general MCP Server
The missing open-source Kubernetes UI with a built-in MCP server for AI agents. See what's broken, why, and what changed. Issues, Topology, event timeline, Helm, GitOps, live service traffic, and cluster audits - all in one Go binary.

Default
Server port
Timeline storage backend: `memory`, `sqlite`, or `postgres`
Maximum events to retain in timeline (memory only)
Action
Toggle dark/light theme
Fit topology to screen
Open YAML view
Open logs (pods/workloads)
Close panel/modal/search
Maximum SQLite DB + WAL size before pruning oldest events (e.g. `800Mi`, `8Gi`; `0` disables)
Maximum time a kubeconfig context switch may take. Widen on high-latency control planes — see [Tuning for slow clusters](#tuning-for-slow-or-high-latency-clusters). Env: `RADAR_CONTEXT_SWITCH_TIMEOUT`.
Cap on the namespace-fallback probe fanout (used by accounts that can list namespaces cluster-wide but not list a specific kind cluster-wide). Raise above `20` for clusters with more than 20 namespaces. Env: `RADAR_MAX_SCOPE_CANDIDATES`.
Start only the MCP catalog over stdio for registry introspection
Hard upper bound on the initial critical-cache sync wait before Radar falls through to a partial-data render. Env: `RADAR_FIRST_PAINT_BACKSTOP`.
Timeout for the cluster-wide namespace LIST used to decide if the user is RBAC-namespace-restricted. A timeout on a slow control plane is misreported in the UI as "Limited list — RBAC". Env: `RADAR_NAMESPACE_LIST_TIMEOUT`.
Authentication mode: `none`, `proxy`, or `oidc` ([details](docs/authentication.md))

Detect and prevent privilege escalation in Kubernetes pods by monitoring security contexts, capabilities, and syscall patterns with Falco and OPA policies.
Detect container escape attempts in real-time using Falco runtime security rules that monitor syscalls, file access, and privilege escalation.
Implement Kubernetes network segmentation using Calico NetworkPolicy and GlobalNetworkPolicy for zero-trust pod-to-pod communication.
Reduce container attack surface by building application images on Google distroless base images that contain only the application runtime with no shell, package manager, or unnecessary OS utilities.
