n8n-manager

n8n-manager is a skill for Claude Code from psd401/psd-claude-plugins. It costs 96 tokens per session (4,524 once invoked), scanned A, original, MIT.

A tool for building, deploying, and managing n8n workflows on an internal server. n8n is a system for connecting services and automating sequences of actions, often through webhooks, which are URLs that trigger a workflow.

In plain words
What is it for?
Use it to create workflows, check n8n status, manage executions, and connect systems such as Freshservice, PowerSchool, Google Workspace, and Red Rover.
Why use it?
It provides a way to manage automations and connections between internal systems while accounting for the limits of the server's Community Edition. It also keeps server addresses and access keys out of the workflow instructions.

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.

Security

Grade A, and why

n8n-manager scanned grade A 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 14d ago.

The scan reads SKILL.md. This mod also ships 27 executable files (scripts/activate_workflow.js, scripts/create_credential.js, scripts/create_tag.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

n8n Manager

Configuration

  • Server: Read from N8N_HOST environment variable (never hardcoded)
  • API Auth: X-N8N-API-KEY header via N8N_API_KEY env var
  • Instance MCP: Native n8n MCP at N8N_HOST/mcp-server/http (bearer token from N8N_MCP_TOKEN), from the opt-in n8n plugin: /plugin install n8n, then enable it from the Installed tab of /plugin
  • Docs MCP: czlonkowski/n8n-mcp for node documentation and templates
  • Version: n8n Community Edition v2.14.x
  • Scripts: plugins/psd-productivity/skills/n8n-manager/scripts/

All scripts use bun and read credentials from secrets.js (env vars → Geoffrey .env).

Community Edition Limitations

PSD runs n8n Community Edition. These features are not available:

  • No Settings → Variables — environment variables are enterprise/pro only. All config values (API keys, URLs, folder IDs) must be hardcoded directly in workflow node parameters.
  • No instance-level error workflow — must set errorWorkflow in each workflow's settings object individually.
  • Credentials API returns 403 — credential listing/reading is restricted. Get credential IDs from the user via the n8n UI.
  • No source control / Git integration — workflows must be managed via API or UI exports.

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.
