runspec-grafana

A Grafana runnable for runspec, ported from the read tools of the Grafana MCP server onto the Grafana HTTP API — not proxying that server. One runnable — grafana — with a verb per tool. pip install it into a venv and it's discoverable by runspec local, runspec serve (MCP), and runspec-console.

runspec serve flattens each verb into a leaf MCP tool (grafana_search-dashboards, grafana_query-prometheus, …).

Install

pip install runspec-grafana

Verbs

All autonomous (read-only) except create-annotation, which is confirm.

PromQL and LogQL run through Grafana's datasource proxy, so only the Grafana token is needed — never the datasource's own credentials. --datasource takes a UID or a name; without it the default (or only) Prometheus or Loki datasource is used.

Output

Results are compact by default, because an agent re-reads every tool result on each later step:

• get-dashboard returns a summary: folder, tags, variables, and one row per panel. --include queries adds each panel's query text, --panel <id> keeps one panel, --raw returns the full dashboard JSON.
• query-prometheus --query-type range summarises each series (points, first, last, min, max); --include-values returns every sample.
• query-loki-logs lists each stream's labels once and gives the lines newest first, each cut to --max-line-chars (500).
• list-alert-rules puts firing rules first with counts by state; --include alerts adds the active alert instances.
• Every list takes --limit and says truncated: true when it cut something.

A person at a terminal gets readable text; agents, pipes, the console's Forms tab and schedulers get JSON.

Times accept Unix seconds or milliseconds, RFC 3339, now-1h, or a duration back from now (5m, 1h30m).

Auth — env vars

export GRAFANA_URL=https://grafana.example.com            # default http://127.0.0.1:3000
export GRAFANA_SERVICE_ACCOUNT_TOKEN=glsa_...             # or GRAFANA_TOKEN, or:
export GRAFANA_USERNAME=<user> GRAFANA_PASSWORD=<password>
export GRAFANA_ORG_ID=2                                   # X-Grafana-Org-Id
export GRAFANA_CA_BUNDLE=/etc/pki/internal-ca.pem         # private CA

Use a service account token. The Viewer role covers every read except list-dashboard-versions; that and create-annotation need Editor.

--env <label> reads GRAFANA_<LABEL>_* first (--env prod-eu → GRAFANA_PROD_EU_URL). --url, --org-id and --grafana-token override the environment; the token arg is a password type, so it comes through the runspec-console secret channel and never on a command line. A runspec-console credential labelled Grafana of the token kind supplies GRAFANA_TOKEN, and one of the username + password kind supplies GRAFANA_USERNAME/PASSWORD, with no extra configuration.

Building your own runnables

The logic lives in runspec-grafana-core, which has no runspec dependency and surfaces no runnables. A private package can depend on it alone, build a GrafanaConfig in code, and wrap the helpers as narrower runnables — for example a checkout-errors runnable that runs one fixed LogQL query for a team:

from runspec_grafana_core import config_from_env, query_loki_logs

cfg = config_from_env("prod")
errors = query_loki_logs(cfg, '{app="checkout"} |= "level=error"', start="30m", limit=20)
