The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_page Compare raw HTML with rendered DOM ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | Full http(s) URL of the page to analyse |
No output schema declared.
No examples provided.
check_ai_bots Check AI bot access ~83
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).
