Function Calling

China Fuel Price tools (get_fuel_price, get_fuel_price_by_province, calc_fuel_recharge_promo) are exposed as OpenAI-compatible functions for LLM chat.

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).
