CoinMarketCap Data MCP Server

Overview

CoinMarketCap Data is a Model Context Protocol server that provides access to cryptocurrency market data through the CoinMarketCap API. This server enables AI assistants to retrieve real-time information about cryptocurrencies, including market listings, price quotes, and detailed coin information.

Prerequisites

Before using this MCP server, you'll need:

1. A CoinMarketCap API key (obtain one from CoinMarketCap's website)
2. Python installed on your system

Installation Options

Option 1: Install via Smithery (Recommended)

The easiest way to install CoinMarketCap Data is through Smithery:

npx -y @smithery/cli install coin-api-mcp --client claude

Option 2: Manual Installation

1. Clone the repository:

git clone https://github.com/longmans/coin_api_mcp.git
cd coin_api_mcp

2. Build and install using uv:

uv build
uv pip install .

Configuration

API Key Setup

The server requires a CoinMarketCap API key to function. You can provide it in two ways:

1. As an environment variable:

export COINMARKETCAP_API_KEY=your_api_key_here

2. As a command-line argument when running the server:

python -m coin_api_mcp --api-key=your_api_key_here

Claude Configuration

To configure the MCP server for Claude, add the following to your Claude settings:

"mcpServers": {
  "coin_api": {
    "command": "python",
    "args": ["-m", "coin_api_mcp"],
    "env": {
      "COINMARKETCAP_API_KEY": "your_api_key_here"
    }
  }
}

If you encounter issues, you may need to use the full path to your Python interpreter. You can find this by running which python in your terminal.

Usage Examples

Once configured, you can use the MCP server to retrieve cryptocurrency data in your conversations with Claude. Here are some example queries:

• "Show me the top 10 cryptocurrencies by market cap"
• "What's the current price of Bitcoin?"
• "Get detailed information about Ethereum"
• "List cryptocurrencies with a price between $1 and $10"

Troubleshooting

If you encounter issues:

1. Verify your CoinMarketCap API key is valid and properly configured
2. Check that the server is running correctly
3. Ensure your Claude settings are properly configured
4. Use the MCP inspector for debugging
