About Kubernetes MCP Server

What is Kubernetes MCP Server: Natural Queries, Instant Cluster Insights?

Kubernetes MCP Server is an AI-powered control plane designed to simplify Kubernetes cluster management through natural language interactions. Built with Spring Boot 3.3.6 and Kotlin 1.9.25, it combines real-time diagnostics, intelligent resource management, and secure operations into a developer-friendly package. Think of it as a smart assistant for your cluster that translates human-readable questions into actionable insights without needing complex kubectl commands.

How to use Kubernetes MCP Server: Natural Queries, Instant Cluster Insights?

The workflow is straightforward:
1. Query naturally: Ask questions like "Which namespace is overusing CPU?" or "Why is this pod failing?"
2. Immediate analysis: The server instantly evaluates cluster state using AI-driven diagnostics
3. Actionable insights: Receive prioritized recommendations with troubleshooting steps
Integration requires setting up the server as a control-plane component, configuring namespace permissions, and connecting to your cluster's API server.

Kubernetes MCP Server Features

Key Features of Kubernetes MCP Server: Natural Queries, Instant Cluster Insights?

  • Smart Failure Analysis: Automatically detects common pod failures (dependency issues, resource limits, config errors) and provides mitigation steps
  • Resource Bottleneck Detection: Identifies CPU/memory constraints across namespaces with real-time visualization
  • Secure Execution: Built-in command validation prevents risky pod exec operations while maintaining audit trails
  • Helm Value Validation: Checks chart compatibility and value schemas before deployment
  • Contextual Help: Provides tailored suggestions based on current cluster health metrics

Use Cases of Kubernetes MCP Server: Natural Queries, Instant Cluster Insights?

Common scenarios include:
• Diagnosing sudden performance degradation with "Why is latency spiking in the production namespace?"
• Troubleshooting deployments with "What's blocking this pod's startup?"
• Optimizing resource allocation via "Which workloads can be scaled down safely?"
• Maintaining security posture through automated command sanitization during troubleshooting

Note: MCP tool always uses the kubeconfig file from ~/.kube/config, so make sure it is properly configured.

🏗️ Building the Project

./gradlew clean build

🤝 Integration with Claude Desktop

  1. Install Claude Desktop

  2. Configure the MCP server connection:

    {
    "mcpServers": {
    "spring-ai-mcp-k8s": {
    "command": "java",
    "args": [
    "-Dspring.ai.mcp.server.stdio=true",
    "-Dspring.main.web-application-type=none",
    "-Dlogging.pattern.console=",
    "-jar",
    "<>"
    ]
    }
    }
    }

Note: Make sure to pick the fat jar with all the dependencies

Integration with Other MCP Hosts

The server follows the standard MCP protocol and can be integrated with any MCP host that supports Spring-based MCP servers. Configure your host to point to the server's URL.

🗣️ Natural Language Interactions

💡 Just ask questions naturally - no need to memorize commands!

This AI-powered MCP server understands natural language queries about your Kubernetes cluster. Here are examples of questions you can ask:

🏥 Cluster Health and Diagnostics

📊 What's the overall health of my cluster?
🔍 Are there any resource bottlenecks in the 'production' namespace?
🚨 Show me problematic pods in the 'dev' namespace with recommendations
📅 What events happened in the cluster in the last hour?

📱 Application Management

📋 List all pods in the 'default' namespace and their status
❓ Why is the 'auth-service' pod failing to start?
📝 Show me the logs from the 'payment-processor' pod with error highlighting
📈 What's using the most resources in the 'monitoring' namespace?

⎈ Helm Release Management

📦 What Helm releases are installed in the 'staging' namespace?
⚡ Install the 'prometheus' chart from the official repository
⚙️ What values are configured for the 'elasticsearch' release?
🔄 Update the 'kafka' release to version 2.0.0

Note: I have noticed sometimes LLM will try and generate kubectl commands on the fly, since we would like to stick with the existing MCP tools you can suffix the prompt with "use existing MCP tools, dont generate kubectl commands"
