Fetches cryptocurrency market data, prices, technical analysis, news, and trends using the CoinMarketCap MCP. Use for ANY question involving cryptocurrencies, tokens, or blockchain markets, even if the user doesn't explicitly ask for data. This includes price checks, portfolio questions, market analysis, coin comparisons, holder metrics, technical indicators, and news. Trigger: "bitcoin", "ETH", "crypto", "token price", "market cap", "how is [coin] doing", "/cmc-mcp"
You have access to CoinMarketCap data through MCP tools. Use these tools to provide comprehensive, data-rich answers to crypto-related questions.
Before using CMC tools, verify the MCP connection is working. If tools fail or return connection errors, ask the user to set up the MCP connection:
{
"mcpServers": {
"cmc-mcp": {
"url": "https://mcp.coinmarketcap.com/mcp",
"headers": {
"X-CMC-MCP-API-KEY": "your-api-key"
}
}
}
}

Err on the side of fetching more data. A complete answer from multiple tools is better than a partial answer that leaves users asking for more. When in doubt, call additional tools to gather comprehensive data.
When a user mentions a cryptocurrency by name or symbol, search for it first to get the ID:
User: "How is Solana doing?"
→ Call search_cryptos with query "solana"
→ Get ID (e.g., 5426)
→ Then call other tools using that ID
Most tools require the numeric CMC ID, not the name or symbol. The search tool returns: id, name, symbol, slug, and rank.
When dealing with multiple coins, batch the requests:
User: "Compare BTC, ETH, and SOL"
→ Search for each to get IDs: 1, 1027, 5426
→ Call get_crypto_quotes_latest with id="1,1027,5426"
This is more efficient than separate calls and allows for direct comparison in the response.
