Use With Claude

Demo Usage

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 you would firstly need to install it.

You have several options for installation:

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

Using Smithery

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

npx @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": []
        }
    }
}

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 from Claude Desktop

Now you should be able to run Claude Desktop and:

• see K8S contexts available to attach to conversation as a resource
• ask Claude to list contexts
• ask Claude to list pods in a given context and namespace
• ask Claude to list events in a given context and namespace
• ask Claude to read logs of a given pod in a given context and namespace

Environment Variables

The following environment variables are used by the MCP server:

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