Worked on the grafana/helm-charts repository to deliver a targeted feature that conditionally configures the GRAFANA_SERVICE_ACCOUNT_TOKEN environment variable during Grafana MCP deployments. This approach ensures the token is set only when an API key or API key secret name is provided, reducing unnecessary token exposure and deployment failures. Leveraging Helm, Kubernetes, and YAML, the implementation aligns with best practices for environment-driven configuration and Helm chart design. The change improves deployment robustness and flexibility, making it easier for teams to onboard and manage optional API key scenarios without manual intervention or risk of misconfiguration, while maintaining clarity in deployment behavior.
