Installation

# Run directly with npx (no installation needed)
npx @entro314labs/web-icons-generator-cli-mcp source.svg

# Shorter aliases
npx @entro314labs/web-icons-generator-cli-mcp@latest
# After install: create-icons, webicons, or web-icons-generator-cli-mcp

# Or install globally
npm install -g @entro314labs/web-icons-generator-cli-mcp
create-icons  # shortest command!
webicons     # also works

Usage

Zero Config (Recommended)

# Place app-icon.svg or app-icon.png in your project root
cd my-project
npx @entro314labs/web-icons-generator-cli-mcp
# ✓ Found app-icon.svg in current directory
# ✓ Detected Next.js → using public/ directory
# ✨ Success! Generated 8 files

Basic Usage

# With source file as argument
npx @entro314labs/web-icons-generator-cli-mcp logo.svg

# Or if installed globally (use shorter commands)
create-icons logo.svg
webicons logo.svg

# Interactive mode (prompts for source if not found)
create-icons

Advanced Options

# Specify output directory
create-icons logo.svg --output ./public

# Custom Safari pinned tab color
create-icons logo.svg --color "#ff5733"

# Choose generation mode
create-icons logo.svg --mode nextjs    # Next.js App Router (app/)
create-icons logo.svg --mode traditional  # Traditional web app (public/)
create-icons logo.svg --mode auto      # Auto-detect (default)

# Full example
create-icons logo.svg -o ./app -m nextjs -c "#1a1a1a"

Generation Modes

The tool supports two generation modes for maximum compatibility:

🚀 Next.js App Router Mode (`--mode nextjs`)

Perfect for Next.js 13+ with App Router

Generated files (in app/ directory):

favicon.ico (32×32)
icon.png (512×512) - auto-linked by Next.js
apple-icon.png (180×180) - auto-linked by Next.js
apple-touch-icon.png (180×180) - for compatibility
icon.svg (if source is SVG) - auto-linked by Next.js

Benefits:

✅ Zero configuration - icons auto-linked by Next.js
✅ No manual <head> tags needed
✅ Automatic metadata generation
✅ Cleaner project structure

Usage:

create-icons logo.svg --mode nextjs
# or let it auto-detect
create-icons logo.svg  # detects Next.js App Router automatically

📁 Traditional Mode (`--mode traditional`)

Perfect for all other frameworks and traditional web apps

Generated files (in public/ directory):

favicon.ico (32×32)
icon.svg (scalable)
icon-192.png (192×192) - for PWA
icon-512.png (512×512) - for PWA
apple-touch-icon.png (180×180)
icon-maskable.png (512×512, with padding) - for Android
safari-pinned-tab.svg (monochrome) - for Safari
site.webmanifest (PWA manifest)

Requires: Manual HTML integration (copy from html-snippet.txt)

Usage:

create-icons logo.svg --mode traditional

Generated Files

Traditional Mode generates these files in your output directory:

/public/
  ├── favicon.ico              (32×32)
  ├── icon.svg                 (scalable)
  ├── icon-192.png             (192×192)
  ├── icon-512.png             (512×512)
  ├── apple-touch-icon.png     (180×180)
  ├── icon-maskable.png        (512×512, with padding)
  ├── safari-pinned-tab.svg    (monochrome)
  └── site.webmanifest         (PWA manifest)

/  (project root)
  └── icon-integration-guide.txt  (HTML snippet to copy)

Next.js App Router Mode generates these files in your app directory:

/app/  (or /src/app/)
  ├── favicon.ico              (32×32)
  ├── icon.png                 (512×512, auto-linked)
  ├── icon.svg                 (scalable, auto-linked)
  ├── apple-icon.png           (180×180, auto-linked)
  └── apple-touch-icon.png     (180×180, compatibility)

/  (project root)
  └── icon-integration-guide.txt  (integration instructions)

Framework Detection

The tool automatically detects your framework and uses the correct output directory and mode:

Framework	Config File	Default Mode	Output Directory
Next.js (App Router)	`next.config.js` + `app/`	`nextjs`	`app/`
Next.js (Pages)	`next.config.js`	`traditional`	`public/`
Astro	`astro.config.mjs`	`traditional`	`public/`
SvelteKit	`svelte.config.js`	`traditional`	`static/`
Remix	`remix.config.js`	`traditional`	`public/`
Vite	`vite.config.js`	`traditional`	`public/`
Default	None detected	`traditional`	`public/`

HTML Integration

Next.js App Router (Auto-Linked)

No manual HTML needed! Next.js automatically generates these tags:

<link rel="icon" href="/favicon.ico" sizes="any" />
<link rel="icon" href="/icon.png" type="image/png" sizes="512x512" />
<link rel="apple-touch-icon" href="/apple-icon.png" />
<link rel="icon" href="/icon.svg" type="image/svg+xml" />

Traditional Mode (Manual Integration)

After generation, copy the contents of icon-integration-guide.txt to your HTML <head>:

<!-- Favicon (modern + fallback) -->
<link rel="icon" href="/icon.svg" type="image/svg+xml">
<link rel="icon" href="/favicon.ico" sizes="any">

<!-- Apple Touch Icon -->
<link rel="apple-touch-icon" href="/apple-touch-icon.png">

<!-- Web App Manifest (PWA) -->
<link rel="manifest" href="/site.webmanifest">

<!-- Safari Pinned Tab -->
<link rel="mask-icon" href="/safari-pinned-tab.svg" color="#5bbad5">

AI Assistant Integration

After generation, the tool provides an AI-ready prompt you can use with Claude, ChatGPT, or other assistants to verify your setup:

I generated web app icons in the [directory] for this [framework] app.
Please read the integration guide at icon-integration-guide.txt and verify
that all icon files are correctly placed and properly integrated.

Requirements

Node.js 18 or higher
Source image in SVG, PNG, or JPG format
For best results, use square SVG with transparent background

Supported Input Formats

.svg – Recommended (scalable, generates all files)
.png – Good (generates raster icons, SVG files need manual creation)
.jpg/.jpeg – Acceptable (generates raster icons, SVG files need manual creation)

How It Works

Looks for app-icon.svg or app-icon.png in current directory (or uses provided path)
Detects your framework (Next.js, Astro, etc.) and determines the best generation mode
Auto-selects mode: Next.js App Router → nextjs mode, others → traditional mode
Converts & resizes your source image to all required sizes for the selected mode
Generates maskable icon with proper 20% safe zone padding (traditional mode)
Creates monochrome SVG for Safari pinned tabs (SVG sources only, traditional mode)
Generates manifest with correct icon references (traditional mode)
Outputs integration guide in html-snippet.txt

Why This Tool?

Most icon generators are:

❌ Outdated (generate 30+ unnecessary files)
❌ Online-only (require uploading your logo)
❌ Not framework-aware (manual directory setup)
❌ Missing modern features (maskable icons, SVG favicons)
❌ Don't support Next.js App Router conventions

This tool:

✅ Generates only what you need (2025 standards)
✅ Works offline (CLI-based)
✅ Auto-detects your framework
✅ Includes modern PWA features
✅ Supports Next.js App Router with zero-config auto-linking
✅ Dual-mode support: traditional web apps + Next.js

Examples

Example 1: Zero Config (Recommended)

cd my-nextjs-app
# Create app-icon.svg in the project root
create-icons
# ✓ Found app-icon.svg in current directory
# ✓ Detected Next.js → using public/ directory
# ✨ Success! Generated 8 files

Example 2: Next.js Project with Custom Path

cd my-nextjs-app
create-icons assets/logo.svg
# ✓ Detected Next.js → using public/ directory
# ✨ Success! Generated 8 files

Example 3: Custom Output

create-icons assets/brand.svg --output static/icons
# Generated icons in static/icons/

Example 4: Brand Color

create-icons logo.svg --color "#ff6b35"
# Safari pinned tab will use #ff6b35

Browser Support

File	Supported Browsers
`favicon.ico`	All browsers (legacy fallback)
`icon.svg`	Chrome 80+, Firefox 41+, Safari 9+
`apple-touch-icon.png`	iOS Safari, macOS Safari
`icon-192.png`, `icon-512.png`	Chrome/Edge (PWA), Android
`icon-maskable.png`	Android 13+ (adaptive icons)
`safari-pinned-tab.svg`	Safari 9+ (pinned tabs)

Troubleshooting

"Source file not found"

Ensure the path to your source image is correct
Use relative or absolute paths: ./logo.svg or /Users/you/project/logo.svg

"Invalid file format"

Only SVG, PNG, and JPG are supported
Convert other formats (WebP, GIF) to PNG first

Icons not displaying

Ensure files are at domain root (https://yourdomain.com/favicon.ico)
Check HTML <head> tags are present
Clear browser cache (hard refresh: Cmd+Shift+R / Ctrl+Shift+R)
