Kubectl MCP Server

Control your entire Kubernetes infrastructure through natural language conversations with AI.

Talk to your clusters like you talk to a DevOps expert. Debug crashed pods, optimize costs, deploy applications, audit security, manage Helm charts, and visualize dashboards, all through natural language in your favorite AI assistant or agents.

Installation

Quick Start with npx (Recommended - Zero Install)

# Run directly without installation - works instantly!
npx -y kubectl-mcp-server

# Or install globally for faster startup
npm install -g kubectl-mcp-server

Or install with pip (Python)

# Standard installation
pip install kubectl-mcp-server

# With interactive UI dashboards (recommended)
pip install kubectl-mcp-server[ui]

# Install kubectl-mcp-server
arctl mcp install io.github.rohitg00/kubectl-mcp-server

Available via: PyPI (uvx), npm (npx), OCI (docker.io/rohitghumare64/kubectl-mcp-server)

agentgateway

Route to multiple MCP servers through agentgateway:

# Start with streamable-http
kubectl-mcp-server --transport streamable-http --port 8000

# Configure gateway
cat > gateway.yaml <<EOF
binds:
- port: 3000
  listeners:
  - routes:
    - backends:
      - mcp:
          targets:
          - name: kubectl-mcp-server
            mcp:
              host: http://localhost:8000/mcp
EOF

# Start gateway
agentgateway --config gateway.yaml

Connect clients to http://localhost:3000/mcp for unified access to all 224 tools.

In-Cluster Deployment

Option 1: kMCP (Recommended)

Deploy with kMCP - a control plane for MCP servers:

# Install kMCP
curl -fsSL https://raw.githubusercontent.com/kagent-dev/kmcp/refs/heads/main/scripts/get-kmcp.sh | bash
kmcp install

# Deploy kubectl-mcp-server (easiest)
kmcp deploy package --deployment-name kubectl-mcp-server \
   --manager npx --args kubectl-mcp-server

# Or with Docker image
kmcp deploy --file deploy/kmcp/kmcp.yaml --image rohitghumare64/kubectl-mcp-server:latest

See kMCP quickstart for details.

Option 2: Standard Kubernetes

Deploy with kubectl/kustomize:

# Using kustomize (recommended)
kubectl apply -k deploy/kubernetes/

# Or individual manifests
kubectl apply -f deploy/kubernetes/namespace.yaml
kubectl apply -f deploy/kubernetes/rbac.yaml
kubectl apply -f deploy/kubernetes/deployment.yaml
kubectl apply -f deploy/kubernetes/service.yaml

# Access via port-forward
kubectl port-forward -n kubectl-mcp svc/kubectl-mcp-server 8000:8000

See deploy/ directory for all manifests and configuration options.

Option 3: kagent (AI Agent Framework)

Integrate with kagent - a CNCF Kubernetes-native AI agent framework:

# Install kagent
brew install kagent
kagent install --profile demo

# Register as ToolServer
kubectl apply -f deploy/kagent/toolserver-stdio.yaml

# Open dashboard
kagent dashboard

Your AI agents now have access to all 224 Kubernetes tools. See kagent quickstart.

Multi-Cluster Support

Seamlessly manage multiple Kubernetes clusters through natural language. Every tool supports an optional context parameter to target any cluster without switching contexts.

Context Parameter (v1.15.0)

All 224 tools accept an optional context parameter to target specific clusters:

Talk to your AI assistant:

"List pods in the production cluster"
"Get deployments from staging context"
"Show logs from the api-pod in the dev cluster"
"Compare namespaces between production and staging clusters"

Direct tool calls with context:

# Target a specific cluster context
kubectl-mcp-server call get_pods '{"namespace": "default", "context": "production"}'

# Get deployments from staging
kubectl-mcp-server call get_deployments '{"namespace": "app", "context": "staging"}'

# Install Helm chart to production cluster
kubectl-mcp-server call install_helm_chart '{"name": "redis", "chart": "bitnami/redis", "namespace": "cache", "context": "production"}'

# Compare resources across clusters
kubectl-mcp-server call compare_namespaces '{"namespace1": "prod-ns", "namespace2": "staging-ns", "context": "production"}'

Context Management

Talk to your AI assistant:

"List all available Kubernetes contexts"
"Switch to the production cluster"
"Show me details about the staging context"
"What's the current cluster I'm connected to?"

Or use the CLI directly:

kubectl-mcp-server context                    # Show current context
kubectl-mcp-server context production         # Switch context
kubectl-mcp-server call list_contexts_tool    # List all contexts via MCP

How It Works

• If context is omitted, the tool uses your current kubectl context
• If context is specified, the tool targets that cluster directly
• Response includes "context": "production" or "context": "current" for clarity
• Works with all kubeconfig setups and respects KUBECONFIG environment variable
• No need to switch contexts for cross-cluster operations
