- Progressive Search - Find tokens by name, symbol, or homepage URL with fuzzy matching
- Symbol Variation Handling - Automatically handles rebrands (RNDR→RENDER, MATIC→POL)
- Homepage Verification - Verify token identity by matching website URLs
- Market Data - Get latest prices, volume, market cap, and price changes
- Token Metadata - Retrieve descriptions, logos, social links, and platform info
- Exchange Info - Look up exchange metadata and trading data
Quick Start

Step 2: Store API Key
Add to your ~/.env.local:
COINMARKETCAP_API_KEY=your-api-key-here
# Or alternatively:
CMC_API_KEY=your-api-key-hereStep 3: Configure Claude Code
Add to your ~/.claude.json under mcpServers:
{
"coinmarketcap": {
"command": "uvx",
"args": ["coinmarketcap-mcp"],

Progressive Search
The search_cryptocurrency tool uses multiple strategies to find tokens:
- Exact symbol match (high confidence)
- Symbol variations - handles rebrands like RNDR→RENDER (medium confidence)
- Slug matching - matches by name slug (medium confidence)
- Fuzzy name search - searches 5000+ tokens by similarity (low confidence)
- Homepage verification - boosts confidence by matching website URLs
Example
Query: name="Render Token", symbol="RNDR", homepage="https://rendernetwork.com"
Search log:
- exact_symbol(RNDR): failed (symbol was renamed)
- symbol_variation(RENDER): 1 found
- homepage_verification: exact match
Result: Render (RENDER) - id=5690, confidence=verifiedExample Queries
"Search for a token named 'Uniswap' with homepage 'https://uniswap.org'"
"Is RENDER listed on CoinMarketCap?"
"Get the profile and description for Chainlink"
"What's the current price and market cap of BTC and ETH?"
