🎯 Overview

This project integrates two powerful technologies to create a seamless Kubernetes management experience:

1. MCP Server for Kubernetes - AI-powered command interface for Kubernetes operations
2. Rancher UI Extensions - Visual interface extensions for Rancher management platform

The combination provides both command-line AI assistance and visual management capabilities through a unified interface.

🔄 System Workflow

Architecture Overview

The K8s AI Assistant follows a multi-layered architecture that processes natural language queries through AI analysis and executes Kubernetes operations via MCP protocols.

Core Components

Component	Technology	Protocol	Port	Purpose
Frontend	Vue.js + Rancher Shell	HTTP/HTTPS	8005	User interface and chat experience
Backend API	Express.js	HTTP	8055	Request routing and response formatting
AI Model	Ollama (gpt-oss:20b)	OpenAI-compatible API	11434	Natural language processing and intent mapping
MCP Server	Node.js + TypeScript	JSON-RPC + SSE	3000	Kubernetes command execution
Kubernetes	kubectl + Helm	Kubernetes API	6443	Cluster management and resource operations

Request Flow

1. User submits natural language query via Rancher UI extension
2. Backend API validates and routes request to AI model
3. Ollama AI analyzes intent and maps to Kubernetes operations
4. MCP Server executes kubectl/Helm commands via JSON-RPC
5. Kubernetes API returns cluster data and operation results
6. Response chain processes data through AI formatting
7. Frontend displays formatted results (tables, logs, insights)

Key Features

• Natural Language Processing: Converts user queries to Kubernetes commands
• Real-time Execution: Live cluster data retrieval and operation execution
• Intelligent Formatting: AI-powered response formatting and insights
• Secure Operations: RBAC-compliant cluster access and audit logging
• Extensible Architecture: Modular design for easy feature additions
