  2. Add to your Claude Desktop configuration:

    • On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • On Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "coingecko": {
      "command": "node",
      "args": ["/path/to/coingecko-server/build/index.js"],
      "env": {
        "COINGECKO_API_KEY": "your-api-key-here"
      }
    }
  }
}

  • get-historical-data: Get historical price, market cap, and volume data
  • get-ohlc-data: Get OHLC candlestick data
  • refresh-cache: Refresh the local coin list cache

Usage with OpenAI Function Calling

import { CoinGeckoService } from 'coingecko-server';
import OpenAI from 'openai';

const openai = new OpenAI();
const coinGeckoService = new CoinGeckoService(process.env.COINGECKO_API_KEY);

// Get function definitions
const functions = CoinGeckoService.getOpenAIFunctionDefinitions();

// Example: Get historical data
const response = await openai.chat.completions.create({
  model: "gpt-4-turbo-preview",
  messages: [{ role: "user", content: "Get Bitcoin's price history for the last week" }],
  functions: [functions[2]], // get_historical_data function
  function_call: "auto",
});

if (response.choices[0].message.function_call) {
  const args = JSON.parse(response.choices[0].message.function_call.arguments);
  const history = await coinGeckoService.getHistoricalData(
    args.id,
    args.vs_currency,
    args.from,
    args.to,
    args.interval
  );
}
