Installation & Usage

Prerequisites

Before using this MCP server with any tool, make sure you have:

1. kubectl installed and in your PATH
2. A valid kubeconfig file with contexts configured
3. Access to a Kubernetes cluster configured for kubectl (e.g. minikube, Rancher Desktop, GKE, etc.)
4. Helm v3 installed and in your PATH (no Tiller required). Optional if you don't plan to use Helm.

You can verify your connection by running kubectl get pods in a terminal to ensure you can connect to your cluster without credential issues.

By default, the server loads kubeconfig from ~/.kube/config. For additional authentication options (environment variables, custom paths, etc.), see ADVANCED_README.md.

Claude Code

Add the MCP server to Claude Code using the built-in command:

claude mcp add kubernetes -- npx mcp-server-kubernetes

This will automatically configure the server in your Claude Code MCP settings.

Codex

Add the MCP server to Codex CLI using the built-in command:

codex mcp add kubernetes -- npx mcp-server-kubernetes

This registers the server globally in ~/.codex/config.toml and makes its tools available in all Codex sessions.

Claude Desktop

Add the following configuration to your Claude Desktop config file:

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

Claude Desktop Connector via mcpb

MCP Server Kubernetes is also available as a mcpb (formerly dxt) extension. In Claude Desktop, go to Settings (Cmd+, on Mac) -> Extensions -> Browse Extensions and scroll to find mcp-server-kubernetes in the modal. Install it & it will install & utilize kubectl via command line & your kubeconfig.

To manually install, you can also get the .mcpb by going to the latest Release and downloading it.

VS Code

For VS Code integration, you can use the MCP server with extensions that support the Model Context Protocol:

1. Install a compatible MCP extension (such as Claude Dev or similar MCP clients)
2. Configure the extension to use this server:

{
  "mcpServers": {
    "kubernetes": {
      "command": "npx",
      "args": ["mcp-server-kubernetes"],
      "description": "Kubernetes cluster management and operations"
    }
  }
}

Cursor

Cursor supports MCP servers through its AI integration. Add the server to your Cursor MCP configuration:

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

The server will automatically connect to your current kubectl context. You can verify the connection by asking the AI assistant to list your pods or create a test deployment.

Usage with mcp-chat

mcp-chat is a CLI chat client for MCP servers. You can use it to interact with the Kubernetes server.

npx mcp-chat --server "npx mcp-server-kubernetes"

Alternatively, pass it your existing Claude Desktop configuration file from above (Linux should pass the correct path to config):

Mac:

npx mcp-chat --config "~/Library/Application Support/Claude/claude_desktop_config.json"

Windows:

npx mcp-chat --config "%APPDATA%\Claude\claude_desktop_config.json"
