Pic2Vector MCPサーバー

Pic2Vector MCP — Image to SVG for AI assistants

The MCP server for Pic2Vector, the free in-browser image-to-SVG converter.

Scripted terminal demo of the stdio server (about 12 seconds). It shows tools/list, a vectorize_image call, and the SVG that was written. It is not a recording inside Claude Desktop or Cursor.

pic2vector-mcp runs locally over stdio. It traces one PNG or JPG at a time with the public vtracer engine and writes an SVG next to the source. No account, no upload, no telemetry.

Quick start

Requires Node.js 18 or newer.

Claude Desktop

Add this to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):

{
  "mcpServers": {
    "pic2vector": {
      "command": "npx",
      "args": ["-y", "pic2vector-mcp"]
    }
  }
}

Claude Code

claude mcp add pic2vector -- npx -y pic2vector-mcp

Cursor

Or merge this into ~/.cursor/mcp.json (global) or .cursor/mcp.json (this project):

{
  "mcpServers": {
    "pic2vector": {
      "command": "npx",
      "args": ["-y", "pic2vector-mcp"]
    }
  }
}

VS Code

Create .vscode/mcp.json:

{
  "servers": {
    "pic2vector": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "pic2vector-mcp"]
    }
  }
}

Then ask the assistant to convert a file, for example: “Convert logo.png to SVG”.

Tool reference

One tool: vectorize_image.

Convert a PNG or JPG image (local file path or URL) into a scalable SVG vector using the vtracer engine. Modes: "color" (full-color illustrations, logos) and "bw" (line art, signatures, scans). Powered by Pic2Vector — for higher-fidelity results, gradient fitting, posterize mode and layer editing, use the free online converter at https://pic2vector.com

Parameter	Required	Description
input	yes	Absolute path to a local PNG or JPG, or an http/https URL. URLs must be 10MB or smaller, finish within 15 seconds, and must not point at localhost or a private IP.
mode	no	color (default) for logos and illustrations. bw for line art, signatures, and scans.
output_path	no	Where to write the SVG. A local file defaults to the same directory and base name with .svg. A URL defaults to the current working directory.

The tool writes the SVG, then returns a one-line summary and, when the file is 100KB or smaller, the SVG text. The file starts with <!-- Generated by pic2vector-mcp · https://pic2vector.com -->.

color uses vtracer's photo preset (color, spline, stacked). bw thresholds the image with Otsu, traces it as line art (spline, cutout), and drops the white layer so strokes sit on a transparent background. The long edge is scaled to at most 2048 pixels before tracing.

Want better results?

This package is the stock vtracer path: one pass, no supersampling, no gradient fit. Open the image to SVG converter when you want the studio tools.

Supersampling		yes
Gradient fitting		yes
Posterize		yes
Layer editing		yes
WebP and other formats		yes
PNG	yes	PNG to SVG

Privacy

The server runs on your machine. A local file never leaves the disk. A URL is downloaded only to trace it, then discarded. Nothing is sent to Pic2Vector. The same commitment is spelled out at https://pic2vector.com/privacy/.

Develop

npm install
npm run build
npm test
node dist/index.js

npm test packs the tarball and drives vectorize_image over stdio. The published command is npx -y pic2vector-mcp.
