Use With Claude

Following chat with Claude Desktop demonstrates how it looks when selected particular context as a resource and then asked to check pod logs for errors in kube-system namespace:

To use this MCP server with Claude Desktop (or any other client) you might need to choose which way of installation to use.

You have multiple options:

	Smithery	mcp-get	Pre-built NPM	Pre-built in Github	From sources	Using Docker
Claude Setup	Auto	Auto	Manual	Manual	Manual	Manual
Prerequisite	Node.js	Node.js	Node.js	None	Golang	Docker

Using Smithery

To install MCP K8S Go for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @strowk/mcp-k8s --client claude

Using mcp-get

To install MCP K8S Go for Claude Desktop automatically via mcp-get:

npx @michaellatman/mcp-get@latest install @strowk/mcp-k8s

Manually with prebuilt binaries

Prebuilt from npm

Use this if you have npm installed and want to use pre-built binaries:

npm install -g @strowk/mcp-k8s

Then check version by running mcp-k8s --version and if this printed installed version, you can proceed to add configuration to claude_desktop_config.json file:

{
  "mcpServers": {
    "mcp_k8s": {
      "command": "mcp-k8s",
      "args": []
    }
  }
}

, or using npx with any client:

npx @strowk/mcp-k8s

For example for Claude:

{
  "mcpServers": {
    "mcp_k8s": {
      "command": "npx",
      "args": [
        "@strowk/mcp-k8s"
      ]
    }
  }
}

From GitHub releases

Head to GitHub releases and download the latest release for your platform.

Unpack the archive, which would contain binary named mcp-k8s-go, put that binary somewhere in your PATH and then add the following configuration to the claude_desktop_config.json file:

{
  "mcpServers": {
    "mcp_k8s": {
      "command": "mcp-k8s-go",
      "args": []
    }
  }
}

Building from source

You would need Golang installed to build this project:

go get github.com/strowk/mcp-k8s-go
go install github.com/strowk/mcp-k8s-go

, and then add the following configuration to the claude_desktop_config.json file:

{
  "mcpServers": {
    "mcp_k8s_go": {
      "command": "mcp-k8s-go",
      "args": []
    }
  }
}

Using Docker

This server is built and published to Docker Hub since 0.3.1-beta.2 release with multi-arch images available for linux/amd64 and linux/arm64 architectures.

You can use latest tag f.e like this:

docker run -i -v ~/.kube/config:/home/nonroot/.kube/config --rm mcpk8s/server:latest

Windows users might need to replace ~/.kube/config with //c/Users/<username>/.kube/config at least in Git Bash.

For Claude:

{
  "mcpServers": {
    "mcp_k8s_go": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "-v",
        "~/.kube/config:/home/nonroot/.kube/config",
        "--rm",
        "mcpk8s/server:latest"
      ]
    }
  }
}

Environment Variables and Command-line Options

The following environment variables are used by the MCP server:

• KUBECONFIG: Path to your Kubernetes configuration file (optional, defaults to ~/.kube/config)

The following command-line options are supported:

• --allowed-contexts=<ctx1,ctx2,...>: Comma-separated list of allowed Kubernetes contexts that users can access. If not specified, all contexts are allowed.
• --readonly: Disables any tool which can write changes to the cluster
• --help: Display help information
• --version: Display version information

For example if you are configuring Claude Desktop, you can add the following configuration to claude_desktop_config.json file:

{
    "mcpServers": {
        "mcp_k8s": {
            "command": "mcp-k8s",
            "args": [
                "--allowed-contexts=dev,prod",
                "--readonly"
            ]
        }
    }
}

, which would allow only dev and prod contexts to be used and would disable any tool which can write changes to the cluster.
