K8s MCP

K8s MCP

A Kubernetes assistant powered by Model Context Protocol (MCP) and Google Gemini.

Requirements

• Python 3.10+
• Kubernetes cluster with kubeconfig configured
• Node.js 18+ (for frontend)
• Bun (optional, for faster frontend builds)

Quick Start

Use the Makefile to run different components:

1. MCP Server

Starts the MCP server that communicates with your Kubernetes cluster.

make mcp-server

Requires: Active Kubernetes cluster and configured kubeconfig.

2. CLI Mode

Interactive command-line interface to query your Kubernetes cluster.

make cli

3. Web Application (Backend + Frontend)

Start the backend API server:

make backend

Start the frontend in another terminal:

make frontend

Then open http://localhost:5173 in your browser.

4. All at Once

Start all services in background (development mode):

make dev
