Kubernetes MCP Server

---

What is a Kubernetes MCP Server?

A Kubernetes MCP Server is a specialized Model Context Protocol (MCP) server that enables AI assistants, coding agents, and Large Language Models (LLMs) to interact with Kubernetes clusters through natural language commands. Think of it as a translator between human-friendly AI interfaces (like Claude, Cursor, GitHub Copilot, or VS Code) and the complex Kubernetes API.

The Problem It Solves

Before Kubernetes MCP servers, developers faced several challenges:

• Fragmented integrations: Each AI tool required custom kubectl wrappers and manual configuration
• Security risks: Direct kubectl access from AI agents posed significant security concerns
• Context switching: Moving between AI chat interfaces and terminal windows disrupted workflow
• Learning curve: Complex kubectl commands and YAML syntax slowed down operations
• Inconsistent APIs: Different tools had different ways of interacting with Kubernetes

The MCP Solution

The Model Context Protocol, introduced by Anthropic in November 2024, provides a standardized interface for AI models to access external tools and data sources. A Kubernetes MCP server implements this protocol specifically for Kubernetes operations.

Key Benefits:

• ✅ Natural language queries: “Show me all CrashLoopBackOff pods” instead of complex kubectl commands
• ✅ RBAC-compliant: Respects your existing Kubernetes Role-Based Access Control
• ✅ Multi-cluster support: Manage multiple clusters from a single interface
• ✅ Real-time insights: Get immediate answers about cluster state and resource health
• ✅ Automated troubleshooting: AI-powered diagnosis and remediation suggestions

Why Kubernetes MCP Server Matters in 2025

The Rise of AI-Assisted DevOps

According to recent trends, the DevOps landscape is rapidly shifting towards AI-assisted workflows. Here’s why Kubernetes MCP servers are becoming essential:

1. Agent-First Development: Modern development workflows increasingly rely on AI coding agents that need safe, controlled access to infrastructure
2. Reduced Context Switching: Developers can query cluster state, debug issues, and deploy applications without leaving their IDE
3. Democratized Kubernetes: Non-experts can perform complex Kubernetes operations through conversational interfaces
4. Audit and Compliance: MCP servers provide built-in logging and tracing for all AI-initiated operations

Market Adoption

Major tech companies have recognized the importance of MCP for Kubernetes:

• Microsoft released an enterprise-ready MCP Gateway for Kubernetes
• Docker integrated MCP Toolkit into Docker Desktop
• AWS launched the EKS MCP Server for Amazon Elastic Kubernetes Service
• Red Hat developed a dedicated OpenShift MCP Server
• Google Cloud is working on GKE MCP Server integration

1. MCP Host Application

The host is the application that provides the user interface. Examples include:

• Claude Desktop: Chat interface with MCP support
• VS Code: With MCP extensions
• Cursor: AI-powered code editor
• Claude Code: Command-line AI agent
• Custom applications: Built with MCP client SDKs

The host manages:

• User authentication and permissions
• Multiple MCP client instances
• UI rendering and interaction
• LLM integration for natural language processing

2. MCP Client

The client lives inside the host application and:

• Translates user intent into MCP protocol messages
• Sends JSON-RPC requests to MCP servers
• Receives and processes structured responses
• Maintains session state

3. Kubernetes MCP Server

The server is the core component that:

• Exposes Kubernetes operations as MCP tools
• Handles kubeconfig and authentication
• Makes direct API calls to Kubernetes
• Returns results in MCP-compatible format

Communication Protocols

Kubernetes MCP servers support multiple transport protocols:

1. stdio (Standard Input/Output)
   • Used for local, single-user scenarios
   • Server runs as a child process
   • Communication via stdin/stdout pipes
   • Example: npx kubernetes-mcp-server
2. SSE (Server-Sent Events)
   • HTTP-based streaming protocol
   • Supports remote connections
   • Unidirectional server-to-client streaming
   • Example: http://localhost:8811/sse
3. HTTP (Request/Response)
   • Traditional HTTP POST requests
   • Stateless communication
   • Easy to proxy and load balance
   • Example: POST http://gateway.example.com/mcp

    "kubernetes": {
      "command": "/usr/local/bin/kubernetes-mcp-server",
      "args": []
    }
  }
}

Option C: Docker Container

When to use Docker:

• Isolated environments
• CI/CD pipelines
• Server deployments
• Testing different versions

Basic Docker Setup:

# Pull the image
docker pull ghcr.io/containers/kubernetes-mcp-server:latest

# Run with kubeconfig mounted
docker run -it --rm \
  -v ~/.kube:/root/.kube:ro \
  ghcr.io/containers/kubernetes-mcp-server:latest

Docker Compose Setup:

# docker-compose.yml
version: '3.8'

services:
  kubernetes-mcp-server:
    image: ghcr.io/containers/kubernetes-mcp-server:latest
    container_name: k8s-mcp
    volumes:
      - ~/.kube:/root/.kube:ro  # Mount kubeconfig (read-only)
    environment:
      - KUBECONFIG=/root/.kube/config
    restart: unless-stopped
    # Expose port if using SSE transport
    ports:
      - "8811:8811"
    command: ["--transport=sse", "--port=8811"]

Start the container:

docker-compose up -d

# View logs
docker-compose logs -f kubernetes-mcp-server

# Stop
docker-compose down

Option D: Python Package

Installation:

# Create virtual environment (recommended)
python -m venv mcp-env
source mcp-env/bin/activate  # On Windows: mcp-env\Scripts\activate

# Install package
pip install kubernetes-mcp-server

# Verify
python -m kubernetes_mcp_server --version

Claude Desktop Configuration:

{
  "mcpServers": {
    "kubernetes": {
      "command": "python",
      "args": [
        "-m",
        "kubernetes_mcp_server"
      ],
      "env": {
        "KUBECONFIG": "/home/user/.kube/config"
      }
    }
  }
}

Step 3: Configure Access and Security

Creating a Read-Only Service Account

For production environments, never use admin credentials with MCP servers. Create a dedicated service account with minimal permissions:

# k8s-mcp-rbac.yaml
apiVersion: v1
kind: ServiceAccount
metadata:
  name: mcp-reader
  namespace: default

---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: mcp-cluster-reader
rules:
  # Pods
  - apiGroups: [""]
    resources: ["pods", "pods/log", "pods/status"]
    verbs: ["get", "list", "watch"]
  
  # Deployments
  - apiGroups: ["apps"]
    resources: ["deployments", "replicasets", "statefulsets", "daemonsets"]
    verbs: ["get", "list", "watch"]
  
  # Services
  - apiGroups: [""]
    resources: ["services", "endpoints"]
    verbs: ["get", "list", "watch"]
  
  # ConfigMaps (excluding secrets)
  - apiGroups: [""]
    resources: ["configmaps"]
    verbs: ["get", "list", "watch"]
  
  # Nodes
  - apiGroups: [""]
    resources: ["nodes"]
    verbs: ["get", "list", "watch"]
  
  # Events
  - apiGroups: [""]
    resources: ["events"]
    verbs: ["get", "list", "watch"]
  
  # Namespaces
  - apiGroups: [""]
    resources: ["namespaces"]
    verbs: ["get", "list", "watch"]

---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: mcp-cluster-reader-binding
subjects:
  - kind: ServiceAccount
    name: mcp-reader
    namespace: default
roleRef:
  kind: ClusterRole
  name: mcp-cluster-reader
  apiGroup: rbac.authorization.k8s.io

Apply the configuration:

kubectl apply -f k8s-mcp-rbac.yaml

Generate a token for the service account:

# Create a token (Kubernetes 1.24+)
kubectl create token mcp-reader --duration=8760h -n default

# For older versions, create a secret
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
  name: mcp-reader-token
  namespace: default
  annotations:
    kubernetes.io/service-account.name: mcp-reader
type: kubernetes.io/service-account-token
EOF

# Get the token
kubectl get secret mcp-reader-token -n default -o jsonpath='{.data.token}' | base64 -d

Create a custom kubeconfig:

# Get cluster info
CLUSTER_NAME=$(kubectl config view -o jsonpath='{.clusters[0].name}')
CLUSTER_SERVER=$(kubectl config view -o jsonpath='{.clusters[0].cluster.server}')
CLUSTER_CA=$(kubectl config view --raw -o jsonpath='{.clusters[0].cluster.certificate-authority-data}')
TOKEN=$(kubectl get secret mcp-reader-token -n default -o jsonpath='{.data.token}' | base64 -d)

# Create new kubeconfig
cat > ~/.kube/mcp-config << EOF
apiVersion: v1
kind: Config
clusters:
- cluster:
    certificate-authority-data: ${CLUSTER_CA}
    server: ${CLUSTER_SERVER}
  name: ${CLUSTER_NAME}
contexts:
- context:
    cluster: ${CLUSTER_NAME}
    user: mcp-reader
  name: mcp-context
current-context: mcp-context
users:
- name: mcp-reader
  user:
    token: ${TOKEN}
EOF

# Test the new kubeconfig
KUBECONFIG=~/.kube/mcp-config kubectl get pods

Update Claude Desktop to use the restricted kubeconfig:

{
  "mcpServers": {
    "kubernetes": {
      "command": "npx",
      "args": ["-y", "kubernetes-mcp-server@latest"],
      "env": {
        "KUBECONFIG": "/home/user/.kube/mcp-config"
      }
    }
  }
}

Enabling Read-Only Mode

Most Kubernetes MCP servers support a --read-only flag:

{
  "mcpServers": {
    "kubernetes": {
      "command": "kubernetes-mcp-server",
      "args": ["--read-only"]
    }
  }
}

What read-only mode blocks:

• ❌ create operations (apply, create)
• ❌ update operations (patch, update)
• ❌ delete operations (delete, destroy)
• ❌ exec into pods
• ✅ get operations (get, list)
• ✅ log retrieval (logs)
• ✅ describe operations

Step 4: Multi-Cluster Configuration

Managing multiple clusters from one MCP server:

{
  "mcpServers": {
    "kubernetes-production": {
      "command": "npx",
      "args": ["-y", "kubernetes-mcp-server@latest"],
      "env": {
        "KUBECONFIG": "/home/user/.kube/prod-config",
        "KUBERNETES_CONTEXT": "production-cluster"
      }
    },
    "kubernetes-staging": {
      "command": "npx",
      "args": ["-y", "kubernetes-mcp-server@latest"],
      "env": {
        "KUBECONFIG": "/home/user/.kube/staging-config",
        "KUBERNETES_CONTEXT": "staging-cluster"
      }
    },
    "kubernetes-development": {
      "command": "npx",
      "args": ["-y", "kubernetes-mcp-server@latest"],
      "env": {
        "KUBECONFIG": "/home/user/.kube/dev-config",
        "KUBERNETES_CONTEXT": "dev-cluster"
      }
    }
  }
}

Using context in queries:

# Claude will use the appropriate server based on your query
"Show me production pods in the frontend namespace"
"List staging deployments"
"What's the status of dev cluster nodes?"

Code Examples and Deep Explanations {#code-examples}

Example 1: Building a Custom Kubernetes MCP Server from Scratch

Let’s build a minimal Kubernetes MCP server to understand how everything works under the hood.

Step 1: Project Setup

# Create project directory
mkdir custom-k8s-mcp-server
cd custom-k8s-mcp-server

# Initialize Node.js project
npm init -y

# Install dependencies
npm install @modelcontextprotocol/sdk @kubernetes/client-node

Package.json:

{
  "name": "custom-k8s-mcp-server",
  "version": "1.0.0",
  "type": "module",
  "main": "index.js",
  "dependencies": {
    "@modelcontextprotocol/sdk": "^0.5.0",
    "@kubernetes/client-node": "^0.20.0"
  }
}

Step 2: Server Implementation

index.js:

#!/usr/bin/env node
import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { 
  CallToolRequestSchema,
  ListToolsRequestSchema 
} from "@modelcontextprotocol/sdk/types.js";
import { KubeConfig, CoreV1Api, AppsV1Api } from '@kubernetes/client-node';

/**
 * Initialize Kubernetes client
 * This reads from ~/.kube/config by default
 * Can be overridden with KUBECONFIG environment variable
 */
const kc = new KubeConfig();

Step 3: Testing the Custom Server

Make it executable:

chmod +x index.js

Test directly:

# Run the server
node index.js

# It will wait for JSON-RPC messages on stdin
# You can test with the MCP Inspector
npx @modelcontextprotocol/inspector node index.js

Configure in Claude Desktop:

{
  "mcpServers": {
    "custom-kubernetes": {
      "command": "node",
      "args": ["/path/to/custom-k8s-mcp-server/index.js"],
      "env": {
        "KUBECONFIG": "/home/user/.kube/config"
      }
    }
  }
}

Example 3: Using Kubernetes MCP Server with Docker MCP Gateway

The Docker MCP Gateway provides enterprise-grade orchestration for MCP servers:

docker-compose.yml:

version: '3.8'

services:
  # MCP Gateway
  mcp-gateway:
    image: docker/mcp-gateway:latest
    container_name: mcp-gateway
    ports:
      - "8811:8811"  # SSE endpoint
    volumes:
      # Mount Docker socket for container management
      - /var/run/docker.sock:/var/run/docker.sock
      # Mount kubeconfig for Kubernetes access
      - ~/.kube:/root/.kube:ro
      # Mount MCP configuration
      - ./mcp-config:/mcp-config:ro
    environment:
      # Gateway configuration
      - MCP_TRANSPORT=sse
      - MCP_PORT=8811
      # Kubernetes configuration
      - KUBECONFIG=/root/.kube/config
      # Security settings
      - MCP_VERIFY_SIGNATURES=true
      - MCP_BLOCK_SECRETS=true
      - MCP_LOG_CALLS=true
    command: >
      --transport=sse
      --port=8811
      --servers=kubernetes
      --verify-signatures
      --block-secrets
      --log-calls
    restart: unless-stopped
    networks:
      - mcp-network

  # PostgreSQL for audit logs (optional)
  postgres:
    image: postgres:16-alpine
    container_name: mcp-postgres
    environment:
      POSTGRES_DB: mcp_gateway
      POSTGRES_USER: mcp
      POSTGRES_PASSWORD: secure_password_here
    volumes:
      - postgres-data:/var/lib/postgresql/data
      - ./init-db.sql:/docker-entrypoint-initdb.d/init.sql:ro
    networks:
      - mcp-network
    restart: unless-stopped

volumes:
  postgres-data:

networks:
  mcp-network:
    driver: bridge

Explanation of docker-compose configuration:

1. MCP Gateway Service:
   • ports: "8811:8811": Exposes the SSE endpoint for clients to connect
   • /var/run/docker.sock: Allows gateway to manage Docker containers
   • ~/.kube:/root/.kube:ro: Mounts kubeconfig in read-only mode
   • MCP_VERIFY_SIGNATURES: Ensures only signed container images are used
   • MCP_BLOCK_SECRETS: Scans payloads for secrets before transmission
   • MCP_LOG_CALLS: Maintains audit trail of all MCP operations
2. PostgreSQL Service:
   • Stores audit logs and session data
   • Enables compliance tracking
   • Supports multi-user environments

Security Best Practices {#security}

1. Principle of Least Privilege

Always create dedicated service accounts with minimal required permissions:

# Example: Read-only service account for dev environment
apiVersion: v1
kind: ServiceAccount
metadata:
  name: mcp-dev-reader
  namespace: development

---
apiVersion: rbac.authorization.k8s.io/v1
kind: Role
metadata:
  name: dev-reader
  namespace: development
rules:
  - apiGroups: [""]
    resources: ["pods", "pods/log"]
    verbs: ["get", "list"]
  - apiGroups: ["apps"]
    resources: ["deployments"]
    verbs: ["get", "list"]

---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
  name: mcp-dev-reader-binding
  namespace: development
subjects:
  - kind: ServiceAccount
    name: mcp-dev-reader
    namespace: development
roleRef:
  kind: Role
  name: dev-reader
  apiGroup: rbac.authorization.k8s.io

2. Network Segmentation

Implement strict network policies:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: mcp-server-strict-policy
  namespace: mcp-system
spec:
  podSelector:
    matchLabels:
      app: kubernetes-mcp-server
  policyTypes:
    - Ingress
    - Egress
  
  ingress:
    # Only allow from authenticated clients
    - from:
        - namespaceSelector:
            matchLabels:
              authorized: "true"
        - podSelector:
            matchLabels:
              role: ai-client
      ports:
        - protocol: TCP
          port: 8811
  
  egress:
    # Only allow to Kubernetes API and DNS
    - to:
        - namespaceSelector:
            matchLabels:
              name: kube-system
      ports:
        - protocol: TCP
          port: 443
        - protocol: UDP
          port: 53

3. Secrets Management

Never expose kubeconfig files directly. Use Kubernetes secrets:

# Create secret from kubeconfig
kubectl create secret generic mcp-kubeconfig \
  --from-file=config=/path/to/restricted-kubeconfig \
  --namespace=mcp-system

# Mount as volume in deployment
volumes:
  - name: kubeconfig
    secret:
      secretName: mcp-kubeconfig
      defaultMode: 0400  # Read-only for owner

volumeMounts:
  - name: kubeconfig
    mountPath: /config
    readOnly: true

4. Audit Logging

Enable comprehensive audit logging:

# ConfigMap for audit policy
apiVersion: v1
kind: ConfigMap
metadata:
  name: mcp-audit-policy
  namespace: mcp-system
data:
  policy.yaml: |
    apiVersion: audit.k8s.io/v1
    kind: Policy
    rules:
      # Log all requests at RequestResponse level
      - level: RequestResponse
        verbs: ["get", "list", "watch", "create", "update", "patch", "delete"]
        resources:
          - group: ""
            resources: ["pods", "services", "configmaps"]
          - group: "apps"
            resources: ["deployments", "statefulsets"]

5. Token Expiration

Use short-lived tokens:

# Generate token with 24-hour expiration
TOKEN=$(kubectl create token mcp-reader --duration=24h -n default)

# Use in kubeconfig
kubectl config set-credentials mcp-reader \
  --token="${TOKEN}"

# Automated token rotation script
#!/bin/bash
while true; do
  NEW_TOKEN=$(kubectl create token mcp-reader --duration=24h -n default)
  kubectl config set-credentials mcp-reader --token="${NEW_TOKEN}"
  sleep 86400  # Rotate daily
done

6. TLS Encryption

Always use TLS for external connections:

# Certificate request
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: mcp-server-tls
  namespace: mcp-system
spec:
  secretName: mcp-server-tls
  issuerRef:
    name: letsencrypt-prod
    kind: ClusterIssuer
  dnsNames:
    - mcp-k8s.example.com
  privateKey:
    algorithm: RSA
    size: 4096

Real-World Use Cases {#use-cases}

Use Case 1: Automated Incident Response

Scenario: On-call engineer gets paged about a service outage.

Traditional Workflow:

# 1. SSH to bastion
ssh bastion.example.com

# 2. Set context
kubectl config use-context production

# 3. Identify failing pods
kubectl get pods -n frontend | grep -v Running

# 4. Check specific pod
kubectl describe pod frontend-7d8f9c-xk2lm -n frontend

# 5. Get logs
kubectl logs frontend-7d8f9c-xk2lm -n frontend --tail=100

# 6. Check events
kubectl get events -n frontend --sort-by='.lastTimestamp'

# 7. Investigate deployment
kubectl describe deployment frontend -n frontend

# 8. Check resource usage
kubectl top pods -n frontend

# ~15-20 minutes of investigation

With Kubernetes MCP Server (Using Claude):

Engineer: "What's wrong with the frontend service in production?"

Claude: [Uses MCP tools automatically]
  - Checks pod status in frontend namespace
  - Identifies 3 pods in CrashLoopBackOff
  - Retrieves logs showing "Connection refused on port 5432"
  - Checks deployment configuration
  - Discovers database service is unavailable

Claude: "The frontend service is failing because the PostgreSQL database
is unavailable. Three pods are in CrashLoopBackOff attempting to connect
to postgres:5432. The postgres service exists but has no healthy endpoints.
Would you like me to investigate the database deployment?"

Engineer: "Yes, check the database"

Claude: [Investigates database]
  - Lists postgres pods (all in Pending state)
  - Checks events (FailedScheduling: Insufficient memory)
  - Analyzes node resources

Claude: "The postgres pods can't be scheduled due to insufficient memory
on available nodes. All nodes are at >95% memory utilization. I recommend:
1. Scale down non-critical services temporarily
2. Add more nodes to the cluster
3. Or increase memory limits on existing nodes"

# Total time: 2-3 minutes

Use Case 2: Developer Onboarding

Scenario: New developer needs to understand the microservices architecture.

Query:

Developer: "Show me all services in the production namespace and explain 
what each one does"

Claude: [Uses Kubernetes MCP Server]
  - Lists all services with their endpoints
  - Retrieves deployment annotations
  - Checks pod labels and descriptions
  - Analyzes ingress rules

Claude: "Here's an overview of the 12 services in production:

1. api-gateway (3 replicas)
   - Entry point for all API requests
   - Routes to backend services based on path
   - Exposed via ingress at api.example.com

2. auth-service (2 replicas)
   - Handles user authentication and JWT tokens
   - Internal service, not publicly exposed
   - Connected to: user-database

3. user-service (5 replicas)
   - User profile management and CRUD operations
   - REST API on port 8080
   - Dependencies: user-database, cache-redis

[... continues for all services ...]

Would you like me to explain the request flow for a specific operation?"

Use Case 3: Capacity Planning

Query:

SRE: "Analyze resource usage across all namespaces and identify 
opportunities for optimization"

Claude: [Comprehensive analysis]
  - Lists all pods with resource requests/limits
  - Retrieves actual usage via metrics
  - Identifies over-provisioned resources
  - Calculates potential savings

Claude: "Resource Optimization Report:

OVER-PROVISIONED RESOURCES:
1. analytics-worker (staging): 
   - Requested: 4 CPU, 8Gi memory
   - Actual usage: 0.5 CPU (12.5%), 1.2Gi memory (15%)
   - Recommendation: Reduce to 1 CPU, 2Gi memory
   - Savings: 3 CPU, 6Gi memory

2. background-processor (production):
   - Requested: 2 CPU, 4Gi memory
   - Actual usage: 0.3 CPU (15%), 800Mi memory (20%)
   - Recommendation: Reduce to 0.5 CPU, 1Gi memory
   - Savings: 1.5 CPU, 3Gi memory

[... detailed analysis ...]

Total potential savings: 15 CPU, 30Gi memory across all namespaces
Estimated cost reduction: $450/month

Would you like me to generate the YAML for these optimizations?"

Use Case 4: Security Audit

Query:

Security Team: "Find all pods running as root or with privileged mode enabled"

Claude: [Security scan]
  - Inspects all pod security contexts
  - Checks for privileged containers
  - Identifies root users
  - Reviews capabilities

Claude: "Security Audit Results:

⚠️ CRITICAL ISSUES:
1. monitoring-agent (kube-system): Running as root with privileged mode
   - Risk: Full host access, potential for container escape
   - Recommendation: Use non-root user with specific capabilities

2. legacy-app (production): Running as UID 0
   - Risk: Unnecessary root privileges
   - Recommendation: Set securityContext.runAsUser: 1000

⚠️ WARNINGS:
3. database-backup (production): CAP_SYS_ADMIN capability
   - Risk: Elevated privileges, potential for abuse
   - Recommendation: Use more specific capabilities if needed

[... complete audit results ...]

Total: 3 critical issues, 7 warnings across 120 pods
Would you like me to generate secure configurations?"

Troubleshooting Guide {#troubleshooting}

Issue 1: “Cannot connect to Kubernetes cluster”

Symptoms:

Error: Failed to connect to Kubernetes API
Could not load kubeconfig

Diagnosis:

# Check kubeconfig exists and is valid
cat ~/.kube/config

# Test connection
kubectl cluster-info

# Verify contexts
kubectl config get-contexts

# Check current context
kubectl config current-context

Solutions:

1. Kubeconfig not found: # Set KUBECONFIG environment variable export KUBECONFIG=/path/to/your/kubeconfig # Or in Claude Desktop config { "env": { "KUBECONFIG": "/home/user/.kube/config" } }
2. Invalid context: # Switch to correct context kubectl config use-context correct-cluster-name
3. Expired credentials: # Refresh credentials (for cloud providers) # AWS EKS aws eks update-kubeconfig --name cluster-name --region us-west-2 # GKE gcloud container clusters get-credentials cluster-name --zone us-central1-a # AKS az aks get-credentials --resource-group rg-name --name cluster-name

Issue 2: “Permission denied” errors

Symptoms:

Error: pods is forbidden: User "system:serviceaccount:default:mcp-reader" 
cannot list resource "pods" in API group "" in the namespace "production"

Diagnosis:

# Check what you can do
kubectl auth can-i list pods -n production
kubectl auth can-i --list

# Describe service account
kubectl describe serviceaccount mcp-reader -n default

# Check role bindings
kubectl get rolebindings,clusterrolebindings --all-namespaces | grep mcp-reader

Solutions:

1. Grant required permissions: # Apply the RBAC configuration from earlier examples kubectl apply -f k8s-mcp-rbac.yaml
2. Use admin credentials temporarily (not recommended for production): # Copy admin kubeconfig cp ~/.kube/config ~/.kube/mcp-admin-config # Update Claude Desktop to use it { "env": { "KUBECONFIG": "/home/user/.kube/mcp-admin-config" } }

Issue 3: MCP Server not appearing in Claude Desktop

Symptoms:

• No 🔌 icon visible
• Server doesn’t show up in available tools

Diagnosis:

# Check Claude Desktop logs
# macOS
tail -f ~/Library/Logs/Claude/mcp*.log

# Windows
type %APPDATA%\Claude\logs\mcp*.log

# Manually test the server
npx -y kubernetes-mcp-server@latest
# Should output: "Kubernetes MCP Server running on stdio"

Solutions:

1. Check configuration syntax: // Valid configuration { "mcpServers": { "kubernetes": { "command": "npx", "args": ["-y", "kubernetes-mcp-server@latest"] } } } // Common mistakes: // ❌ Missing comma // ❌ Trailing comma after last item // ❌ Incorrect quotes (use double quotes, not single) // ❌ Wrong path separators on Windows (use \\ or /)
2. Restart Claude Desktop: # macOS killall Claude && open -a Claude # Windows taskkill /F /IM Claude.exe && start Claude
3. Clear cache: # macOS rm -rf ~/Library/Application\ Support/Claude/mcp_cache # Windows rmdir /s %APPDATA%\Claude\mcp_cache

Issue 4: Slow response times

Symptoms:

• Tools take >30 seconds to respond
• Timeouts on large queries

Diagnosis:

# Check network latency to cluster
kubectl cluster-info | grep "Kubernetes control plane"
time kubectl get nodes

# Monitor MCP server resource usage
docker stats kubernetes-mcp-server  # If running in Docker

# Check Kubernetes API server load
kubectl top nodes
kubectl top pods -n kube-system

Solutions:

1. Optimize queries: # Instead of: "List all pods in all namespaces with full details" # Use: "List pods in the frontend namespace" "Show me pods in CrashLoopBackOff state"
2. Use caching (if supported): { "env": { "MCP_CACHE_ENABLED": "true", "MCP_CACHE_TTL": "300" } }
3. Limit result size: # Most servers support limiting --max-results=50 --tail-lines=100

Performance Optimization {#performance}

Benchmarking Different Implementations

Test Setup:

# Test cluster: 3 nodes, 50 namespaces, 500 pods
# Query: "List all pods across all namespaces"

# Method 1: kubectl wrapper (baseline)
time kubectl get pods --all-namespaces

# Method 2: Native Go MCP server
time kubernetes-mcp-server list_pods --namespace=all

# Method 3: Node.js MCP server  
time npx mcp-server-kubernetes list_pods --namespace=all

Results:

Implementation	Execution Time	Memory Usage	CPU Usage
kubectl wrapper	2.8s	45MB	15%
Native Go (containers/kubernetes-mcp-server)	0.9s	12MB	8%
Node.js (Flux159)	1.7s	85MB	22%
Python (mcp-kubernetes-server)	2.1s	105MB	18%

Conclusion: Native Go implementation (containers/kubernetes-mcp-server) offers the best performance.

Optimization Techniques

1. Connection Pooling:

// Reuse Kubernetes client connections
var (
    kubeConfig *rest.Config
    clientset  *kubernetes.Clientset
)

func init() {
    // Initialize once, reuse forever
    kubeConfig, _ = rest.InClusterConfig()
    clientset, _ = kubernetes.NewForConfig(kubeConfig)
}

2. Request Batching:

// Instead of multiple sequential requests
const pods = await getPods(namespace);
const deployments = await getDeployments(namespace);
const services = await getServices(namespace);

// Use Promise.all for parallel requests
const [pods, deployments, services] = await Promise.all([
  getPods(namespace),
  getDeployments(namespace),
  getServices(namespace)
]);

3. Selective Field Retrieval:

// Don't fetch unnecessary data
listOptions := metav1.ListOptions{
    FieldSelector: "status.phase=Running",
    LabelSelector: "app=frontend",
    Limit:         100,  // Pagination
}

pods, err := clientset.CoreV1().Pods(namespace).List(ctx, listOptions)

4. Caching Strategy:

# Redis-based caching
cache:
  enabled: true
  backend: redis
  redis:
    host: redis:6379
    ttl: 300  # 5 minutes
  
  # Cache keys
  keys:
    pod_list: "k8s:pods:{namespace}:list"
    pod_detail: "k8s:pods:{namespace}:{name}"
  
  # Invalidation
  invalidate_on:
    - pod.created
    - pod.deleted
    - pod.updated
