`bash
npm install -g mcp-svg-converter
mcp-svg-converter /path/to/allowed/directory
`

#### From Source

##### Prerequisites

- Node.js 16 or higher
- npm or yarn

##### Installation Steps

1. Clone this repository
`bash
git clone https://github.com/surferdot/mcp-svg-converter.git
cd mcp-svg-converter
`

2. Install dependencies
`bash
npm install
`

3. Build the project
`bash
npm run build
`

$3

#### As a standalone server

Run the server by specifying one or more allowed directories where the converted images can be saved:

`bash
node build/index.js /path/to/allowed/directory1 /path/to/allowed/directory2
`

#### With Claude Desktop

1. Download and install Claude Desktop
2. Create or confirm you have access to an output directory:
`bash
# macOS/Linux
mkdir -p ~/Desktop/svg-output

# Windows
mkdir "%USERPROFILE%\Desktop\svg-output"
`

3. Configure Claude Desktop by editing the configuration file:
- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json

4. Open the Claude app, click on the Claude menu in your system menu bar and select "Settings..."
5. Click on "Developer" in the left sidebar
6. Click "Edit Config" to open the configuration file

7. Add this server configuration:

##### Using npm package with npx (recommended)

`json
{
"mcpServers": {
"svg-converter": {
"command": "npx",
"args": [
"mcp-svg-converter",
"/absolute/path/to/output/directory"
]
}
}
}
`

##### Using global installation

If you've installed the package globally:

`json
{
"mcpServers": {
"svg-converter": {
"command": "mcp-svg-converter",
"args": [
"/absolute/path/to/output/directory"
]
}
}
}
`

##### Using local build

If you've built from source:

`json
{
"mcpServers": {
"svg-converter": {
"command": "node",
"args": [
"/absolute/path/to/mcp-svg-converter/build/index.js",
"/absolute/path/to/output/directory"
]
}
}
}
`

8. Save the file and restart Claude Desktop

#### Verifying the Setup

When Claude Desktop restarts, if configured correctly:

1. You should see a hammer icon at the bottom right of the input box indicating MCP tools are available.
2. Clicking the hammer icon should show the svg-to-png and svg-to-jpg tools.

$3

#### Example 1: Converting a Simple SVG to PNG

In Claude Desktop, send a message like:

`
Please convert this SVG to PNG and save it to my output directory:





SVG Example

`

#### Example 2: High-Quality JPG Conversion

`
Please convert this SVG to a JPG with 95% quality and 2x scaling:






`

$3

#### svg-to-png

Converts SVG code to a high-quality PNG image with transparency support.

Parameters:
- svgCode (string, required): The SVG code to convert
- outputPath (string, required): Path where the PNG file should be saved
- backgroundColor (string, optional): Background color (default: transparent)
- scale (number, optional): Scale factor for higher resolution (default: 1)

#### svg-to-jpg

Converts SVG code to a high-quality JPG image.

Parameters:
- svgCode (string, required): The SVG code to convert
- outputPath (string, required): Path where the JPG file should be saved
- backgroundColor (string, optional): Background color (default: white)
- quality (number, optional): JPEG quality from 1-100 (default: 90)
- scale (number, optional): Scale factor for higher resolution (default: 1)

$3

#### Specifying Multiple Output Directories

You can specify multiple allowed output directories for more flexible file saving:

`json
{
"mcpServers": {
"svg-converter": {
"command": "npx",
"args": [
"mcp-svg-converter",
"/Users/yourusername/Desktop/svg-output",
"/Users/yourusername/Documents/svg-images",
"/Users/yourusername/Downloads"
]
}
}
}
`

#### Using Custom Output Filenames

Specify detailed file paths in your request:

`
Please convert this SVG to PNG, and save it as "colorful_shapes.png" in my output directory.


`

#### Automatic Path Redirection

If you request saving to a non-allowed directory, the converter automatically redirects to an allowed directory and informs you of the actual save location.

$3

#### Claude Doesn't Show MCP Tools Icon
1. Verify the configuration file has correct JSON syntax
2. Ensure all paths are absolute paths
3. Make sure output directories exist and are writable
4. Completely exit and restart Claude Desktop
5. Check Claude logs:
- macOS: ~/Library/Logs/Claude/mcp*.log
- Windows: %APPDATA%\Claude\logs\mcp*.log

#### Tool Execution Fails
1. Ensure mcp-svg-converter is correctly installed
2. Check output directory permissions
3. Verify the SVG code is valid
4. Check Claude logs for detailed error messages

#### "Command Not Found" Error
1. Ensure mcp-svg-converter is globally installed or correctly reference npx
2. Confirm npm's global bin directory is in your PATH
3. Try using full paths in configuration

$3

You can use the MCP Inspector to debug and test the server directly:

`bash
npx @modelcontextprotocol/inspector npx mcp-svg-converter /path/to/allowed/directory
`

This opens an interactive interface where you can test all available tools without going through Claude Desktop.

$3

- The server will only write files to the directories specified when starting the server
- If a user attempts to save to a non-allowed directory, the file will be automatically redirected to an allowed directory
- Path traversal attacks are prevented by proper path validation

$3

#### Claude 没有显示 MCP 工具图标
1. 确认配置文件格式正确（JSON 语法）
2. 检查所有路径是否为绝对路径
3. 确保输出目录存在且可写
4. 完全退出并重启 Claude Desktop
5. 检查 Claude 日志：
- macOS: ~/Library/Logs/Claude/mcp*.log

2. 确认 npm 的全局 bin 目录在系统 PATH 中
3. 尝试在配置中使用完整路径

$3

您可以使用 MCP Inspector 直接调试和测试服务器：

`bash
npx @modelcontextprotocol/inspector npx mcp-svg-converter /path/to/allowed/directory
``

这将打开一个交互式界面，你可以在其中测试所有可用工具，而无需通过 Claude Desktop。

$3

- 服务器只会将文件写入启动服务器时指定的目录
- 如果用户尝试保存到非允许目录，文件将自动重定向到允许的目录
- 通过适当的路径验证防止路径遍历攻击
