• src/tools/market.ts:137-156 (handler)

  The handler for get_market_status, which fetches market status from the growwClient and formats the response.

  server.tool(
    "get_market_status",
    "Check if NSE/BSE is currently open for trading",
    {},
    async () => {
      try {
        const statuses = await growwClient.getMarketStatus();
  
        const lines = statuses.map((s) => {
          const icon = s.status === "OPEN" ? "🟢" : s.status === "PRE_OPEN" ? "🟡" : "🔴";
          return `${icon} ${s.exchange}: ${s.status} — ${s.message}`;
        });
  
        const text = [`🏛️ MARKET STATUS`, `${"─".repeat(40)}`, ...lines, ``, `As of ${nowIST()}`].join("\n");
        return mcpText(text);
      } catch (err) {
        return mcpError(normalizeError(err));
      }
    }
  );
