Kubernetes Troubleshooting

Expert debugging and diagnostics for Kubernetes clusters using kubectl-mcp-server tools.

Requires the cilium, diagnostics, istio, policy, security toolsets: start kubectl-mcp-server with --toolsets default,cilium,diagnostics,istio,policy,security (or MCP_TOOLSETS=default,cilium,diagnostics,istio,policy,security). For deep work, the project-maintained MCP servers may fit better: Kyverno: https://github.com/nirmata/kyverno-mcp.

• Node issues: NotReady, MemoryPressure, DiskPressure, NetworkUnavailable, PIDPressure
• Keywords: "logs", "events", "describe", "why isn't working", "stuck", "not responding"
