MCP Kubernetes Server MCP Server

mcp-kubernetes-server

The mcp-kubernetes-server is a server implementing the Model Context Protocol (MCP) to enable AI assistants (such as Claude, Cursor, and GitHub Copilot) to interact with Kubernetes clusters. It acts as a bridge, translating natural language requests from these assistants into Kubernetes operations and returning the results.

It allows AI assistants to:

• Query Kubernetes resources
• Execute kubectl commands
• Manage Kubernetes clusters through natural language interactions
• Diagnose and interpret the states of Kubernetes resources

How It Works

The mcp-kubernetes-server acts as an intermediary between AI assistants (that support the Model Context Protocol) and your Kubernetes cluster. It receives natural language requests from these assistants, translates them into kubectl commands or direct Kubernetes API calls, and executes them against the target cluster. The server then processes the results and returns a structured response, enabling seamless interaction with your Kubernetes environment via the AI assistant.

How To Install

Prerequisites

Before installing mcp-kubernetes-server, ensure you have the following:

• A working Kubernetes cluster.
• A kubeconfig file correctly configured to access your Kubernetes cluster (the server requires this file for interaction).
• The kubectl command-line tool installed and in your system's PATH (used by the server to execute many Kubernetes commands).
• The helm command-line tool installed and in your system's PATH (used by the server for Helm chart operations).
• Python >= 3.11, if you plan to install and run the server directly using uvx (without Docker).

Docker

Get your kubeconfig file for your Kubernetes cluster and setup in the mcpServers (replace src path with your kubeconfig path):

{
  "mcpServers": {
    "kubernetes": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "--mount", "type=bind,src=/home/username/.kube/config,dst=/home/mcp/.kube/config",
        "ghcr.io/feiskyer/mcp-kubernetes-server"
      ]
    }
  }
}

UVX

To run the server using uvx (a tool included with uv, the Python packager), first ensure uv is installed:

# For Linux and MacOS
curl -LsSf https://astral.sh/uv/install.sh | sh

# For Linux
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

# For MacOS
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/arm64/kubectl"

curl -sSL https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

Config your MCP servers in Claude Desktop, Cursor, ChatGPT Copilot, Github Copilot and other supported AI clients, e.g.

{
  "mcpServers": {
    "kubernetes": {
      "command": "uvx",
      "args": [
        "mcp-kubernetes-server"
      ],
      "env": {
        "KUBECONFIG": "<your-kubeconfig-path>"
      }
    }
  }
}
