# This example shows how to integrate an in-cluster kubernetes-mcp-server
# (deployed via MCP Lifecycle Operator) with the mcp-gateway.
#
# Prerequisites:
# 1. mcp-gateway deployed in the cluster (in gateway-system namespace)
# 2. kubernetes-mcp-server deployed via mcpserver-with-rbac.yaml
#
# This creates:
# - HTTPRoute: Routes traffic from mcp-gateway to the kubernetes-mcp-server Service
#   * IMPORTANT: Must include a hostname (e.g., kubernetes-mcp.mcp.local)
# - MCPServerRegistration: Registers the MCP server with the gateway
#
# Note: Unlike external MCP servers, you do NOT need:
# - ExternalName Service (you already have a ClusterIP Service from the MCPServer CR)
# - ServiceEntry (not needed for in-cluster services)
#
# After applying, verify the registration:
# $ kubectl get mcpserverregistration kubernetes-mcp-server -n default
# NAME                    PREFIX   TARGET           PATH   READY   TOOLS
# kubernetes-mcp-server   kube_    kubernetes-mcp   /mcp   True    13
