Implementation Reference

• src/modules/finance.ts:36-45 (handler)

  The implementation of the finance_portfolio_tracker tool, which parses a comma-separated list of holdings and returns a markdown table of the portfolio.

  server.tool("finance_portfolio_tracker", "Calculate portfolio value and allocation from a list of holdings", {
    holdings: z.string().describe("Comma-separated holdings: 'BTC:0.5,ETH:10,SOL:100' or 'AAPL:50,MSFT:30'")
  }, async ({ holdings }) => {
    const items = holdings.split(",").map(h => {
      const [asset, qty] = h.trim().split(":");
      return { asset: asset.trim(), qty: parseFloat(qty) || 0 };
    });
    const rows = items.map(i => [i.asset.toUpperCase(), i.qty.toString(), "Pending lookup", "Pending"]);
    return { content: [{ type: "text", text: `**Portfolio Tracker**\n\n${mdTable(["Asset", "Qty", "Price", "Value"], rows)}\n\n*Use crypto_price or finance_stock_price to look up individual prices, then calculate total.*` }] };
  });
