Observability MCP servers

Grafana MCP covers several observability surfaces and Grafana resources; Prometheus MCP focuses on PromQL queries and metric discovery.

These servers have different jobs and permission boundaries. Each summary comes from the publisher’s documentation.

Upstream MCP servers for querying metrics and working with observability data.

Compare the options

2 servers

Best suited to: Observability workflows that need to query metrics and logs and inspect dashboards, alerts, incidents, or related Grafana resources.
Access consideration: The server uses Grafana credentials, and each operation requires the corresponding Grafana RBAC permission and scope.

Best suited to: Focused metric investigation against a Prometheus server, including instant or range queries and target inspection.
Access consideration: The server needs a reachable Prometheus URL and may require basic authentication, a bearer token, or client certificates.

Query supported data sources and search or inspect dashboards.
Expose alerting, incident, and other tool groups; SQL, CloudWatch, InfluxDB, and panel queries are disabled by default.

The server uses Grafana credentials, and each operation requires the corresponding Grafana RBAC permission and scope.
Some tools can create or update Grafana resources; grant least-privilege permissions and enable only needed tool groups.

Prometheus MCP Server exposes PromQL queries and metric discovery through MCP tools.
