mcp-grafana

In-cluster MCP server for read-only Grafana, Prometheus, Alertmanager, and Loki diagnostics.

Tools

  • get_grafana_health() - Grafana health/status.

  • list_datasources() - compact datasource inventory.

  • query_prometheus() - instant PromQL through Grafana's Prometheus datasource proxy.

  • query_prometheus_range() - range PromQL through Grafana's Prometheus datasource proxy.

  • list_prometheus_alerts() - Prometheus alert state from the datasource proxy.

  • list_alertmanager_alerts() - Alertmanager alerts from the datasource proxy.

  • query_loki() - Loki range query through the Grafana datasource proxy.

query_prometheus, list_prometheus_alerts, and list_alertmanager_alerts default to the prometheus and alertmanager datasource UIDs provisioned by kube-prometheus-stack. query_loki defaults to the loki UID pinned in romaine-life/osms.

Auth

Inbound transport is gated by kube-rbac-proxy using Kubernetes TokenReview/SubjectAccessReview, matching the other romaine.life MCP servers.

Outbound calls to Grafana use the calling session pod's auth.romaine.life service-principal JWT, forwarded by the pod's mcp-auth-proxy sidecar in the X-Auth-Romaine-Token header. Grafana validates that JWT via its [auth.jwt] configuration, so this server does not mint or store a separate Grafana service account token.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
