MCP Kubernetes

A Model Context Protocol (MCP) server for executing Kubernetes commands from Claude Desktop or any MCP-compatible client.

Security

This MCP server executes kubectl commands directly on your machine, so it should only be used in trusted environments. It does not implement authentication or authorization controls by default.

Installation

You can install this tool directly using Go:

go install github.com/BhagyaAmarasinghe/mcp-kubernetes@latest

Usage

Starting the server

Run the MCP Kubernetes server:

mcp-kubernetes

By default, the server runs using stdio transport. You can specify a different port for HTTP transport with the -port flag:

mcp-kubernetes -port 8080

Using with Claude Desktop

1. Configure Claude Desktop to use the MCP Kubernetes server by adding it to your claude_desktop_config.json:

{
  "mcpServers": {
    "kubernetes": {
      "command": "mcp-kubernetes"
    }
  }
}

2. You can now use Claude to execute Kubernetes commands, such as:
   • "Show me the pods in the default namespace"
   • "List all services across all namespaces"
   • "Check the status of my deployment named my-app"

Available Commands

The MCP Kubernetes server supports the following MCP requests:

execute

{
  "command": "get pods -n default"
}

get-contexts

{}

current-context

{}

set-context
