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"
      }
    }
  }
}

Environment Variables

| Variable | Description | Default | |----------|-------------|---------| | KUBEMCP_CONFIG_SOURCE | local or custom | local | | KUBEMCP_KUBECONFIG_PATH | Custom kubeconfig path | - | | KUBEMCP_DEFAULT_NAMESPACE | Default namespace | default | | KUBEMCP_RESPONSE_FORMAT | json, toon, auto | auto |

Tools

| Tool | Actions | |------|---------| | k8s_deployments | list, get, scale, restart, get_status, get_metrics | | k8s_pods | list, get, delete, get_logs, summarize_logs, get_status | | k8s_services | list, get, get_endpoints | | k8s_configmaps | list, get, create, update, delete | | k8s_secrets | list, get, create, update, delete | | k8s_namespaces | list, get, create, delete | | k8s_metrics | get_pod_metrics, get_node_metrics | | k8s_events | list, get_resource_events, get_recent_events | | k8s_audit | get_config, configure, get_session_log, clear_session_log |

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 }
