What is n8nctrl AGENTS.md?

Repository instructions for an n8n tool package, where n8n is a workflow automation platform.

They guide development, testing, type checking, building, and adding tools for n8n workflows, executions, tags, credentials, and security audits.

They define the required checks, project structure, configuration, and safety limits for changes to the package and its live automations.

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	$0.01159	$0.01159
Opus 5	$0.00580	$0.00580
Sonnet 5	$0.00232	$0.00232
Haiku 4.5	$0.00116	$0.00116

Security

Grade A, and why

n8nctrl AGENTS.md scanned grade A with 0 findings 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 2d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Guidance

Definition of Done

./scripts/verify

Runs npm test, npm run typecheck, and npm run build in order.

A change is done only when all three pass, re-verified after your last edit:

npm test
npm run typecheck
npm run build

Report the actual results you observed. If anything fails, report the failure verbatim and do not claim success. Never describe a change as complete with a failing or unrun check.

Project Shape

TypeScript package exposing ops-focused n8n tools (workflow + execution lifecycle, tags, credentials metadata, security audit, composed scanners) two ways: a stdio MCP server and an OpenClaw plugin.
mcp-server.ts is the MCP entry point (config from N8N_BASE_URL, N8N_API_KEY, N8N_ENABLE_EDIT, etc.). index.ts is the OpenClaw plugin entry point (config via resolveConfig() in src/config.ts).
Tools live one per file under src/tools/ as create<Name>Tool(getClient) factories. There is no central tool index.
HTTP access goes through N8nClient in src/client.ts. ESM, Node >= 20, builds with tsup to dist/.

Hard Prohibitions

The live n8n instance runs real automations. Never run write tools against it during development or review unless the user explicitly asks in this session. That includes scripts/smoke.ts, npm run dev, and ad hoc tool calls. Tests use mocked fetch helpers and need no instance.
Never weaken the enableEdit gate, the enableCredentialsWrite gate, or the runtime confirm: true requirement. If a gate blocks the task, report the blocker to the user; do not route around it.
Never weaken or remove the pre-write backups or the backupDir path confinement (details below).
Never weaken, skip, or delete a failing test to make a run green. Fix the code or report the failure.
Never push with --no-verify. hooks/pre-push runs content-guard for a reason; fix the flagged content instead.
Hit any other blocker (missing creds, ambiguous spec, broken tooling): stop and report it exactly. Do not invent a workaround that bypasses a safety rule.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
