wrong. - get_container: state, CPU/memory history across the raw/hourly seam, lifecycle events. A unique part of a swarm task name is enough. - list_swarm_services: replicas per node (agent-less placements as ghosts) and the swarm's nodes. - search_container_logs: text (% and _ literal), stream, range, context lines, paging by a full-precision `before` cursor; over-long lines keep both ends and say how much of the middle was cut. - get_docker_disk_usage: bytes per host, reclaimable first. - mcp_overview: failing containers and under-replicated swarm services join get_overview. host_agent: list_agents (reporting / stale / pending, version, OS), and an overview finding for agents registered over 30 minutes ago that never checked in. Settings > Thresholds gains the TLS-expiry warn/crit days (were 14/3 in code) and the crash-loop deaths-per-hour count (3), which get_overview and the docker tools now read.
