Sanitize HTML inside your Cursor editor

The `sanitizeHtml_html` tool integrates directly into your active coding session to clean up raw HTML fragments. Your agent calls this tool to sanitize mock data or user inputs right inside your editor. This ensures you never commit unsafe markup to your repository. You don't need to spin up a local node server just to test your sanitization logic. The tool handles the heavy lifting in the background, giving you clean code blocks you can paste directly into your components.

Validate rich-text components during development

The `sanitizeHtml_html` tool inspects how your React or Vue components handle raw, unescaped HTML strings. Your Cursor agent runs the validation against known XSS vectors to ensure your frontend stays secure. It spots potential DOM-based vulnerabilities before you write the rendering logic. Because this runs on Vinkius, execution is incredibly fast and doesn't lag your editor. You get instant feedback on which tags were stripped and why.

Generate secure test payloads with this MCP Server

The `sanitizeHtml_html` tool helps you build test suites by generating and then cleaning malicious HTML strings. Ask your agent to write Jest or Vitest assertions using the clean output returned by the tool. It saves hours of manual test case drafting. Setting it up takes seconds by adding the server configuration to your global or project-specific configuration file. Once active, the agent gains immediate access to the sanitization logic.

Setup guide

Set up HTML XSS Sanitizer MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the HTML XSS Sanitizer MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent HTML XSS Sanitizer transactions." If the MCP tools are loaded correctly, Cursor will call the HTML XSS Sanitizer tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "html-xss-sanitizer-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}

Common questions about HTML XSS Sanitizer MCP in Cursor

Create a configuration file in your project root or global directory and add the MCP server to your list of tools. Enable agent mode in your chat panel to let your editor call the sanitization tool.

No, this MCP Server requires an internet connection to reach the secure Vinkius endpoint. However, execution happens instantly in an ephemeral sandbox, keeping latency under two milliseconds.

It strips out dangerous inline styles that can trigger script execution, like expression behaviors. It preserves safe, basic styling rules so your layout doesn't break.

It cleans user input strings at the boundary before they ever get sent to your backend. Removing script tags early prevents malicious payloads from being stored in your database tables.

It processes raw HTML strings inside an isolated, zero-trust container. No code is logged, stored, or used for training, protecting your intellectual property completely.
