Overview

What is Kubernetes MCP Server?

Kubernetes MCP Server (Kai) is a Model Context Protocol server that exposes Kubernetes operations as MCP tools, letting LLM clients like Claude Desktop, Cursor, and Continue manage clusters through natural language.

How to use Kubernetes MCP Server?

Install via go install github.com/basebandit/kai/cmd/kai@latest or use the Docker image cyclon/kai:v1.0.0. By default it uses your current kubectl context. Configure with Claude Desktop, Cursor, or Continue by adding the server path to their MCP settings. Run with flags like -kubeconfig, -transport, -in-cluster, or -tls-cert to customize behavior.

FAQ from Kubernetes MCP Server

How does the server connect to a Kubernetes cluster?

It uses your current kubectl context by default. You can specify a custom kubeconfig with -kubeconfig and a context with -context.

What transports are supported?

stdio (default), streamable-http, and sse-legacy (deprecated). For remote use, run with -transport=streamable-http and -sse-addr=:8080.

How can I run the server inside a Kubernetes cluster?

Use the -in-cluster flag so it uses the pod's service account credentials. The recommended way is to deploy via kmcp with an MCPServer resource.

How do I configure it with Claude Desktop?

Add the server command (and optional args) to your claude_desktop_config.json under mcpServers, for example: "command": "/path/to/kai".

Can I secure the HTTP transport with TLS?

Yes, supply the -tls-cert and -tls-key options pointing to your certificate and private key files to enable HTTPS.
