🚀 Installation

# Using npm
npm install @genwave/svgmaker-mcp

# Using yarn
yarn add @genwave/svgmaker-mcp

Basic Setup

Create .env file:

SVGMAKER_API_KEY="your_api_key_here"

Start the server:

npx svgmaker-mcp

🔌 LLM Integrations

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "svgmaker": {
      "command": "npx",
      "args": ["@genwave/svgmaker-mcp"],
      "transport": "stdio",
      "env": {
        "SVGMAKER_API_KEY": "your_api_key_here"
      }
    }
  }
}

Example Claude prompt:

Generate an SVG of a minimalist mountain landscape:
<mcp>
{
  "server": "svgmaker",
  "tool": "svgmaker_generate",
  "arguments": {
    "prompt": "Minimalist mountain landscape with sun",
    "output_path": "./landscape.svg",
    "quality": "high",
    "aspectRatio": "landscape"
  }
}
</mcp>

Or configure manually:

Configure in cursor settings:

{
  "mcpServers": {
    "svgmaker": {
      "type": "local",
      "command": "npx",
      "args": ["@genwave/svgmaker-mcp"],
      "transport": "stdio",
      "env": {
        "SVGMAKER_API_KEY": "your_api_key_here"
      }
    }
  }
}

Example usage in Cursor:

Use svgmaker to edit the logo.svg file and make it more modern:
<mcp>
{
  "server": "svgmaker",
  "tool": "svgmaker_edit",
  "arguments": {
    "input_path": "./logo.svg",
    "prompt": "Make it more modern and minimalist",
    "output_path": "./modern_logo.svg",
    "quality": "high"
  }
}
</mcp>

Or configure manually:

Configure in settings.json:

{
  "servers": {
    "svgmaker": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@genwave/svgmaker-mcp"],
      "env": {
        "SVGMAKER_API_KEY": "<your_api_key>"
      }
    }
  }
}

Example usage in VS Code:

<mcp>
{
  "server": "svgmaker",
  "tool": "svgmaker_generate",
  "arguments": {
    "prompt": "Modern app icon with abstract geometric shapes",
    "output_path": "./assets/icon.svg",
    "quality": "high",
    "aspectRatio": "square"
  }
}
</mcp>

Configure in settings:

{
  "mcpServers": {
    "svgmaker": {
      "command": "npx",
      "args": ["-y", "@genwave/svgmaker-mcp"],
      "env": {
        "SVGMAKER_API_KEY": "<your_api_key>"
      }
