This MCP server extracts data like i18n translations and SVG components from TypeScript/JavaScript source code into structured JSON configuration files or individual SVG files. It helps you separate your data from your code for better maintainability and organization.
Add the MCP-data-extractor server to your MCP Client configuration:
{
"mcpServers": {
"data-extractor": {
"command": "npx",
"args": [
"-y",
"mcp-data-extractor"
],
"disabled": false,
"autoApprove": [
"extract_data",
"extract_svg"
]
}
}
}
The server provides two main extraction tools:
Use the extract_data tool to extract data (like i18n translations) from source files:
<use_mcp_tool>
<server_name>data-extractor</server_name>
<tool_name>extract_data</tool_name>
<arguments>
{
"sourcePath": "src/translations.ts",
"targetPath": "src/translations.json"
}
</arguments>
</use_mcp_tool>
Use the extract_svg tool to extract SVG components into individual files:
<use_mcp_tool>
<server_name>data-extractor</server_name>
<tool_name>extract_svg</tool_name>
<arguments>
{
"sourcePath": "src/components/icons/InspectionIcon.tsx",
"targetDir": "src/assets/icons"
}
</arguments>
</use_mcp_tool>
By default, after successful extraction, the server replaces the content of the source file with:
This helps track which files have been processed and prevents duplicate extraction.
To disable this behavior, set the DISABLE_SOURCE_REPLACEMENT environment variable:
{
"mcpServers": {
"data-extractor": {
"command": "npx",
"args": [
"-y",
"mcp-data-extractor"
],
"env": {
"DISABLE_SOURCE_REPLACEMENT": "true"
},
"disabled": false,
"autoApprove": [
"extract_data",
"extract_svg"
]
}
}
}
The data extractor supports various patterns commonly used in TypeScript/JavaScript:
export default {
welcome: "Welcome to our app",
greeting: "Hello, {name}!",
submit: "Submit form"
};
export default {
header: {
title: "Book Your Flight",
subtitle: "Find the best deals"
},
footer: {
content: [
"Please refer to {{privacyPolicyUrl}} for details",
"© {{year}} {{companyName}}"
]
}
};
export default {
faq: {
heading: "Common questions",
content: [
{
heading: "What if I need to change my flight?",
content: "You can change your flight online if:",
list: [
"You have a flexible fare type",
"Your flight is more than 24 hours away"
]
}
]
}
};
export default {
greeting: `Hello, {{username}}!`,
message: `Welcome to {{appName}}`
};
The extracted data is saved as a JSON file with dot notation for nested structures:
{
"welcome": "Welcome to our app",
"header.title": "Book Your Flight",
"footer.content.0": "Please refer to {{privacyPolicyUrl}} for details",
"footer.content.1": "© {{year}} {{companyName}}",
"faq.content.0.heading": "What if I need to change my flight?"
}
SVG components are extracted into individual .svg files with React-specific code removed:
Input (React component):
const InspectionIcon: React.FC<InspectionIconProps> = ({ title }) => (
<svg className="c-tab__icon" width="40px" id="Layer_1" data-name="Layer 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
<title>{title}</title>
<path className="cls-1" d="M18.89,12.74a3.18,3.18,0,0,1-3.24-3.11..." />
</svg>
);
Output (InspectionIcon.svg):
<svg width="40px" id="Layer_1" data-name="Layer 1" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 32 32">
<path class="cls-1" d="M18.89,12.74a3.18,3.18,0,0,1-3.24-3.11..." />
</svg>
To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "data-extractor" '{"command":"npx","args":["-y","mcp-data-extractor"],"disabled":false,"autoApprove":["extract_data","extract_svg"]}'See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:
{
"mcpServers": {
"data-extractor": {
"command": "npx",
"args": [
"-y",
"mcp-data-extractor"
],
"disabled": false,
"autoApprove": [
"extract_data",
"extract_svg"
]
}
}
}To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:
1. Find your configuration file:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.json2. Add this to your configuration file:
{
"mcpServers": {
"data-extractor": {
"command": "npx",
"args": [
"-y",
"mcp-data-extractor"
],
"disabled": false,
"autoApprove": [
"extract_data",
"extract_svg"
]
}
}
}3. Restart Claude Desktop for the changes to take effect
