## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-21 (score 71)

First indexed and scored.

## MCP tools (2)

### `analyze_page` (~109 tokens)

Compare raw HTML with rendered DOM

Loads the URL in Chrome and compares what a crawler that does not run JavaScript receives (the raw HTML) with the rendered page, using the Unrendered extension's analysis. Returns the share of the main content present in the raw HTML, words only added by JavaScript, the text blocks missing from the raw HTML, head and JSON-LD field differences, challenge or error gates, and a not_checked list.

Input parameters:

- `url` (string, required): Full http(s) URL of the page to analyse

### `check_ai_bots` (~83 tokens)

Check AI bot access

For each AI bot the extension knows (GPTBot, ClaudeBot, PerplexityBot and others), returns the robots.txt verdict for the URL and what the server answers when requested with that bot's published user-agent (same page, different page, blocked, challenged, redirected).

Input parameters:

- `url` (string, required): Full http(s) URL of the page to analyse
