Horizontal autoscaling will only activate when vertical autoscaling is disabled (i.e., the service is set to a fixed size). The same applies to vertical autoscaling being enabled when the number of replicas is fixed. This behavior will become more flexible in future releases. ### ClickStack MCP Server (open source) {#clickstack-mcp-server}
