Grafana

Grafana (via gcx CLI)

Operate Grafana with gcx, the official CLI: dashboards, datasources, alerts, metrics/logs/traces. It replaces a Grafana MCP server.

Do NOT use raw curl against the Grafana HTTP API, and do NOT use grafana-backup-tool / grizzly. Those are pre-skill fallbacks. gcx gives you structured output, pagination, error handling, and token-efficient output, and its commands evolve with the Grafana version.

Environment assumption: this skill targets self-hosted (OSS / Enterprise). Auth uses a service account token + org-id. Grafana Cloud-only features (SLO, Synthetic Monitoring, IRM, k6) do not apply — when asked for those, say so and propose a self-hosted-viable alternative.

🔑 Core: discover before you act (the key to replacing MCP)

gcx has many commands and they evolve, so never memorize or guess commands. Discover them with progressive disclosure to save tokens:

gcx help-tree --depth 1 -o text   # Step 1: list all top-level groups (~30 lines)
gcx help-tree <group> -o text     # Step 2: expand one group's subtree
gcx <group> <subcommand> --help   # Step 3: see exact flags and args

When unsure of syntax, run those three steps. Do not web-search grafana.com docs, and do not guess API paths.

Prerequisite check

gcx --version

If missing, download a pre-built binary from the GitHub releases (no Go toolchain needed) — see references/setup.md for details:

ver=$(curl -fsSL https://api.github.com/repos/grafana/gcx/releases/latest \
  | sed -n 's/.*"tag_name": *"v\{0,1\}\([^"]*\)".*/\1/p')
os=$(uname -s | tr '[:upper:]' '[:lower:]')
arch=$(uname -m); [ "$arch" = "x86_64" ] && arch=amd64; [ "$arch" = "aarch64" ] && arch=arm64
curl -fsSL "https://github.com/grafana/gcx/releases/download/v${ver}/gcx_${ver}_${os}_${arch}.tar.gz" \
  | sudo tar -xz -C /usr/local/bin gcx

Intent-to-group quick reference (self-hosted groups)

When you already know the user's intent, go straight to the right group and skip discovery:

If no command exists for the request, say so and propose the nearest viable flow. Don't use gcx api when a dedicated command exists.

Verify context before acting

gcx config check            # validate the active context and test connectivity
gcx config current-context  # show the active context name
gcx config use-context <name>
gcx <any-command> --context <name>   # target one context without switching

First-time setup (install, self-hosted auth, multi-context, troubleshooting): see references/setup.md.

Output control

Default to -o json for programmatic work. Prefer gcx's built-in --json field selection over piping to jq/python — gcx itself hints "no external parsing needed". Discover fields with --json list, then select with --json a,b.

Parsing pitfall: with -o json the JSON goes to stdout, but a line {"class":"hint",...} goes to stderr. When parsing externally, do not use 2>&1 | jq (it merges the hint and breaks parsing) — read stdout directly (use 2>/dev/null if needed).

Safe mutation workflow

For any write operation, follow this order (skip steps only when the user explicitly asks for speed):

1. Verify context — confirm which environment you're operating on
2. Read current state — list / get the resource first
3. Build payload from a template — gcx resources schemas <kind> / gcx resources examples <kind>, don't hand-craft it
4. Preview — run --dry-run where available
5. Apply — create / update / delete
6. Verify — get the resource again to confirm the change landed

Parallelism

gcx commands are stateless API calls. Issue multiple queries with no output dependency as parallel Bash calls in a single message (list/get across resources, multiple schema/example fetches, independent queries). Only serialize when a later call needs an earlier call's output.

Secret safety

Never read the config file directly (it contains a plaintext token). Use gcx config view (it redacts secrets) to inspect. When passing a token to an external tool, use a shell variable, not an inline value.
