What is the HTML DOM Query Engine MCP Server?
If an AI agent needs to scrape a product price from a 20,000-line e-commerce HTML page, passing the entire raw HTML to the LLM destroys its token limit and leads to hallucination. This MCP allows the LLM to pass the raw string and a CSS selector, instantly returning just the target data.
The Superpowers
- Token Saver: Offloads heavy DOM parsing to the native V8 runtime via Cheerio.
- Precision Scraping: Supports complex CSS selectors (e.g.
#main .price) and extracts specific attributes likehreforsrc.
Built-in capabilities (1)
Pass the HTML string and a CSS query (e.g. "h1", ".price", "#title"). Returns the matched text content or attributes. Parses a raw HTML string and extracts text or attributes using a CSS selector deterministically
Why Claude Code?
