# Available Tools

The AI can use these tools to help you:

# # search_icons

Search The Noun Project icon database.

What you can filter:

• Style: solid, line, or both
• Line weight: 1-60 or range like "18-20"
• Public domain: Show only free-to-use icons
• Thumbnail size: 42, 84, or 200 pixels
• Include SVG: Get SVG URLs in results
• Limit: Max results per page

Example:

"Search for 'coffee' icons in solid style, public domain only"

# # get_icon

Get detailed information about a specific icon.

Returns:

• Icon name and ID
• Creator information
• Tags and collections
• License details
• Download URLs

Example:

"Show me details for icon 12345"

# # download_icon

Download an icon with custom options.

Options:

• Format: SVG or PNG
• Color: Any hex color (e.g., "FF0000" for red)
• Size: 20-1200 pixels (PNG only)
• Save to file: Optional file path

Note: FREE tier can only download public domain icons.

Example:

"Download icon 12345 as PNG, 200x200, red color, save to ./icons/coffee.png"

# # search_collections

Find icon collections by keyword.

Example:

"Search for 'travel' collections"

# # get_collection

View a specific collection with all its icons.

Example:

"Show me collection 456"

# # icon_autocomplete

Get search term suggestions (max 10).

Example:

"What terms start with 'comp'?"

# # check_usage

Check your API usage and limits.

Shows:

• Monthly limit and usage
• Remaining calls
• Percentage used
• Days until reset
• Optimization tips (FREE tier)

# FREE Tier Best Practices

Maximize your 5,000 monthly calls:

# # 1. Be Specific

Bad:  "icon"       → Too broad, many pages needed
Good: "coffee cup" → Specific, better results

# # 2. Use Autocomplete First

Step 1: "Suggestions for 'cof'"  → ["coffee", "coffee cup"]
Step 2: "Search for 'coffee cup'" → Exact results

# # 3. Avoid Pagination

Bad:  Browsing 5 pages = 5 API calls
Good: Refine search to get results on first page

# # 4. Download Once, Reuse

Download icon → Save to project → Use everywhere
(Don't re-download the same icon)

# # 5. Filter for Public Domain

FREE tier can only download public domain icons
Filter searches with limit_to_public_domain=1

# # 6. Cache Results

The server automatically caches usage data for 5 minutes.
You should also save:

• Downloaded icons
• Icon IDs you've explored
• Collection information

# Cost Optimization

The server automatically optimizes API usage in FREE tier mode:

| Feature | FREE Tier | PAID Tier |
|- -- -- -- --|- -- -- -- -- --|- -- -- -- -- --|
| Results per page | 10 max | 100 max |
| Default thumbnail | 42px | 84px |
| SVG URLs | Excluded | Included |
| Pagination warnings | Yes | No |
| Usage alerts | 50%, 80%, 95% | None |

# Troubleshooting

# # "Missing required environment variables"

Problem: API keys not found.

Solution:

1. Check .env file exists
2. Verify NOUN_CONSUMER_KEY and NOUN_CONSUMER_SECRET are set
3. Check for typos in variable names

# # "Authentication failed"

Problem: Invalid API credentials.

Solution:

1. Verify credentials at developers page
2. Make sure you copied the entire key/secret
3. Check for extra spaces or quotes

# # "Rate limit exceeded"

Problem: Too many requests too fast.

Solution:

• Wait a moment (limit is 100 requests/minute)
• The server automatically handles rate limiting
• If persistent, check your usage with check_usage tool

# # SVG URLs Not Working

Problem: SVG URLs expire after 1 hour.

Solution:

• Download fresh URLs when needed
• Use download_icon to get base64-encoded icons
• Save icons locally instead of relying on URLs

# # "Free API access is limited to public domain icons"

Problem: Trying to download non-public-domain icon with FREE account.

Solution:

• Filter searches: limit_to_public_domain=1
• Or upgrade to PAID tier at pricing page

# # Server Not Appearing in Cursor/Claude

Problem: MCP server not detected.

Solution:

1. Restart Cursor AI or Claude Desktop
2. Check JSON config syntax (no trailing commas!)
3. Verify file paths are absolute
4. Check server logs for errors

# API Limits

| Tier | Monthly Limit | Rate Limit | Download Access |
|- -- -- -|- -- -- -- -- -- -- --|- -- -- -- -- -- -|- -- -- -- -- -- -- -- --|
| FREE | 5,000 calls | 100/min | Public domain only |
| PAID | Unlimited | 100/min | All icons |
