image2svg-mcp 1.0.1

MCP server that converts raster images (PNG/JPG/WEBP) to SVG vector format

image2svg-mcp

An MCP server that converts raster images (PNG, JPG, WEBP) to scalable SVG vector graphics.

Features

• Accepts images as base64-encoded data or URL
• Supports PNG, JPG, JPEG, WEBP, TIFF, and other common raster formats
• Full control over vectorization parameters (color precision, speckle filtering, tracing mode, etc.)
• Handles data:image/...;base64, URI prefixes automatically
• Streams URL downloads with a 5 MB size limit
• Optional file:// URL support for local images (opt-in via --allow-local-files-path)

Usage

Claude Code & Claude Desktop

Add to your settings.json:

{
  "mcpServers": {
    "image2svg": {
      "command": "uvx",
      "args": ["image2svg-mcp"]
    }
  }
}

for Claude Code add using command line:

claude mcp add image2svg --scope user -- uvx image2svg-mcp

with access to local files:

claude mcp add image2svg --scope user -- uvx image2svg-mcp --allow-local-files-path /home/user/images

Docker

Run as an HTTP server:

docker run -p 8000:8000 ghcr.io/botmonster/image2svg-mcp

With local file access:

docker run -p 8000:8000 -v /home/user/images:/images ghcr.io/botmonster/image2svg-mcp --allow-local-files-path /images
claude mcp add image2svg --transport http --scope user http://localhost:8000/mcp

This enables prompts like:

Convert this local file to SVG: file://logo.png

Only files inside the specified directory (and its subdirectories) are accessible. Paths are normalized to prevent directory traversal. Without this flag, file:// URLs are rejected.

Example Prompts

Here are some examples of what you can tell an LLM to do with this tool:

1. Simple image-to-SVG conversion

Generate an image of a sunset over mountains, then convert it to SVG.

The LLM will generate a raster image and then use the convert_image_to_svg tool with default settings to produce a clean vector version.

2. Fine-tuned conversion with specific parameters

Create a logo with a blue circle and a white star inside it. Now convert it to SVG using binary colormode for crisp edges and set filter_speckle to 10 to remove noise.

This uses colormode: "binary" for black/white line art style output, which works great for logos and icons. The higher filter_speckle value removes small artifacts.

3. Convert from URL with minimalist style

Convert this image to a simplified SVG with low color precision for a minimalist poster look: https://example.com/photo.png

Using color_precision: 3 reduces the number of colors dramatically, producing an artistic posterized vector effect. Great for stylized illustrations.

4. Convert a base64 image directly

Convert this base64 image to SVG: iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAAO0lEQVR4nGP8z8Dwn4EIwESMIqwKGRn+MzBisYQJXRE2NopCbKYgi5Huxv8MjBiSyGJMuCTQNTJSPRwBCjYOD5JU5rIAAAAASUVORK5CYII=

This is a 10x10 red square with a blue circle in the middle. Useful for testing the tool with inline image data — no URL needed.

Tool Parameters

Parameter	Type	Default	Range	Description
image_base64	string	-	-	Base64-encoded image data. Provide this OR image_url.
image_url	string	-	-	URL to fetch the image from (http://, https://, or file:// when enabled). Provide this OR image_base64.
colormode	string	"color"	color, binary	Full color or black/white line art
mode	string	"spline"	spline, polygon, none	Tracing mode: smooth curves, straight edges, or pixel-perfect
filter_speckle	int	4	0-128	Remove speckles of N pixels or fewer
color_precision	int	6	1-12	Color quantization bits. Lower = fewer colors, simpler SVG
layer_difference	int	16	0-128	Color difference for merging layers
corner_threshold	int	60	0-180	Angle threshold for corner detection (degrees)
length_threshold	float	4.0	3.5-10.0	Minimum path segment length
splice_threshold	int	45	0-180	Angle threshold for splicing splines
path_precision	int	8	1-12	Decimal precision for SVG coordinates
hierarchical	string	"stacked"	stacked, cutout	Layer arrangement mode
max_iterations	int	10	1-100	Max curve fitting iterations
