Manage pods, deployments, services, config, storage, nodes, jobs and autoscaling via the Kubernetes API.

Tools (43):

Tool	Description
`kubernetesListNamespaces`	List Kubernetes namespaces. Use to discover where workloads are deployed before other calls.
`kubernetesGetNamespace`	Get details of a namespace including labels, annotations and phase.
`kubernetesCreateNamespace`	Create a new namespace, optionally with labels. Use to isolate a new application or environment.
`kubernetesDeleteNamespace`	Delete a namespace and everything in it. Irreversible — confirm with the user first.
`kubernetesListPods`	List pods in a namespace or across all namespaces. Returns phase, IP, node, restart counts and images. Use to check workload health.
`kubernetesGetPod`	Get full details of a pod including spec, container statuses, events-ready conditions and IPs.
`kubernetesGetPodLogs`	Fetch container logs for a pod. Use to debug crashes, CrashLoopBackOff and application errors.
`kubernetesDeletePod`	Delete a pod to force a restart (the controller recreates it). Use to recover stuck pods or pick up new config.
`kubernetesListDeployments`	List deployments in a namespace or across all namespaces. Returns desired vs available replica counts for rollout health.
`kubernetesGetDeployment`	Get full details of a deployment including strategy, selector, pod template and rollout status.
`kubernetesCreateDeployment`	Create a deployment from a container image with replicas, port and env vars. Use to deploy a new stateless workload.
`kubernetesScaleDeployment`	Scale a deployment to a replica count. Use to handle traffic spikes or scale down idle workloads.
`kubernetesRestartDeployment`	Rolling-restart a deployment (kubectl rollout restart equivalent). Use to pick up new images with the same tag or fresh config.
`kubernetesDeleteDeployment`	Delete a deployment and its pods. Services, config and PVCs are left untouched — confirm with the user first.
`kubernetesListStatefulSets`	List StatefulSets for stateful workloads like databases and queues. Returns desired vs ready replicas.
`kubernetesListDaemonSets`	List DaemonSets running node-level agents like log collectors and CNI plugins. Returns scheduling status.
`kubernetesListReplicaSets`	List ReplicaSets backing deployments. Use to inspect rollout history and old revisions during a stuck rollout.
`kubernetesListServices`	List services in a namespace or across all namespaces. Returns type, cluster IP and ports for service discovery.
`kubernetesGetService`	Get full details of a service including selector, ports, endpoints-ready status and load balancer ingress.
`kubernetesCreateService`	Create a ClusterIP, NodePort or LoadBalancer service for a set of pods. Use to expose a deployment inside or outside the cluster.
`kubernetesDeleteService`	Delete a service. Pods keep running but lose the stable endpoint — confirm with the user first.
`kubernetesListIngresses`	List ingresses with hosts, paths and backend services. Use to audit external HTTP routing into the cluster.
`kubernetesGetIngress`	Get full ingress details including TLS config, rules, paths and load balancer status.
`kubernetesListConfigMaps`	List ConfigMaps. Returns names and data keys only (never values) for config auditing.
`kubernetesGetConfigMap`	Get a ConfigMap including its data. Use to inspect application configuration mounted into pods.
`kubernetesCreateConfigMap`	Create a ConfigMap from key/value pairs. Use to add non-sensitive configuration for pods to consume.
`kubernetesListSecrets`	List secrets returning metadata and data keys only — values are never exposed. Use to audit secret presence and types.
`kubernetesListPersistentVolumeClaims`	List PersistentVolumeClaims with bound volumes, storage class, capacity and phase. Use to debug Pending pods waiting on storage.
`kubernetesGetPersistentVolumeClaim`	Get a PersistentVolumeClaim including access modes, resources, selectors and bound volume details.
`kubernetesListPersistentVolumes`	List cluster PersistentVolumes with capacity, reclaim policy, storage class and claim binding. Use for storage capacity planning.
`kubernetesListNodes`	List cluster nodes with Ready status, capacity, allocatable resources and versions. Use for capacity and upgrade planning.
`kubernetesGetNode`	Get full node details including addresses, taints, images, volumes and system info.
`kubernetesCordonNode`	Mark a node unschedulable (kubectl cordon equivalent). Use before draining or maintaining a node.
`kubernetesUncordonNode`	Mark a node schedulable again (kubectl uncordon equivalent). Use after maintenance completes.
`kubernetesListJobs`	List batch jobs with active/succeeded/failed counts. Use to check one-off task and migration outcomes.
`kubernetesListCronJobs`	List CronJobs with schedules, suspend state and last schedule time. Use to audit recurring workloads.
`kubernetesCreateJob`	Create a one-off batch job from a container image and command. Use for migrations, scripts and manual triggers of cron work.
`kubernetesDeleteJob`	Delete a batch job and its pods. Use to clean up finished or stuck jobs.
`kubernetesListHorizontalPodAutoscalers`	List HorizontalPodAutoscalers with current vs desired replicas, targets and scaling status.
`kubernetesGetHorizontalPodAutoscaler`	Get an HPA including scale target, metrics (CPU/memory/custom) and recent scaling conditions.
`kubernetesGetClusterVersion`	Get the Kubernetes server version, git commit and platform. Use to check upgrade status and API compatibility.
`kubernetesListApiGroups`	Discover available API groups and versions (apps/v1, batch/v1, networking.k8s.io/v1...). Use to check feature support before other calls.
`kubernetesListEvents`	List cluster events (warnings, scheduling failures, image pulls). Use first when debugging unhealthy resources.
