A setup checker for n8n-autopilot, a command-line toolkit for working with n8n. It verifies the command-line tool, workspace connection, n8n API access, companion plugin, node information, and inventory status.

Use it after installing or upgrading n8n-autopilot, after setup, or when checking whether the n8n workspace and its supporting tools are working.

It identifies missing or outdated setup parts when commands fail or behave unexpectedly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00064	$0.00761
Opus 5	$0.00032	$0.00380
Sonnet 5	$0.00013	$0.00152
Haiku 4.5	$0.00006	$0.00076

Security

Grade B, and why

check-mcps scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 74 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Check n8n-autopilot Setup

n8n-autopilot is CLI-only (npx n8nac …). There is no MCP server entry for this plugin — the mcp__n8n-as-code__* namespace seen in older docs was an upstream assumption that never landed (the npm n8nac mcp entry-point is broken and Etienne's companion plugin ships skill knowledge, not an MCP server).

This skill verifies the actually-required layers.

Step 1 — n8nac CLI reachable

npx n8nac --version 2>&1

Expect 2.2.0 or higher. Anything below is unsupported.

Step 2 — Full health check via setup-check.sh

bash "$CLAUDE_PLUGIN_ROOT/scripts/setup-check.sh" 2>&1

($CLAUDE_PLUGIN_ROOT is set by Claude Code when running plugin commands — no manual path needed.)

Inspect the output. The script checks, in order:

npx available
n8nac CLI version vs minimum/reference
n8nac workspace bound (workspace status --json returns env config)
n8n API reachable (host pulled from the workspace status JSON)
Companion plugin n8n-as-code@n8nac-marketplace enabled (warns if missing — the companion's n8n-architect skill is the primary source of n8n authoring knowledge)
Community-node schema coverage
Inventory freshness (informational)

Step 3 — Companion plugin (`n8n-as-code`) enabled

grep -q '"n8n-as-code@n8nac-marketplace": true' "$HOME/.claude/settings.json" && \
  echo "OK: n8n-as-code companion enabled" || \
  echo "WARN: n8n-as-code companion not enabled — install it for best UX:
  claude plugin marketplace add EtienneLescot/n8n-as-code
  claude plugin install n8n-as-code@n8nac-marketplace"

Step 4 — Project visibility

node "$CLAUDE_PLUGIN_ROOT/skills/find-project/scripts/list.js"

Prints the workspace-pinned project plus every project derivable from credential ownership. Surface the table to the user — multi-project blindness (referencing creds from the wrong project) is the most common cause of "workflow pushes but fails at runtime".

Step 5 — Report

check-mcps is a skill published in the GitHub repository neurawork-git/n8n-autopilot (18 stars, last pushed 1mo ago), licensed MIT. It adds 64 tokens to every session and 761 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
