Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00083 | $0.01906 |
| Opus 5.5 | $0.00033 | $0.00762 |
| Sonnet 5.5 | $0.00017 | $0.00381 |
| Haiku 4.5 | $0.00008 | $0.00191 |
Grade B, and why
n8n scanned grade B with 2 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
**Do NOT suggest editing `~/.claude/settings.local.json` manually.** `teleport-setup add-key n8n` handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
n8n
Direct REST access to an n8n instance — no MCP required. Covers Public API v1: workflow CRUD + activation, execution inspection/retry/stop, credentials, tags, variables, users, projects.
Usage
- Use for: Listing/filtering workflows, reading execution history, batch activate/deactivate, reading execution I/O programmatically.
- Skip for: Authoring new workflows from scratch (UI is better), interactive debugging, one-off manual test runs.
- Triggering a workflow is a webhook call, not
/api/v1— see Gotchas.
Credentials check
[ -n "$N8N_API_KEY" ] && [ -n "$N8N_BASE_URL" ] && echo "N8N: PRESENT" || echo "N8N: MISSING"
Never echo either variable directly.
If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):
I need your n8n credentials. Run this in another terminal — it walks you through the two values (base URL + API key) and saves them safely:
teleport-setup add-key n8nThen restart Claude Code (
/exit, thenclaude) and ask me again.
Do NOT suggest editing ~/.claude/settings.local.json manually. teleport-setup add-key n8n handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted.
API
- Base URL:
$N8N_BASE_URL/api/v1— self-hosted (https://n8n.mycompany.com,http://localhost:5678) or n8n Cloud (https://<workspace>.app.n8n.cloud). Must include protocol, no trailing slash. - Auth:
X-N8N-API-KEY: $N8N_API_KEY— custom header, NOTAuthorization: Bearer. OpenAPI declaresApiKeyAuthwithin: header, name: X-N8N-API-KEY. Wrong header 401s silently. - API key: n8n UI → Settings → n8n API → Create an API key. Per-user, inherits user's permissions.

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.
- 1mo ago First seen · 113 lines · 83 tokens per session scan B 17c2cfa6aee5
n8n is a skill published in the GitHub repository mnlt/teleport (8 stars, last pushed 6mo ago), licensed MIT. It adds 83 tokens to every session and 1,906 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

cron-task-creator
A scheduler for recurring octo agent tasks. Each task contains a schedule and a prompt, so octo can run an agent turn automatically at the specified times.
workflow-creator
Turn a repeatable multi-step task into a runnable, reusable saved workflow through guided conversation, in either of two shapes — chaining existing skills/recordings (wiring each one's output into the next's input), or composing the workflow script's own primitives (agent/parallel/pipeline) directly when the task…
resume-crafting
A career-writing aid for turning a résumé or cover letter into clear evidence of results. It uses measurable outcomes and adapts the wording to a job description and applicant-tracking systems, or ATS tools that scan applications for relevant terms.
mcptoon
Compress MCP tool discovery with the mcptoon CLI. Trigger when a session has a large MCP tool catalog (many servers/tools), when the user mentions token cost, tool discovery, mcptoon, or asks to list/call MCP tools efficiently. Also route here when the user says the MCP tool list is too large, the agent context window…
