Implementation Reference

• index.js:340-352 (handler)

  Handler implementation for the 'compare' tool, which iterates through provided symbols and fetches their prices.

  case 'compare': {
    const symbols = args.symbols.split(',').map(s => s.trim());
    const results = [];
    for (const sym of symbols.slice(0, 10)) {
      try {
        const p = await getCryptoPrice(sym);
        results.push(p);
      } catch (e) {
        results.push({ symbol: sym, error: e.message });
      }
    }
    return results;
  }

• index.js:300-309 (schema)

  Schema definition for the 'compare' tool, specifying input 'symbols' as a required string.

    name: 'compare',
    description: 'Compare multiple assets side by side — prices, changes, market caps.',
    inputSchema: {
      type: 'object',
      properties: {
        symbols: { type: 'string', description: 'Comma-separated symbols (e.g., "BTC,ETH,SOL")' }
      },
      required: ['symbols']
