Extract project logo
This skill extracts a project's official logo from its website or related sources, prioritising high-quality vector formats and official brand assets.
Required inputs
Before starting, gather the following from the user:
- Website URL - The project's main website (e.g.,
https://example.com) - Save path - Local filesystem path where the logo should be saved (e.g.,
./logos/example-logo.svg) - Format preference (optional) - Preferred format: SVG (recommended), PNG, or any
If any required input is missing, ask the user before proceeding.
Save all project logos in the target folder. We will pick variants and post-process those later.
There is no universal standard how artist name their logo files for dark and light variants. In our case, we always say
light: light (white) text on dark or transparent backgrounddark: dark (black) text on white or transparent background
Following vocabulary is used:
- Brand mark: same as logo mark, the logo without the brand name text
- Word mark: the logo with the brand name text
Step 1: Search for brand kit or media resources
The highest quality logos are typically found in official brand/media kits. Search for these pages:
- Navigate to the website and look for links in the footer or header:
- "Brand", "Brand Kit", "Brand Assets", "Brand Guidelines" - "Media", "Media Kit", "Press", "Press Kit" - "Resources", "Downloads", "Assets"
- Try common URL patterns:
- {baseurl}/brand - {baseurl}/brand-kit - {baseurl}/media - {baseurl}/press - {baseurl}/assets - {baseurl}/resources
- If a brand kit is found:
- Look for downloadable logo packages (often ZIP files) - Prefer SVG or vector formats over raster images - Choose the most square logo variant if multiple options exist - If both light and dark themes are present, get both - If colourful option exist, get it as well
If a brand kit is found with suitable logos, proceed to Step 5.
Step 2: Check GitHub repository
Many projects host their logos in their GitHub repositories:
- Find the project's GitHub repository (often linked in website footer/header)
- Search these common locations:
- /assets/ or /images/ directories - /branding/ or /brand/ directories - /public/ directory (for web apps) - /docs/ or /documentation/ directories - Root directory (README badges, logo files)
- Check the README.md for embedded logos:
- Look for <img> tags or markdown image syntax - These often point to high-quality logo files
- Search for files named:
- logo.svg, logo.png, logo-.svg - {project-name}.svg, {project-name}-logo. - brand., icon.
If a suitable logo is found, proceed to Step 4.
Step 3: Extract from website directly
If no brand kit or GitHub assets are available, extract the logo from the website:
Option A: Using MCP Playwright (recommended for dynamic sites)
Use the MCP Playwright tool to:
- Navigate to the homepage
- Look for logo elements in the header (typically top-left):
- Search for <img> tags with class/id containing "logo" - Check for <svg> elements in the header - Look for elements with role="img" and logo-related aria labels
- Extract the image source URL or SVG content
Option B: Check meta tags and favicon
- Open Graph image - Check for
<meta property="og:image">tag
- Often a high-quality image suitable for social sharing - May include branding elements
- Favicon - Check for high-resolution favicon:
- <link rel="icon" type="image/svg+xml"> (best - vector) - <link rel="apple-touch-icon"> (usually 180x180 PNG) - /favicon.ico (low resolution, last resort)
- Twitter Card image - Check
<meta name="twitter:image">
Step 4: Extract from Twitter
Get the project logo from their Twitter (also known as X.com) avatar image.
Step 5: Extract from Coingecko
Get the project logo from their Coingecko.
Step 6: Download and save
- For SVG files:
- Download the raw SVG content - Ensure the file is valid XML - Save with .svg extension
- For raster images (PNG, etc.):
- Download the highest resolution available - Verify file integrity after download - Save with appropriate extension
- Verify the saved file:
- Open the file to confirm it displays correctly - Check file size is reasonable (not 0 bytes or corrupted)
Download methods
Using curl:
curl -o "{save_path}" "{logo_url}"
Using Python:
import requests
response = requests.get("{logo_url}")
with open("{save_path}", "wb") as f:
f.write(response.content)
For SVG content extracted directly:
with open("{save_path}", "w") as f:
f.write(svg_content)
Step 7: Report results to user
Provide the user with:
- Source location - Where the logo was found (brand kit URL, GitHub path, etc.)
- File details - Format, dimensions (for raster), file size
- Saved path - Confirm where the file was saved
- Alternative versions - Note if other variants are available (dark mode, icon-only, etc.)
Step 8: Save the report as Markdown file next to the logos
- Create a Markdown file in the folder where logos where saved
- Include the same information as for the user report
- Include links to the web pages, brand pages and brand kits used
Troubleshooting
No logo found
If no suitable logo can be found:
- Check if the project uses a different primary domain
- Look for the project on social media (Twitter/X, LinkedIn) - profile images are often logos
- Search "[project name] logo" on image search engines
- Check DeFiLlama, CoinGecko, or similar aggregators for crypto projects
- Ask the user if they have alternative sources or contacts
Dynamic/JavaScript-rendered logos
If the logo is rendered via JavaScript:
- Use MCP Playwright to load the page fully
- Wait for dynamic content to render
- Extract from the rendered DOM
Logo requires authentication
If brand assets are behind a login:
- Inform the user
- Provide the URL to the brand kit page
- Ask the user to download manually or provide credentials (if appropriate)
