dev-mcp-setup

dev-mcp-setup is a skill for Claude Code, Codex from volomydyr/design-engineer-plugin. It costs 33 tokens per session (1,870 once invoked), scanned A, original, MIT.

A guide for choosing and configuring MCP integrations for AI-assisted development. MCP integrations connect an AI assistant to other tools, such as design files, current documentation, or browser tests.

In plain words
What is it for?
Use it when setting up a development environment with MCP servers, deciding which integrations are useful, and documenting their use for the AI assistant.
Why use it?
It helps avoid installing unnecessary integrations and prompts you to choose tools based on actual workflow needs. It also requires explicit user choices before setup guidance or configuration changes.

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

dev-mcp-setup 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 3d 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.

MCP Setup Guide

Why This Matters

MCPs are integrations between an AI and another application. They extend what AI can do beyond basic code generation – reading Figma designs, fetching up-to-date documentation, running browser tests, and more. However, installing every MCP you find is counterproductive. Start with the essentials and add others only when you have a specific need.

Interaction Method

If AskUserQuestion is available, use it for all prompts below.

If not, present each question as a numbered list and wait for a reply before proceeding. For multiSelect questions, accept comma-separated numbers (e.g. 1, 3). Never skip or auto-answer without explicit user consent.


Step 0: Before starting

  1. Announce your execution plan: Before doing anything, state what you will do in this activity: "Here's what I'm going to do: 1) check which MCPs you already have installed, 2) recommend MCPs based on your workflow needs, 3) provide setup guidance for each one, 4) configure CLAUDE.md references so AI uses them consistently." This is a commitment device – harder to skip steps you just announced.

  2. Conditional teaching: Ask the user if they are familiar with what MCPs are and how they extend AI capabilities. If yes, give a one-sentence refresher. If no, explain it in simple terms: MCPs are integrations between AI and other applications – they let AI read Figma designs, fetch current documentation, run browser tests, and more, instead of being limited to just generating code.

    Required: ALWAYS ask the question, ALWAYS give the refresher when the user says yes. Never skip this step because the user "is a designer" or "already demonstrated familiarity earlier." Users want a memory refresh on every activity, including ones they know. Phrases like "I'll skip the explainer (you're a designer)" are forbidden — they signal the model has decided ON BEHALF OF the user that a refresher isn't needed. The user, not the model, decides what's redundant. The refresher takes one sentence; the cost is trivial; the value to a tired user mid-session is high.

Changes

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.
