Execute NPM packages as AI agent tools - a flexible alternative to MCPs
기본적으로 소스를 먼저 확인하는 Prompt가 선택됩니다. 직접 명령으로 전환하거나 로컬 사본을 다운로드할 수도 있습니다.
설치 여부를 결정하기 전에 SKILL.md와 SkillsMP에 표시된 보조 파일을 읽어 보세요.

You have access to a curated library of 289 high-quality NPM packages that can be executed as tools via bash. This provides flexible, powerful capabilities that go beyond what MCPs offer.
The manifest at data/packages.json contains all available packages with execution patterns.
npx -y <package> [args]
The -y flag auto-confirms installation.
node -e "const pkg = require('<package>'); /* code */"
.js filenode script.js# Resize image
node -e "require('sharp')('input.png').resize(300).toFile('output.png')"
# Convert to JPEG
node -e "require('sharp')('input.png').jpeg({quality: 80}).toFile('output.jpg')"
# Get metadata
node -e "require('sharp')('image.png').metadata().then(m => console.log(JSON.stringify(m, null, 2)))"
# Parse CSV file
node -e "require('fs').createReadStream('data.csv').pipe(require('csv-parse').parse({columns:true})).on('data', r => console.log(JSON.stringify(r)))"
# Quick parse with papaparse
node -e "console.log(JSON.stringify(require('papaparse').parse(require('fs').readFileSync('data.csv','utf8'), {header:true}).data))"
# GET request
node -e "require('axios').get('https://api.example.com/data').then(r => console.log(JSON.stringify(r.data)))"
# POST request
node -e "require('axios').post('https://api.example.com/data', {key: 'value'}).then(r => console.log(r.status))"
# Current date formatted
node -e "console.log(require('dayjs')().format('YYYY-MM-DD HH:mm:ss'))"
# Add 7 days
node -e "console.log(require('dayjs')().add(7, 'day').format('YYYY-MM-DD'))"
# Validate with AJV
node -e "const Ajv = require('ajv'); const v = new Ajv(); console.log(v.validate({type: 'object', required: ['name']}, {name: 'test'}))"
# Parse YAML
node -e "console.log(JSON.stringify(require('js-yaml').load(require('fs').readFileSync('config.yaml', 'utf8'))))"
# Convert JSON to YAML
node -e "console.log(require('js-yaml').dump({key: 'value', nested: {a: 1}}))"
# Find all JS files
node -e "require('glob').glob('**/*.js', {ignore: 'node_modules/**'}).then(f => console.log(f.join('\n')))"
# Create ZIP archive
node -e "const a = require('archiver')('zip'); a.pipe(require('fs').createWriteStream('archive.zip')); a.directory('src/', false); a.finalize()"
# Convert markdown to HTML (CLI)
npx marked -i README.md -o README.html
# Programmatic (marked is ESM-only, use import())
node -e "import('marked').then(m => console.log(m.parse('# Hello\n\nWorld')))"
# Handlebars
node -e "console.log(require('handlebars').compile('Hello {{name}}!')({name: 'World'}))"
# EJS
node -e "console.log(require('ejs').render('Hello <%= name %>!', {name: 'World'}))"
# Read Excel file
node -e "const XLSX = require('xlsx'); const wb = XLSX.readFile('file.xlsx'); console.log(JSON.stringify(XLSX.utils.sheet_to_json(wb.Sheets[wb.SheetNames[0]])))"
node -e "const {jsPDF} = require('jspdf'); const doc = new jsPDF(); doc.text('Hello World', 10, 10); require('fs').writeFileSync('output.pdf', Buffer.from(doc.output('arraybuffer')))"
# UUID v4
node -e "console.log(require('uuid').v4())"
# NanoID (ESM-only, use import())
node -e "import('nanoid').then(m => console.log(m.nanoid()))"
# MD5 hash
node -e "console.log(require('crypto-js').MD5('hello').toString())"
# SHA256
node -e "console.log(require('crypto-js').SHA256('hello').toString())"
-y with npx to auto-confirm package installationSome modern packages are ESM-only and cannot use require(). Use import() instead:
CommonJS packages (most packages):
node -e "console.log(require('dayjs')().format('YYYY-MM-DD'))"
ESM-only packages (use dynamic import):
node -e "import('nanoid').then(m => console.log(m.nanoid()))"
node -e "import('marked').then(m => console.log(m.parse('# Hello')))"
Known ESM-only packages:
nanoid (v4+)marked (v5+)chalk (v5+)ora (v6+)execa (v6+)got (v12+)node-fetch (v3+)How to detect ESM packages:
ERR_REQUIRE_ESM or require is not defined"type": "module"Pattern for ESM:
node -e "import('<package>').then(m => { /* use m.functionName() */ })"
