Test Scrapers Inside Cursor

The `query_dom` tool allows your agent to execute CSS selectors against raw HTML strings while you write scraping logic. Hand the agent a sample page, and it tests your selectors in real time. This MCP Server stops the cycle of writing a selector, running the script, and checking the console. The agent verifies the exact text or attributes returned before writing the final code into your file.

Extract Attributes Without Browsers

Running `query_dom` means Cursor can pull specific data points out of massive markup files without spinning up full browser automation. Point the tool at the HTML and provide the target class or ID. It handles messy, production-grade DOM structures natively. The engine returns a clean JSON structure that your AI client uses to populate your mock data or test assertions.

Test Local Templates Directly

When you use `query_dom`, your editor agent reads your local HTML templates and confirms specific elements render correctly. It checks for the existence of required nodes based on your query. Setting up this MCP integration via your project mcp.json makes the tool available immediately. The agent validates your DOM structure without you ever leaving the IDE.

Setup guide

Set up HTML DOM Query Engine 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 DOM Query Engine 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 DOM Query Engine transactions." If the MCP tools are loaded correctly, Cursor will call the HTML DOM Query Engine tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "html-dom-query-engine-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }

Common questions about HTML DOM Query Engine MCP in Cursor

Add the server details to your .cursor/mcp.json file in the project root. Switch your chat to Agent mode so it can call the extraction tools.

Regular expressions break on nested or malformed tags. The engine parses the actual DOM structure, ensuring accurate extraction even when the target website changes its formatting.

Yes. It streams the parsing process rather than loading the entire document into memory at once. You can target nodes in 50MB payloads without crashing the editor.

You absolutely can. Pass the CSS selector for the anchor tags and specify the href attribute. The tool returns an array of URLs ready for your code.

The server never transmits your proprietary markup to external analytics. Your HTML strings are processed locally within the V8 isolate and purged from memory.
