Radar

Radar is an open-source Kubernetes UI with a built-in Model Context Protocol server for AI agents.

Radar is an open-source interface for managing and troubleshooting Kubernetes clusters. It features a human-optimized UI and an MCP server for AI agents to diagnose issues, view topology, and trace events. Users can run it locally with a kubeconfig file or in-cluster via Helm. It supports ArgoCD and Flux for GitOps visibility, Helm releases, image internals, and audit checks. Radar Cloud adds fleet-wide alerts, AI root cause investigations, and shared views for teams. It is built for operators managing multi-cluster environments across regions.
