✨ Features <a id="features"></a>

A powerful and flexible Kubernetes Model Context Protocol (MCP) server implementation with support for Kubernetes and OpenShift.

✅ Configuration:
- Automatically detect changes in the Kubernetes configuration and update the MCP server.
- View and manage the current Kubernetes .kube/config or in-cluster configuration.
✅ Generic Kubernetes Resources: Perform operations on any Kubernetes or OpenShift resource.
- Any CRUD operation (Create or Update, Get, List, Delete).
✅ Pods: Perform Pod-specific operations.
- List pods in all namespaces or in a specific namespace.
- Get a pod by name from the specified namespace.
- Delete a pod by name from the specified namespace.
- Show logs for a pod by name from the specified namespace.
- Exec into a pod and run a command.
- Run a container image in a pod and optionally expose it.
✅ Namespaces: List Kubernetes Namespaces.
✅ Events: View Kubernetes events in all namespaces or in a specific namespace.
✅ Projects: List OpenShift Projects.

Unlike other Kubernetes MCP server implementations, this IS NOT just a wrapper around kubectl or helm command-line tools.

There is NO NEED for external dependencies or tools to be installed on the system. If you're using the native binaries you don't even need to have Node or Python installed on your system.

🚀 Getting Started <a id="getting-started"></a>

Requirements

Access to a Kubernetes cluster.

Claude Desktop

Using npx

If you have npm installed, this is the fastest way to get started with kubernetes-mcp-server on Claude Desktop.

Open your claude_desktop_config.json and add the mcp server to the list of mcpServers:

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

VS Code / VS Code Insiders

Install the Kubernetes MCP server extension in VS Code Insiders by pressing the following link:

Alternatively, you can install the extension manually by running the following command:

# For VS Code
code --add-mcp '{"name":"kubernetes","command":"npx","args":["kubernetes-mcp-server@latest"]}'
# For VS Code Insiders
code-insiders --add-mcp '{"name":"kubernetes","command":"npx","args":["kubernetes-mcp-server@latest"]}'

Goose CLI

Goose CLI is the easiest (and cheapest) way to get rolling with artificial intelligence (AI) agents.

Using npm

If you have npm installed, this is the fastest way to get started with kubernetes-mcp-server.

Open your goose config.yaml and add the mcp server to the list of mcpServers:

extensions:
  kubernetes:
    command: npx
    args:
      - -y
      - kubernetes-mcp-server@latest

Vibe Coding a simple game and deploying it to OpenShift

In this demo, I walk you through the process of Vibe Coding a simple game using VS Code and how to leverage Podman MCP server and Kubernetes MCP server to deploy it to OpenShift.

⚙️ Configuration <a id="configuration"></a>

The Kubernetes MCP server can be configured using command line (CLI) arguments.

You can run the CLI executable either by using npx or by downloading the latest release binary.

# Run the Kubernetes MCP server using npx (in case you have npm installed)
npx kubernetes-mcp-server@latest --help

# Run the Kubernetes MCP server using the latest release binary
./kubernetes-mcp-server --help

Configuration Options

| Option | Description | |---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | --sse-port | Starts the MCP server in Server-Sent Event (SSE) mode and listens on the specified port. | | --log-level | Sets the logging level (values from 0-9). Similar to kubectl logging levels. |
