• src/modules/crypto.ts:17-27 (handler)

  The handler for the 'crypto_trending' tool, which fetches data from the CoinGecko API and formats it into a Markdown table.

  server.tool("crypto_trending", "Get top 7 trending cryptocurrencies on CoinGecko", {}, async () => {
    const data = await safeFetch("https://api.coingecko.com/api/v3/search/trending");
    const coins = data.coins.slice(0, 7);
    const rows = coins.map((c: any, i: number) => [
      `${i + 1}`, c.item.name, c.item.symbol.toUpperCase(),
      `#${c.item.market_cap_rank || "N/A"}`,
      formatCurrency(c.item.data?.price || 0),
      formatPercent(c.item.data?.price_change_percentage_24h?.usd || 0)
    ]);
    return { content: [{ type: "text", text: `**Trending Coins**\n${mdTable(["#", "Name", "Symbol", "Rank", "Price", "24h"], rows)}` }] };
  });
