Core Kubernetes Resources

Core Kubernetes resource management for pods, namespaces, configmaps, secrets, and nodes. Use when listing, inspecting, or managing fundamental K8s objects.

Manage fundamental Kubernetes objects using kubectl-mcp-server's core tools.

Requires the diagnostics, ops toolsets: start kubectl-mcp-server with --toolsets default,diagnostics,ops (or MCP_TOOLSETS=default,diagnostics,ops).

When to Apply

Use this skill when:

• User mentions: "pods", "namespaces", "configmaps", "secrets", "nodes", "events"
• Operations: listing resources, describing objects, creating/deleting resources
• Keywords: "show me", "list", "get", "describe", "create", "delete"

Priority Rules

Priority	Rule	Impact	Tools
1	Check namespace exists before operations	CRITICAL	kubectl_get
2	Never expose secrets in plain text	CRITICAL	Handle kubectl_get output carefully
3	Use labels for filtering	HIGH	label_selector parameter
4	Check events after changes	MEDIUM	kubectl_get

Quick Reference

Task	Tool	Example
List pods	kubectl_get	kubectl_get(resource_type="pods", namespace="default")
Describe pod	kubectl_describe	kubectl_describe(name, namespace)
Get logs	kubectl_logs	kubectl_logs(name, namespace)
List namespaces	kubectl_get	kubectl_get(resource_type="namespaces")
Get configmap	kubectl_get	kubectl_get(resource_type="configmaps", name, namespace)
List nodes	kubectl_get	kubectl_get(resource_type="nodes")

Pods

python

kubectl_get(resource_type="pods", namespace="default")
kubectl_get(resource_type="pods", namespace="kube-system", label_selector="app=nginx")

kubectl_describe(resource_type="pod", name="my-pod", namespace="default")

kubectl_logs(pod_name="my-pod", namespace="default")
kubectl_logs(pod_name="my-pod", namespace="default", previous=True)

delete_resource(resource_type="pod", name="my-pod", namespace="default")

Namespaces

python

kubectl_get(resource_type="namespaces")

kubectl_create(resource_type="namespace", name="my-namespace")

delete_resource(resource_type="namespace", name="my-namespace")

ConfigMaps

python

kubectl_get(resource_type="configmaps", namespace="default")

kubectl_get(resource_type="configmaps", name="my-config", namespace="default")

kubectl_apply(manifest="""
apiVersion: v1
kind: ConfigMap
metadata:
  name: app-config
  namespace: default
data:
  key: value
  config.yaml: "setting: true"
""")

Secrets

python

kubectl_get(resource_type="secrets", namespace="default")

kubectl_get(resource_type="secrets", name="my-secret", namespace="default")

kubectl_apply(manifest="""
apiVersion: v1
kind: Secret
metadata:
  name: db-credentials
  namespace: default
stringData:
  username: <username>
  password: <password>
""")

Nodes

python

kubectl_get(resource_type="nodes")

kubectl_describe(resource_type="node", name="node-1")

get_nodes_summary()

node_management(action="cordon", node_name="node-1")
node_management(action="uncordon", node_name="node-1")

node_management(action="drain", node_name="node-1")

Events

python

kubectl_get(resource_type="events", namespace="default")

kubectl_get(resource_type="events", namespace="default", field_selector="involvedObject.name=my-pod")

Multi-Cluster Support

All tools support context parameter:

python

kubectl_get(resource_type="pods", namespace="default", context="production-cluster")
kubectl_get(resource_type="nodes", context="staging-cluster")
