Target DOM Nodes in Claude Desktop

The `query_dom` tool lets your agent parse raw HTML strings using standard CSS selectors. Paste a 50MB HTML payload into the chat, and the tool extracts the exact text nodes or attributes you specify. This MCP Server completely bypasses the memory overhead of headless browsers. Your client reads the document stream, applies the selector, and returns only the matched data back to your conversation.

Extract Attributes Fast

Calling `query_dom` gives Claude the ability to pull specific attributes like href or src from heavily nested markup. Tell your agent to grab all the link targets from a scraped page, and it executes the query and returns the array. You avoid writing custom regex for malformed HTML. The engine handles broken tags natively and outputs clean JSON arrays containing your requested elements.

Memory-Efficient Local Parsing

Because `query_dom` processes the DOM tree directly, your local machine won't crash when Claude Desktop handles gigabyte-scale logs or exports. It allocates memory only for the matched CSS selectors. Connect this MCP integration via your local configuration file and start querying immediately. The agent maps the results straight into whatever analysis or summary you asked for.
