Browse With Inspector

To use latest published version with Inspector you can run this:

npx @modelcontextprotocol/inspector npx @strowk/mcp-k8s

, or to use version built from sources, then in root folder of this project:

Use With Claude

<details><summary><b> Demo Usage </b></summary>

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:

</details>

To use this MCP server with Claude Desktop you would firstly need to install it.

You have several options for installation:

	<a href="#using-smithery">Smithery</a>	<a href="#using-mcp-get">mcp-get</a>	<a href="#prebuilt-from-npm">Pre-built NPM</a>	<a href="#from-github-releases">Pre-built in Github</a>	<a href="#building-from-source">From sources</a>
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)
