An MCP (Model Context Protocol) server application for Kubernetes operations, providing a standardized API to interact with multiple Kubernetes
Connect Multi Cluster Kubernetes to Claude, Cursor or any other MCP client and it stops being a tab you switch to. An MCP (Model Context Protocol) server application for Kubernetes operations, providing a standardized API to interact with multiple Kubernetes clusters simultaneously using multiple kubeconfig files. The multi cluster kubernetes mcp server is what makes that connection.
An MCP (Model Context Protocol) server for managing multiple Kubernetes clusters simultaneously. Provides 60+ tools covering cluster operations, resource management, monitoring, RBAC, storage, networking, and more -- all accessible through AI assistants like Claude Desktop.
@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
k8s_get_contexts — List all available contexts across all kubeconfig filesk8s_get_namespaces — List all namespaces in a clusterk8s_create_ns — Create a new namespace with optional labels/annotationsk8s_delete_ns — Delete a namespace (protects system namespaces)k8s_get_nodes — List all nodes with status, roles, capacity, and versionk8s_cluster_info — Comprehensive cluster health summary (nodes, pods, deployments, warnings)k8s_get_resources — List resources of any kind (pods, deployments, services, ingress, etc.)k8s_get_resource — Get the complete definition of a single resourcek8s_get_pod_logs — Get pod logs with duration filtering and container selectionk8s_get_events — List cluster events in a namespace, sorted by most recentk8s_describe — Detailed resource description similar to kubectl describek8s_apis — List all available API groups and resources in the clusterConfiguration is passed through the environment: KUBECONFIG_DIR. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
metrics-server installed in clusters for k8s_top_* and k8s_cluster_info toolsAmong the cloud and infrastructure options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Multi Cluster Kubernetes's toolset — k8s_get_contexts, k8s_get_namespaces, k8s_create_ns and 11 more — is a fair guide to whether it matches your workflow. It is maintained by razvanmacovei; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
