From bdf958af0a589e74d140feee98532a16e3a446be Mon Sep 17 00:00:00 2001 From: Ambient Code Bot Date: Wed, 20 May 2026 14:13:06 -0400 Subject: [PATCH] Remove ROSA cluster discovery from fetch_pricing.py The kubeconfig scan (oc get nodes across all contexts) provided no value and touched clusters unnecessarily. Remove the rosa_cluster_instance table, v_rosa_estimated_cost view, rosa_cluster_costs MCP tool, and --rosa-only/--skip-rosa CLI flags. ROSA service fee pricing (static published rates) is retained in cloud_pricing since it requires no cluster access.
