Crypto Data MCP

Real-time cryptocurrency data for AI coding tools. An MCP server that gives Claude Code, Cursor, and other MCP-compatible tools access to live prices, market data, token info, and historical charts -- powered by CoinGecko.

Fastest: one-liner with uvx (no install needed)

pip install crypto-data-mcp # or uv add crypto-data-mcp

git clone https://github.com/Wh0FF24/crypto-data-mcp.git cd crypto-data-mcp uv sync

Add to your Claude Code MCP config at~/.claude/claude_desktop_config.json:

{ "mcpServers": { "crypto-data": { "command": "uvx", "args": ["crypto-data-mcp"] } } }

{ "mcpServers": { "crypto-data": { "command": "crypto-data-mcp" } } }

Then in Claude Code, you can ask things like:

- "What's the current price of Bitcoin?"
- "Compare ETH, SOL, and AVAX prices"
- "Show me the crypto market overview"
- "Get me 30 days of BTC price history"
- "What's Ethereum's all-time high?"

Get the current price for a single token.

{ "symbol": "BTC", "coingecko_id": "bitcoin", "currency": "usd", "price": 67250.00, "price_change_24h_pct": -1.82, "market_cap": 1325000000000, "volume_24h": 28500000000, "last_updated_at": 1712000000 }

Get prices for multiple tokens in one call. More efficient than callingget_pricerepeatedly.

[ { "symbol": "BTC", "price": 67250.00, "price_change_24h_pct": -1.82 }, { "symbol": "ETH", "price": 2064.00, "price_change_24h_pct": -2.15 }, { "symbol": "SOL", "price": 79.00, "price_change_24h_pct": -3.10 } ]

Get a crypto market overview with top movers, market cap, and sentiment.

{ "total_market_cap_usd": 2390000000000, "total_volume_24h_usd": 85000000000, "btc_dominance_pct": 55.95, "eth_dominance_pct": 11.20, "active_cryptocurrencies": 17887, "fear_greed_index": { "value": 35, "classification": "Fear" }, "top_gainers_24h": [ "..." ], "top_losers_24h": [ "..." ] }

Get detailed information about a token including description, supply, ATH/ATL, and multi-timeframe price changes.

{ "symbol": "ETH", "name": "Ethereum", "description": "Ethereum is a decentralized...", "market_cap_rank": 2, "website": "https://www.ethereum.org/", "current_price_usd": 2064.00, "ath_usd": 4946.05, "ath_date": "2021-11-10T14:24:19.604Z", "atl_usd": 0.432979, "circulating_supply": 120500000, "total_supply": 120500000, "max_supply": null, "price_change_24h_pct": -2.15, "price_change_7d_pct": -5.30, "price_change_30d_pct": -12.40 }

Get historical price data as timestamp/price pairs for charting and analysis.

Granularity:5-minute for 1 day, hourly for 1-90 days, daily for 90+ days.

{ "symbol": "BTC", "currency": "usd", "days": 7, "data_points": 168, "prices": [ [1711900000000, 67100.00], [1711903600000, 67250.00] ] }

The server includes a built-in mapping for 70+ popular tokens (BTC, ETH, SOL, USDT, USDC, BNB, XRP, ADA, DOGE, AVAX, and many more). For tokens not in the built-in map, it automatically searches CoinGecko to resolve the symbol.

All data comes from theCoinGecko API(free tier). The server includes:

# Install dependencies uv sync # Run tests (uses live CoinGecko API -- may hit rate limits) uv run pytest tests/ -v # Run the server directly uv run crypto-data-mcp
