+# flowagent (Power Automate MCP, via mcpo service) — Secrets Reference
+# Source: mcpo/flowagent — built into a custom image, consumed by the
+# "mcpo" service in ai.yaml (NEVER mcpo-critical).
+#
+# Add SECRET values to Woodpecker at:
+#   https://woodpecker.bryanmail.net
+#   homelab/compose-files → Settings → Secrets
+#
+# Prerequisite (manual, outside GitOps — Azure Portal):
+#   1. Entra ID → App registrations → New registration
+#      Name: flowagent-mcp-homelab, single tenant
+#   2. API permissions → add Power Automate / Flow Service application
+#      permissions + Dynamics CRM user_impersonation (Dataverse access)
+#   3. Grant admin consent
+#   4. Certificates & secrets → new client secret → copy value immediately
+#   5. Power Platform Admin Center → target environment → S2S apps →
+#      register the application user for this app ID (required for
+#      Dataverse/environment access by a service principal)
+#
+# NOTE: the OLD "powerautomate" mcpo/config.json entry (npm package
+# powerautomate-mcp, client_id 84b431ed-..., tenant_id 0f6cf991-...) was
+# never onboarded to this secrets pipeline and is being replaced by this.
+# Do not reuse those IDs unless you've independently confirmed in Azure
+# Portal that the old App Registration still exists, still has valid
+# permissions/consent, and you intend to reuse it — otherwise register new.
