Kube MCP

A Model Context Protocol (MCP) server for Kubernetes cluster management. Enables AI assistants to interact with Kubernetes resources.

Quick Start

npx @icy-r/kube-mcp

MCP Configuration

Add to your MCP client (Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "kubernetes": {
      "command": "npx",
      "args": ["-y", "@icy-r/kube-mcp"],
      "env": {
        "KUBEMCP_DEFAULT_NAMESPACE": "default"
      }
    }
  }
}

Custom kubeconfig:

{
  "mcpServers": {
    "kubernetes": {
      "command": "npx",
      "args": ["-y", "@icy-r/kube-mcp"],
      "env": {
        "KUBEMCP_CONFIG_SOURCE": "custom",
        "KUBEMCP_KUBECONFIG_PATH": "/path/to/kubeconfig"
      }
    }
  }
}

Safety Features

Destructive actions require explicit confirmation:

{ "action": "delete", "name": "my-pod", "confirm": true }

Preview changes with dry-run:

{ "action": "scale", "name": "my-deployment", "replicas": 5, "dryRun": true }
