Function Calling

Exchange rate tools (get_exchange_rate, convert_currency) 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).

Body: { messages, model? }. Filters allowed tools by includes=exchange-rate, then executes tool_calls via MCP tools and returns the final reply.
