      exchange_list = "\n".join([f"- {ex.upper()}" for ex in SUPPORTED_EXCHANGES.keys()])
      return [
          types.TextContent(
              type="text",
              text=f"Supported exchanges:\n\n{exchange_list}"

      inputSchema={
          "type": "object",
          "properties": {}
      },
