The SVG to PNG MCP Server is a tool server based on the Model Context Protocol (MCP) designed to convert SVG code to PNG images. It supports integration with other MCP clients and offers two methods for conversion: CairoSVG for simplicity and speed, and Inkscape for full SVG feature support.

SVG to PNG MCP Server

Features

  • Converts SVG code to PNG images
  • Supports specifying working directory
  • Based on the MCP protocol, compatible with other MCP clients

SVG to PNG Conversion Methods

  1. CairoSVG Method (currently in use)

    • Fast conversion speed
    • Minimal dependencies, easy to install
    • Suitable for simple SVG graphics
    • Limitations: special handling for Chinese fonts, limited complex SVG feature support

  2. Inkscape Method (alternative)

    • Full SVG feature support
    • Better font rendering
    • More accurate conversion
    • Limitations: requires Inkscape installation, slower conversion speed

Installation

  1. Create and activate a virtual environment.
  2. Install dependencies from requirements.txt.

Configuration

  1. Copy example configuration file and edit it using absolute paths for both the command and arguments.

Usage

Run the test client to generate a PNG image. Ensure the virtual environment is activated and correct absolute paths are used in servers_config.json.
