What This Skill Does

The cmc-mcp skill provides the OpenClaw AI agent with deep, real-time access to cryptocurrency market data powered by the CoinMarketCap API. By utilizing the Model Context Protocol (MCP), this skill enables the agent to function as a sophisticated financial analyst. It goes beyond simple price lookups, offering the ability to retrieve comprehensive technical indicators, on-chain holder metrics, global market sentiment through fear/greed indices, and the latest news affecting the blockchain ecosystem. Whether you are tracking a niche token or analyzing total market capitalization, this skill ensures your agent has the data required to provide data-driven insights.

Installation

To integrate this skill into your environment, use the OpenClaw command-line interface. First, ensure you have your API key ready from the CoinMarketCap developer portal. Run the following command in your terminal:

clawhub install openclaw/skills/skills/bryan-cmc/cmc-mcp

After installation, you must configure your MCP server settings. Locate your configuration file and add the server definition:

{
  "mcpServers": {
    "cmc-mcp": {
      "url": "https://mcp.coinmarketcap.com/mcp",
      "headers": { "X-CMC-MCP-API-KEY": "your-api-key" }
    }
  }
}

Restart your agent environment to finalize the connection.

Use Cases

This skill is designed for versatility across several domains:

1. Portfolio Monitoring: Fetch real-time price updates and percentage changes for any asset, allowing for instant portfolio health checks.
2. Technical Analysis: Use advanced indicators like RSI, MACD, and Fibonacci levels to aid in identifying potential entry or exit points.
3. Market Sentiment Analysis: Use global market metrics and news tools to gauge the overall mood of the crypto market, including ETF flows and altcoin season status.
4. Research and Due Diligence: Quickly pull whitepaper links, explorer addresses, and social media data to vet new tokens before engaging with them.

Example Prompts

• "How is Solana doing compared to Ethereum right now? Include price, volume, and recent technical analysis."
• "What is the current Fear and Greed index, and are there any major news headlines affecting Bitcoin today?"
• "Can you provide a holder distribution breakdown for PEPE and tell me if there is any significant whale activity?"

Tips & Limitations

To maximize the utility of this skill, always prioritize the search tool first; most API calls rely on specific numeric CMC IDs rather than ticker symbols. For complex queries involving multiple assets, batch your requests to reduce API latency. Keep in mind that while the technical analysis indicators are powerful, they are tools for data visualization and should not be considered professional financial advice. Always verify API connection status if tools return empty or error responses.
