Implementation Reference

• src/tools/watchlist.ts:20-41 (handler)

  The handler function for get_watchlist that fetches the watchlist data and formats it for output.

  async () => {
    try {
      const items = await growwClient.getWatchlist();
      if (items.length === 0) return mcpText("📭 Watchlist is empty. Add symbols to track them.");
  
      const lines = items.map((w) => {
        const emoji = pnlEmoji(w.change);
        return `${emoji} ${w.symbol.padEnd(12)} ${formatCurrencyExact(w.ltp).padStart(12)}  ${pnlSign(w.change)} (${formatPercent(w.changePercent)})  ${w.name}`;
      });
  
      const text = [
        `👁️ WATCHLIST (${items.length} symbols)`,
        `${"─".repeat(70)}`,
        ...lines,
        ``,
        `As of ${nowIST()}`,
      ].join("\n");
      return mcpText(text);
    } catch (err) {
      return mcpError(normalizeError(err));
    }
  }

• src/tools/watchlist.ts:16-42 (registration)

  Registration of the get_watchlist tool using server.tool.

  server.tool(

    async () => {
      try {
        const items = await growwClient.getWatchlist();
        if (items.length === 0) return mcpText("📭 Watchlist is empty. Add symbols to track them.");
  
        const lines = items.map((w) => {
          const emoji = pnlEmoji(w.change);
          return `${emoji} ${w.symbol.padEnd(12)} ${formatCurrencyExact(w.ltp).padStart(12)}  ${pnlSign(w.change)} (${formatPercent(w.changePercent)})  ${w.name}`;
        });
  
        const text = [

        ].join("\n");
        return mcpText(text);
      } catch (err) {
