Overview

What is Mcp Kubernetes Ro?

Mcp Kubernetes Ro is a read-only Model Context Protocol (MCP) server that provides AI assistants with safe, read-only access to Kubernetes clusters. It uses your local kubectl configuration to enable comprehensive cluster inspection and troubleshooting without requiring kubectl to be installed.

How to use Mcp Kubernetes Ro?

Install via pre-built binaries, Homebrew, or Docker. Configure it in your MCP client (e.g., editor settings) with the command mcp-kubernetes-ro and optional flags like --kubeconfig, --namespace, or --transport. It reads your default kubeconfig (~/.kube/config) and environment variable KUBECONFIG. Run in stdio mode by default, or use --transport=sse --port=8080 for HTTP SSE mode.

Encode and decode base64 data for secrets
Supports stdio and SSE transport modes
Does not require kubectl binary installed

Use cases of Mcp Kubernetes Ro

AI assistant inspects cluster resources without risk of modification
Developer troubleshoots pods by retrieving filtered logs
Security auditor decodes base64 secrets for review
Operations engineer lists API resources across multiple contexts
Metrics monitoring when metrics-server is installed in the cluster

FAQ from Mcp Kubernetes Ro

Does Mcp Kubernetes Ro require kubectl to be installed?

No. It uses your local kubectl configuration (kubeconfig) but does not depend on the kubectl binary.

Can Mcp Kubernetes Ro modify cluster resources?

No. The server provides read‑only access and prevents any destructive operations.

What transport modes are supported?

The server supports both stdio (default) and Server‑Sent Events (SSE) transport modes.

How do I specify a different kubeconfig file?

Use the --kubeconfig command‑line flag or set the KUBECONFIG environment variable.

Are node/pod metrics always available?

Metrics tools (get_node_metrics, get_pod_metrics) require the metrics‑server to be installed in the cluster; otherwise, they return an error.
