🛠️ Available Tools

svgmaker_generate

Generate SVG images from text prompts. Supports style parameters for fine-grained control over the output.

{
  "prompt": "A minimalist mountain landscape with sun",
  "output_path": "/path/to/landscape.svg",
  "quality": "medium",
  "style": "flat",
  "color_mode": "few_colors",
  "composition": "full_scene",
  "background": "transparent"
}

Raster mode — set raster: true to skip vectorization and get a PNG instead of an SVG. Use a .png extension for output_path. Cannot be combined with storage (raster results are temporary).

{
  "prompt": "A minimalist mountain landscape with sun",
  "output_path": "/path/to/landscape.png",
  "quality": "medium",
  "raster": true
}

Parameter	Type	Description
raster	boolean	When true, returns a raster PNG instead of SVG (skips vectorization). Use a .png output path. Cannot be used with storage.
storage	boolean	When true, stores the generated image permanently in cloud storage. Cannot be used with raster. Defaults to true when raster is not set.

Style parameters (generate & edit)

All parameters below are optional and shared by svgmaker_generate and svgmaker_edit. Only specify the ones the user explicitly requests.

Parameter	Values	Default	Description
quality	low, medium, high	medium	Detail level vs. speed. high forces a square aspect ratio.
aspectRatio	square, portrait, landscape	auto (by quality)	Output shape. Ignored when quality is high (forced square).
background	auto, transparent, opaque	auto	Background style. transparent is good for overlays.
style	flat, line_art, engraving, linocut, silhouette, isometric, cartoon, ghibli	—	Art style.
color_mode	full_color, monochrome, few_colors	full_color	Color scheme.
image_complexity	icon, illustration, scene	—	Level of detail in the composition.
composition	centered_object, repeating_pattern, full_scene, objects_in_grid	—	Layout arrangement.
text_style	only_title, embedded_text	—	How text is handled in the design.

svgmaker_edit

Edit existing SVGs or images with natural language. Supports the same style parameters as generate. Accepts a local file path or generation ID (works for both your own generations and public gallery items).

{
  "input_path": "/path/to/input.svg",
  "prompt": "Add a gradient background and make it more vibrant",
  "output_path": "/path/to/enhanced.svg",
  "quality": "high",
  "style": "cartoon",
  "background": "opaque"
}

Or edit directly from a generation ID (works for both generations and gallery items):

{
  "generation_id": "gen_abc123",
  "prompt": "Make the background blue",
  "output_path": "/path/to/edited.svg"
}

Raster mode — like generate, set raster: true to get a PNG instead of an SVG. Use a .png extension for output_path. Cannot be combined with storage.

{
  "input_path": "/path/to/input.svg",
  "prompt": "Make it more vibrant",
  "output_path": "/path/to/edited.png",
  "raster": true
}

Parameter	Type	Description
raster	boolean	When true, returns a raster PNG instead of SVG (skips vectorization). Use a .png output path. Cannot be used with storage.
storage	boolean	When true, stores the edited image permanently in cloud storage. Cannot be used with raster. Defaults to true when raster is not set.
