Grafana vs Terraform MCP Server
Comparing Grafana and Terraform as MCP servers? Grafana (query grafana dashboards) is best when incident investigation across metrics + logs. Terraform (query terraform registry) is best when grounding generated hcl in real provider schemas. Both run as Model Context Protocol servers and can coexist in the same client. Updated 2026.
Verdict
These are not competitors, and the useful verdict is to say so plainly. Grafana is an observability MCP: query metrics and logs, search dashboards, inspect alert rules - Prometheus and Loki through one server, on an API key. Terraform is an infrastructure-authoring MCP: look up provider schemas and module inputs so generated HCL is grounded in what really exists, with no auth needed for registry queries.
You reach for them at different moments. Terraform is the build phase - discovering resources, checking module inputs, managing HCP workspaces and runs. Grafana is the operate phase - incident investigation across metrics and logs. A team running infrastructure at any scale usually wants both installed, because the loop between provisioning something and watching it behave is continuous.
Each carries one warning worth reading. Terraform's rules out unattended apply: grounding generated HCL is high-leverage, executing it unsupervised is not. Grafana's needs version 9.0 or later and a service account. Neither is a substitute for the other, so if you are choosing between them you are probably solving the wrong problem - pick by which phase currently hurts more.

FAQ
Do these overlap at all?
Barely. Terraform describes infrastructure before it exists; Grafana observes it after. The only real touchpoint is a change made through one showing up in the other - which is the argument for running both rather than choosing.
Which needs credentials?
Grafana needs an API key and a service account on a 9.0-or-later instance. Terraform needs no auth for registry lookups, which makes it unusually easy to add - credentials only enter for HCP Terraform workspace and run management.
Grafana vs Terraform: which MCP server should I use?
Pick Grafana when incident investigation across metrics + logs. Pick Terraform when grounding generated hcl in real provider schemas. Grafana is built for query grafana dashboards, while Terraform focuses on query terraform registry.
Can I run both Grafana and Terraform together?
Yes. MCP clients run each server as a separate process and surface every server's tools simultaneously, so you can install both and let your agent decide which to call. Be deliberate with auth scopes when stacking servers.
