MCP K8S Go

This project is intended as a both MCP server connecting to Kubernetes and a library to build more servers for any custom resources in Kubernetes.

Currently available:

• resource: K8S contexts as read from kubeconfig configurations
• tool: list-k8s-contexts
• tool: list-k8s-pods in a given context and namespace
• tool: list-k8s-events in a given context and namespace
• tool: list-k8s-services in a given context and namespace
• tool: get-k8s-pod-logs in a given context and namespace

Example usage with Inspector

To use this MCP server with Inspector you can run it from root folder of this project:

tools/inspector/run.sh

Example usage with Claude Desktop

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

You have two options at the moment - use pre-built binaries published in npm or build it from source, in which case names of binaries might differ.

Using pre-built binaries

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

Demo usage with Claude Desktop

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:
