Claude Code Integration

Use Claude Code’s AI capabilities to manage multiple Kubernetes clusters simultaneously with natural language.

Overview

klaude is an AI-powered kubectl plugin designed for managing multiple clusters simultaneously. It integrates with Claude Code, enabling you to:

Query Kubernetes resources across multiple clusters using natural language
Diagnose pod issues (CrashLoopBackOff, OOMKilled, pending pods)
Analyze RBAC permissions for any subject
Detect security misconfigurations
Monitor events and cluster health

Installation

Option 1: Homebrew (Recommended)

brew tap kubestellar/tap
brew install klaude

Option 2: Claude Code Plugin Marketplace

In Claude Code, run:

/plugin marketplace add kubestellar/claude-plugins

Then go to /plugin → Discover tab and install klaude.

Verify Installation

Run /mcp in Claude Code to see connected MCP servers:

plugin:klaude:klaude · ✓ connected

Configuration

Allow Tools Without Prompts

To avoid permission prompts for each tool call, add to ~/.claude/settings.json:

{
  "permissions": {
    "allow": [
      "mcp__plugin_klaude_klaude__*"
    ]
  }
}

Or run in Claude Code:

/allowed-tools add mcp__plugin_klaude_klaude__*

Slash Commands

The klaude plugin provides specialized slash commands for common Kubernetes operations:

/k8s-health

Check the health of all Kubernetes clusters in your kubeconfig.

/k8s-health

This will:

Discover all available clusters
Check health status of each cluster
Summarize any issues with recommended actions

/k8s-issues

Find all issues across your Kubernetes clusters.

/k8s-issues

Checks for:

Pod issues (CrashLoopBackOff, ImagePullBackOff, OOMKilled, pending)
Deployment issues (stuck rollouts, unavailable replicas)
Warning events

/k8s-analyze

Perform a comprehensive analysis of a Kubernetes namespace.

/k8s-analyze

Provides insights on:

Workload health (pods, deployments)
Resource usage and limits
Potential issues and recommendations

/k8s-rbac

Analyze RBAC permissions for any subject (user, group, or service account).

/k8s-rbac

Shows:

All RoleBindings and ClusterRoleBindings
Effective permissions
Overly permissive access warnings
Security recommendations

/k8s-security

Perform a security audit across all clusters.

/k8s-security

Finds:

Privileged containers
Containers running as root
Host network/PID/IPC usage
Pods without resource limits
Security misconfigurations

/k8s-audit-kubeconfig

Audit your kubeconfig and clean up stale clusters.

/k8s-audit-kubeconfig

Shows:

Which clusters are accessible (with versions)
Which clusters are inaccessible
Cleanup commands for stale configurations

Usage Examples installed, ask Claude questions like:

Cluster Management

“List my Kubernetes clusters”
“Check cluster health”
“Show me nodes in the production cluster”
“Audit my kubeconfig for stale clusters”

Workload Diagnostics

“Find pods with issues in the production namespace”
“Show me CrashLoopBackOff pods”
“What’s wrong with the frontend deployment?”
“Get logs from the api-server pod”

RBAC Analysis

“What permissions does the admin service account have?”
“Can I create deployments in the default namespace?”
“Show me all cluster roles”
“Analyze RBAC for user john@example.com”

Security

“Check for security misconfigurations in my cluster”
“Find pods running as root”
“Show me containers with privileged access”
“Check resource limits across namespaces”

Events and Monitoring

“Show me warning events in kube-system”
“What events happened in the last hour?”
“Analyze the production namespace”
