Implementation Reference

• src/tools/market.ts:16-46 (handler)

  The handler implementation for the 'get_quote' tool. It registers the tool and executes the logic to fetch quote data using growwClient.

  server.tool(
    "get_quote",
    "LTP, bid/ask, open, high, low, volume for a symbol (NSE/BSE)",
    {
      symbol: z.string().describe("Stock symbol, e.g. RELIANCE, TCS, INFY"),
      exchange: z.enum(["NSE", "BSE"]).default("NSE").describe("Exchange — NSE or BSE"),
    },
    async ({ symbol, exchange }) => {
      try {
        const sym = normalizeSymbol(symbol);
        const q = await growwClient.getQuote(sym, exchange);
        const emoji = pnlEmoji(q.change);
  
        const text = [
          `${q.symbol}.${q.exchange} ${emoji}`,
          `${q.name}`,
          `${"─".repeat(40)}`,
          `LTP: ${formatCurrencyExact(q.ltp)}  (${formatPercent(q.changePercent)}, ${pnlSign(q.change)})`,
          `Open: ${formatCurrencyExact(q.open)}  |  High: ${formatCurrencyExact(q.high)}  |  Low: ${formatCurrencyExact(q.low)}`,
          `Prev Close: ${formatCurrencyExact(q.close)}`,
          `Bid: ${formatCurrencyExact(q.bid)}  |  Ask: ${formatCurrencyExact(q.ask)}`,
          `Volume: ${formatVolume(q.volume)}  |  Market Cap: ${formatCurrency(q.marketCap)}`,
          ``,
          `As of ${nowIST()}`,
        ].join("\n");
        return mcpText(text);
      } catch (err) {
        return mcpError(normalizeError(err));
      }
    }
  );
