CoinMarketCap MCP Skill

You have access to CoinMarketCap data through MCP tools. Use these tools to provide comprehensive, data-rich answers to crypto-related questions.

Prerequisites

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"
      }
    }
  }
}

Core Principle

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.

Workflow

1. Always Search First

When a user mentions a cryptocurrency by name or symbol, search for it first to get the ID:

User: "How is Solana doing?"
β†’ Call search_cryptos with query "solana"
β†’ Get ID (e.g., 5426)
β†’ 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.

2. Batch Requests When Useful

When dealing with multiple coins, batch the requests:

User: "Compare BTC, ETH, and SOL"
β†’ Search for each to get IDs: 1, 1027, 5426
β†’ 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.

3. Match Tools to Query Type

For price and market data:

  • get_crypto_quotes_latest returns price, market cap, volume, percent changes (1h, 24h, 7d, 30d, 90d, 1y), circulating supply, and dominance

    • For coin background and links:

  • get_crypto_info returns description, website, social links, explorer URLs, tags, and launch date

    • For technical analysis:

  • get_crypto_technical_analysis returns moving averages (SMA, EMA), MACD, RSI, Fibonacci levels, and pivot points

    • For recent news:

  • get_crypto_latest_news returns headlines, descriptions, content, URLs, and publish dates

    • For holder and distribution data:

  • get_crypto_metrics returns address counts by holding value, whale vs others distribution, and holder time breakdowns (traders, cruisers, holders)

    • For concept explanations:

  • search_crypto_info performs semantic search on crypto concepts, whitepapers, and FAQs

    • For overall market health:

  • get_global_metrics_latest returns total market cap, fear/greed index, altcoin season index, BTC/ETH dominance, volume, and ETF flows

    • For derivatives and leverage data:

  • get_global_crypto_derivatives_metrics returns open interest, funding rates, liquidations, and futures vs perpetuals breakdown

    • For total market cap technical analysis:

  • get_crypto_marketcap_technical_analysis returns TA indicators for the entire crypto market cap

    • For trending themes:

  • trending_crypto_narratives returns hot narratives with market cap, volume, performance, and top coins in each narrative

    • For upcoming catalysts:

  • get_upcoming_macro_events returns scheduled events like Fed meetings, regulatory deadlines, and major announcements

    • Error Handling

    If search returns no results: 1. Report that the coin was not found 2. Ask the user to clarify or check the spelling 3. Suggest alternatives if the query might be ambiguous

    If a tool fails or times out: 1. Retry once for transient errors 2. If still failing, note which data is unavailable and proceed with other tools 3. For price queries, get_crypto_quotes_latest is critical. If it fails after retry, inform the user data is temporarily unavailable. 4. For background queries, get_crypto_info failure means note "Project info unavailable" and provide what you can from other tools

    If rate limited (429 error): 1. Inform the user the API is rate limited 2. Suggest waiting a moment before retrying 3. Consider if fewer tool calls could answer the question

    Adapting to User Sophistication

    Read context cues from the user's query:

  • Casual questions ("how's bitcoin doing?") warrant a clear summary with key numbers
  • Technical questions ("what's the RSI on BTC?") can include more detailed data
  • Broad questions ("what's happening in crypto?") benefit from market-wide tools like global metrics and trending narratives

    • βš™οΈ Configuration

    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"
      }
    }
  }
