Kubernetes MCP (Cluster Operations)

Use Kubernetes MCP tools to query cluster resources for diagnostics and verification.

Tools

Tool Purpose

kubernetes_listResources

List resources of a specific type

kubernetes_getResource

Get detailed resource info

Listing Resources

List all pods in a namespace

kubernetes_listResources({ kind: "Pod", namespace: "my-service" })

List deployments

kubernetes_listResources({ kind: "Deployment", namespace: "my-service" })

Getting Resource Details

Get pod details

kubernetes_getResource({ kind: "Pod", name: "my-service-abc123", namespace: "my-service" })

Get service endpoints

kubernetes_getResource({ kind: "Service", name: "my-service", namespace: "my-service" })

Common Resources

Resource Use Case

Pod Check running containers, logs

Deployment Verify replicas, rollout status

Service Check endpoints, ports

ConfigMap Read configuration values

Secret Verify secret existence (not values)

PersistentVolumeClaim Check storage provisioning

Cluster Database cluster status (CloudNative-PG)

Infrastructure Verification

Verify database is ready

kubernetes_getResource({ kind: "Cluster", name: "my-db", namespace: "my-service" })

Check: status.phase == "Cluster in healthy state"

Verify Redis is running

kubernetes_listResources({ kind: "Pod", namespace: "my-service", labelSelector: "app=redis" })

Best Practices

• Always specify namespace - Avoid cluster-wide queries

• Check status fields - Not just existence

• Use label selectors - Filter relevant resources

• Verify before proceeding - Wait for Ready status
