-The SonarQube MCP Server provides comprehensive monitoring and observability features for production deployments, including Prometheus metrics, OpenTelemetry tracing, health checks, and circuit breakers.
+The SonarQube MCP Server provides monitoring features through logging and error tracking. When deployed via MCP gateways, monitoring is typically handled at the gateway level.
