cmc-mcp_skill

Overview

This skill connects to the CoinMarketCap MCP to fetch live cryptocurrency market data, prices, technical analysis, news, holder metrics, and market-wide indicators. It is designed to answer any question about coins, tokens, or blockchain markets with data-driven responses and actionable context. Use it when you need reliable CMC-sourced numbers, charts, or narrative summaries.

How this skill works

The skill first searches for a coin by name or symbol to obtain its numeric CMC ID, then calls the appropriate MCP endpoints (quotes, info, technical analysis, metrics, news, global metrics, narratives) to gather comprehensive data. It favors batching requests for multiple coins, retries transient errors once, and reports which data is unavailable if a tool fails or the API is rate limited. Outputs combine price, market cap, percent moves, supply, TA indicators (RSI/MACD/SMA/EMA), holder distribution, and related news.

When to use it

• Checking live price, market cap, volume, or percent changes for any token
• Comparing multiple coins side-by-side (price, market cap, dominance)
• Requesting technical indicators (RSI, MACD, moving averages, Fibonacci levels)
• Getting recent news, project links, or on-chain holder distribution metrics
• Asking broad market health questions (total market cap, dominance, altcoin season, derivatives)

Best practices

• Always run search first to resolve names into CMC numeric IDs before other calls
• Batch coin IDs when comparing multiple assets to reduce latency and ensure consistent snapshot data
• Retry one time on transient API errors; if rate limited, inform the user and advise retry timing
• Prioritize get_crypto_quotes_latest for price queries; if unavailable, clearly state data limits
• Combine global metrics and trending narratives for market-wide questions to give context, not just single-coin numbers

Example use cases

• "How is Bitcoin performing today?" — returns price, 24h/7d changes, RSI, and recent headlines
• "Compare BTC, ETH, SOL" — batch quote request with market caps, dominance, and percent moves
• "Show me Solana holder distribution" — uses metrics endpoint to summarize whales vs retail and holder time breakdowns
• "What are current market narratives?" — lists trending themes with top coins and performance
• "What's the RSI and SMA on ETH?" — returns technical analysis indicators and short commentary
