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

1. Always specify namespace - Avoid cluster-wide queries
2. Check status fields - Not just existence
3. Use label selectors - Filter relevant resources
4. Verify before proceeding - Wait for Ready status
