mcphub-operator

mcphub-operator is a skill for Claude Code from wyattowalsh/agents. It costs 39 tokens per session (1,066 once invoked), scanned A, original, MIT.

An operator for MCPHub, a control system that groups and exposes MCP services to coding agents. MCP is a standard way for agents to use external tools.

In plain words
What is it for?
Use it to run preflight checks, inspect groups, configure compression or tunnels, and look up MCPHub command details.
Why use it?
It helps choose service groups and check connection settings before an agent relies on those tools.

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.

Fable 5.1 $0.00039 $0.01066
Opus 5.5 $0.00016 $0.00426

Security

Grade A, and why

mcphub-operator 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 1mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/asset_toolkit/validate_hooks.py, scripts/check.py, scripts/doctor.py, …), 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.

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.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MCPHub Operator

Repo-managed MCPHub control plane: workflow groups, bearer endpoints, optional compression, ChatGPT tunnel policy. Smart Routing stays off in tracked config.

NOT for: editing the agent-stack sync script, live skills-sync apply installs, or PostgreSQL/pgvector smart-routing setup (use maintainer OpenSpec + explicit user request).

Dispatch

$ARGUMENTS Action
(empty) Show group picker summary, preflight command, and reference index
preflight / doctor Run bash scripts/preflight.sh from skill dir; stop on fail
groups / picker Load references/group-picker.md
compression Load references/compression-opt-in.md
tunnel Explain ChatGPT tunnel group-only policy + .env.mcphub tunnel vars
cli Load references/cli-cheatsheet.md

Operator Contract

preflight

  1. From repo root (or pass --cwd to bundled doctor), run:
bash skills/mcphub-operator/scripts/preflight.sh
  1. Stop when JSON ok is false or any check with status: fail touches settings parity, smart routing, or client profiles.
  2. Treat warn as advisory (hub not running, bearer unset locally).

groups

  1. Default local harnesses attach harness only, with per-server endpoints available but disabled by default.
  2. Treat harness as the smallest high-signal set for context-bloat control: Brave Search, DuckDuckGo Search, DDGS (metasearch/news), Context7, DeepWiki, llms.txt catalog (llms-txt-explorer list_websites only), Fetch, and package metadata. Use check_website only via opt-in workflow groups. Prefer DDGS snippets; avoid fetch_full_content unless the user needs full pages.
  3. Use daily for routine opt-in expansion; use coding, research, review, or release for scoped agentic dev flows.
  4. Escalate to capability groups (web-search, web-read, docs, repo, browser, media, notebooks, data, design, productivity, accounts, references) when the task needs that surface.
  5. Use reasoning only for hard problems; keep reasoning-lab experimental.
  6. Attach account-backed, live-browser (Chrome DevTools and Scrapling headless scrape sessions), heavy, or experimental groups only with explicit user intent.
  7. Never attach tunnel to local harness configs unless testing the remote consumer shape.

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.
