Function Calling
Finance tools match the sidebar taxonomy: stocks (multi-market snapshot + TASI exchange index/company/hourly), funds (six-digit OHLCV vs NAV daily + overview stock-list; OHLCV indicators support legacy cold-start and indicatorWarmupDays), precious metals use XAUUSD on the market daily tools — same tool names as POST /api/mcp/finance.
The same tools as MCP are exposed in OpenAI-compatible format. Send the tools list to an LLM so it can return tool_calls; your gateway then executes them (e.g. via POST /api/mcp).
