Tools Details

Tool: generate_image

Generate an image using Amazon Nova Canvas with text prompt.

This tool uses Amazon Nova Canvas to generate images based on a text prompt. The generated image will be saved to a file and the path will be returned.

IMPORTANT FOR ASSISTANT: Always send the current workspace directory when calling this tool! The workspace_dir parameter should be set to the directory where the user is currently working so that images are saved to a location accessible to the user.

Prompt Best Practices

An effective prompt often includes short descriptions of:

1. The subject
2. The environment
3. (optional) The position or pose of the subject
4. (optional) Lighting description
5. (optional) Camera position/framing
6. (optional) The visual style or medium ("photo", "illustration", "painting", etc.)

Do not use negation words like "no", "not", "without" in your prompt. Instead, use the negative_prompt parameter to specify what you don't want in the image.

You should always include "people, anatomy, hands, low quality, low resolution, low detail" in your negative_prompt

Example Prompts

• "realistic editorial photo of female teacher standing at a blackboard with a warm smile"
• "whimsical and ethereal soft-shaded story illustration: A woman in a large hat stands at the ship's railing looking out across the ocean"
• "drone view of a dark river winding through a stark Iceland landscape, cinematic quality"

Returns: McpImageGenerationResponse: A response containing the generated image paths.

Parameters	Type	Description
prompt	string	The text description of the image to generate (1-1024 characters)
cfg_scale	number optional	How strongly the image adheres to the prompt (1.1-10.0)
filename	string optional	The name of the file to save the image to (without extension)
height	integer optional	The height of the generated image (320-4096, divisible by 16)
negative_prompt	string optional	Text to define what not to include in the image (1-1024 characters)
number_of_images	integer optional	The number of images to generate (1-5)
quality	string optional	The quality of the generated image ("standard" or "premium")
seed	string optional	Seed for generation (0-858,993,459)
width	integer optional	The width of the generated image (320-4096, divisible by 16)
workspace_dir	string optional	The current workspace directory where the image should be saved.

    CRITICAL: Assistant must always provide the current IDE workspace directory parameter to save images to the user's current project.
