📋 Requirements
Node.js v18+
kubectl installed and configured to access your cluster
@modelcontextprotocol/cli (optional, for testing)
🔧 Installation
🏃 Running the Server
The server runs on stdio transport and will output: Kubernetes MCP server running on stdio
🔌 Connecting to MCP Clients
Claude Desktop
Add to your claude_desktop_config.json:
Other MCP Clients
For clients that support MCP, configure them to connect to this server using:
Command:
nodeArgs:
["/path/to/server.js"]Transport: stdio
💡 Example Usage
Once connected to an MCP-compatible client, you can use natural language like:
"List all pods in the default namespace"
"Show me the logs for the nginx pod"
"Port forward the web service on port 8080 to my local port 3000"
"Scale the api deployment to 3 replicas"
"What events happened recently in the kube-system namespace?"
🧪 Testing
Run the test script to verify everything is working:
This will check:
✅ kubectl availability
✅ Server syntax validation
✅ Server startup capability
✅ Cluster connectivity
🛠️ Development
To add new tools:
Add the tool definition to the
toolsarray inserver.jsAdd a corresponding case in the
CallToolRequestSchemahandlerImplement the kubectl command and response formatting
Test with
node test.js
⚠️ Security Notes
This server executes kubectl commands on your system
Ensure your kubectl context is set to the correct cluster
Be cautious when scaling deployments or port-forwarding in production
Review all operations before execution

🤝 Contributing
Contributions are welcome! Please feel free to submit issues and enhancement requests.
Restart your MCP-enabled client (Cursor AI, Claude Desktop, VS Code MCP extension, etc.)
Now you can issue natural commands like:
“Show me all pods in namespace payments”
“Port forward postgres service to local 5432”
“Get logs from api-pod”
