Kai - Kubernetes MCP Server

A Model Context Protocol (MCP) server for managing Kubernetes clusters through LLM clients like Claude and Ollama.

Overview

Kai provides a bridge between large language models (LLMs) and your Kubernetes clusters, enabling natural language interaction with Kubernetes resources. The server exposes a comprehensive set of tools for managing clusters, namespaces, pods, deployments, services, and other Kubernetes resources.

Features

Core Workloads

• Pods - Create, list, get, delete, and stream logs
• Deployments - Create, list, describe, and update
• Jobs - Batch workload management (create, get, list, delete)
• CronJobs - Scheduled batch workloads (create, get, list, delete)

Networking

• Services - Create, get, list, and delete
• Ingress - HTTP/HTTPS routing, TLS configuration (create, get, list, update, delete)

Configuration

• ConfigMaps - Configuration management (create, get, list, update, delete)
• Secrets - Secret management (create, get, list, update, delete)
• Namespaces - Namespace management (create, get, list, delete)

Cluster Operations

• Context Management - Switch contexts, list contexts, rename, delete
• Nodes - Node monitoring, cordoning, and draining
• Cluster Health - Cluster status and resource metrics

Storage

• Persistent Volumes - PV and PVC management
• Storage Classes - Storage class operations

Security

• RBAC - Roles, RoleBindings, and ServiceAccounts

Advanced

• Custom Resources - CRD and custom resource operations
• Utilities - Port forwarding, events, and API exploration

Requirements

The server connects to your current kubectl context by default. Ensure you have access to a Kubernetes cluster configured for kubectl (e.g., minikube, Rancher Desktop, kind, EKS, GKE, AKS).

Installation

go install github.com/basebandit/kai/cmd/kai@latest

Configuration

Claude for Desktop

Edit your Claude Desktop configuration:

# macOS
code ~/Library/Application\ Support/Claude/claude_desktop_config.json

# Linux
code ~/.config/Claude/claude_desktop_config.json

Add the server configuration:

{
  "mcpServers": {
    "kubernetes": {
      "command": "/path/to/kai"
    }
  }
}

Custom Kubeconfig

By default, Kai uses ~/.kube/config. The server automatically loads your current context on startup.

Usage Examples

Once configured, you can interact with your cluster using natural language:

• "List all pods in the default namespace"
• "Create a deployment named nginx with 3 replicas using the nginx:latest image"
• "Show me the logs for pod my-app"
• "Delete the service named backend"
• "Create a cronjob that runs every 5 minutes"
• "Create an ingress for my-app with TLS enabled"
