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.

Built by Whoff Agents.

Installation

Quick Start (recommended)

# Clone the repo
git clone https://github.com/whoff-agents/crypto-data-mcp.git
cd crypto-data-mcp

# Install with uv (recommended)
uv sync

# Or install with pip
pip install -e .

From PyPI (coming soon)

pip install crypto-data-mcp

Usage with Claude Code

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

{
  "mcpServers": {
    "crypto-data": {
      "command": "uv",
      "args": [
        "--directory", "/path/to/crypto-data-mcp",
        "run", "crypto-data-mcp"
      ]
    }
  }
}

Or if installed globally via pip:

{
  "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?"

Supported Tokens

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.

Data Source

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

• 60-second caching to reduce API calls
• Automatic retry with backoff on rate limits
• Graceful error handling for network issues and invalid inputs

The free CoinGecko tier allows approximately 10-30 requests per minute.

Development

# 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

Pricing

Free tier -- This open-source MCP server with CoinGecko data is free.

Pro tier -- Coming soon at $19/mo with:

• Real-time WebSocket price feeds
• DEX data (Uniswap, Raydium, Jupiter)
