SVG Optimizer MCP Server

A Model Context Protocol (MCP) server that provides SVG optimization capabilities using SVGO. This server allows AI assistants and other MCP clients to optimize SVG files to reduce their file size while maintaining visual quality.

Features

• Simple SVG Optimization: Optimize SVG files using SVGO's proven default settings
• File Size Analytics: Get detailed statistics about optimization results
• Error Handling: Clear error messages for invalid SVG content
• Zero Configuration: Works out of the box with sensible defaults
• NPX Compatible: Can be run directly via npx without installation

Installation

Add this configuration to your MCP client's mcp.json:

{
  "mcpServers": {
    "svg-optimizer": {
      "command": "npx",
      "args": ["svgo-mcp"]
    }
  }
}

Usage

The server provides a single tool: optimize_svg

Tool: optimize_svg

Optimizes an SVG file using SVGO with default settings.

Parameters:

• content (required): The SVG file content as a string
• filename (optional): Filename for context and reporting

Example Usage:

{
  "name": "optimize_svg",
  "arguments": {
    "content": "<svg ... /></svg>",
    "filename": "icon.svg"
  }
}

Response:

{
  "success": true,
  "filename": "icon.svg",
  "optimization": {
    "originalSize": 85,
    "optimizedSize": 65,
    "savings": 20,
    "savingsPercent": "23.5%",
    "compressionRatio": "0.765"
  },
  "optimizedContent": "<svg ... /></svg>"
}

Response Format

The server returns a JSON object with the following structure:

• success: Boolean indicating if optimization was successful
• filename: The provided filename or "untitled.svg" if not specified
• optimization: Object containing size statistics
  • originalSize: Original file size in bytes
  • optimizedSize: Optimized file size in bytes
  • savings: Bytes saved through optimization
  • savingsPercent: Percentage of size reduction
  • compressionRatio: Ratio of optimized size to original size
• optimizedContent: The optimized SVG content

Use Cases

• Web Development: Optimize SVG icons and graphics for faster loading
• Asset Processing: Batch optimize SVG files in build pipelines
• Content Management: Reduce storage requirements for SVG assets
• Performance Optimization: Minimize bandwidth usage for SVG delivery
