Tools#

generate_image_gemini#

Generates an image using the Gemini Image API. Supported Models (aliases are internal): The model parameter allows selection between available image generation models. - "gemini-2.5-flash-image" (recommended default for stable, fast response). - "gemini-3-pro-image-preview". - "gemini-3-flash"

text

        Aliases for these models are 'nano-banana 2.5' and 'nano-banana 3 Pro' respectively.
        Please use 'gemini-2.5-flash-image' unless the user specifically requests the Gemini 3 model.

    Args:
        model: The image generation model to use (see supported models above). Defaults to "gemini-2.5-flash-image". Supports: 'gemini-3-flash', 'gemini-3-pro-image-preview', 'gemini-2.5-flash-image'
        prompt: A detailed text description for the image to be generated.
        image_name: The filename for the output image, can be a relative path. Defaults to "gemini_output_images.png".
        output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations.
        aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'). Defaults to '16:9'.
        image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'). Defaults to '1K'.

    Return:
        Dict: Result dictionary containing image path, message, and success status.
        output_result["image_path"]: str
        output_result["image_url"]: str
        output_result["message"]: str
        output_result["success"]: bool

Parameters:

• model (string, optional):
• prompt (string, optional):
• image_name (string, optional):
• output_folder (object, optional):
• aspect_ratio (string, optional):
• image_size (string, optional):

generate_image_nano_banana#

Generate Image With Nano Banana

text

    Args:
        model: The image generation model to use. Defaults to "gemini-2.5-flash-image". Supported Models such as follows Google Gemini Doc, such as 'gemini-3-flash', "gemini-3-pro-image-preview", "gemini-2.5-flash-image", note that nano-banana is the alias name of the Gemini Image Model. Nano banana 3 Pro refers to Gemini 3 pro preview, and Nono Banana 2.5 refers to Gemini 2.5. Unless specified by user to use Gemini 3 model preview, general 'Neno Banana' image models, please use 'gemini-2.5-flash-image' for more stable and fast response.
        prompt: A detailed text description for the image to be generated.
        image_name: The filename for the output image, can be a relative path, such as "./new_gemini_image.png", etc. Defaults to "gemini_output_images.png".
        output_folder: The optional absolute folder path provided by the user where the image will be saved. Do not use default server locations.
        aspect_ratio: The aspect ratio of the generated image (e.g., '16:9', '1:1', '4:3'), defaults to '16:9'.
        image_size: The size/resolution of the generated image (e.g., '1K', '2K', '4K'), defaults to '1K'.

    Return:
        Dict:  output_result is the result dict of MCP returned
        output_result["image_path"] = full_path: str
        output_result["message"] = output_message: str
        output_result["success"] = success: bool

Parameters:

• model (string, optional):
• prompt (string, optional):
• image_name (string, optional):
• output_folder (object, optional):
• aspect_ratio (string, optional):
• image_size (string, optional):
