check_ai_visibility

Check whether AI assistants (ChatGPT, Claude, Perplexity, Google AI) can reach, read, and cite a web page. Runs the full suite: robots.txt rules per AI crawler, a live firewall test that requests the page as GPTBot, JavaScript dependency, llms.txt, headings, structured data, and author identity. Returns a score out of 100 with a grade, a score per category, and a finding per check with why it matters and how to fix it. Use this for a whole-page verdict; use check_robots_txt_for_ai when the question is only about crawler access. Returns { ok, report: { score, grade, scoredOutOf, categories[], findings[] with why and fix, detection }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response. Free, no account, no API key.

Parameters2

url	string	required	The page to run against. A bare domain like example.com is fine; https is assumed. Must be a public URL: anything behind a login, on a private network, or on localhost is refused.
refresh	boolean	optional	Skip the 24 hour cache and run again. Costs a rate-limit slot even when a cached result exists, so leave it off unless the page has changed.

check_robots_txt_for_ai

Test a site's robots.txt against every AI crawler that matters (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Googlebot, Bingbot and the rest) and report which are allowed, which are blocked, and which rule decided it. Also runs a firewall test, because CDN-level blocks stop crawlers before robots.txt is ever read. This is the access-scoped view of check_ai_visibility. Returns { ok, report: { accessScore, crawlers[] with the rule that decided each verdict, firewall, findings[] }, cached, ageSeconds }. Limit: 10 runs per hour per IP. Allow up to 75s for a response. Free, no account, no API key.

generate_llms_txt

Generate llms.txt and llms-full.txt for a site, following the llmstxt.org convention. Inventories the site from its robots.txt, sitemaps, and homepage links, then writes an index file and a full file with page content inlined. Deterministic: no model is involved, so two runs over an unchanged site produce the same bytes. Returns the file contents ready to write to disk.

generate_json_ld

Read a page and write a schema.org JSON-LD block for it, then validate that block against the same checks a validator would run. The markup is model-written from the page's own content and should be reviewed before it is published. Returns the block ready to paste into a <script type="application/ld+json"> tag. Returns { ok, report: { detectedType, jsonLd, jsonLdString, validation: { findings[], passed }, model } }. Limit: 10 runs per hour per IP. Allow up to 75s for a response.

detect_tech_stack

Identify the platform, framework, CMS, ecommerce apps, analytics, CDN, and hosting behind a site by fingerprinting one page's HTML and response headers. One fetch, no rendering and no crawl, so it answers in about a second. A site behind bot protection is reported as blocked rather than as empty. Returns { platformName, theme, apps[], fonts[], analytics[], hosting[], renderMode, url, status, fetchedAt }. Limit: 60 runs per hour per IP. Allow up to 30s for a response. Free, no account, no API key.

    }
  },
  "required": [
    "url"
  ],
  "additionalProperties": false
}

check_favicon

Check whether a site's favicon actually works. Reads every icon declaration in the page head, then fetches each one, the web app manifest, and the implicit /favicon.ico, and identifies the real format and pixel dimensions from each file's header bytes. Catches the failures a status-code check misses: a catch-all route answering an icon path with HTML at HTTP 200, a sizes attribute that disagrees with the file, an icon served over http on an https page. Use this when a favicon is missing or blurry; use check_social_preview for the image that appears when a link is shared. Returns { hasWorkingFavicon, tabIcon, icons[] with format, dimensions, bytes and problem, manifest, themeColor, checks[] with id, status and fix, counts }. Limit: 60 runs per hour per IP. Allow up to 30s for a response. Free, no account, no API key.

capture_full_page_screenshot

Capture a full-height PNG of a page in a real headless browser, scrolling first so lazy-loaded content renders.

generate_alt_text

Find every image on a page and draft alt text for the ones that need it, using a vision model that actually looks at the image. Lists every image with the alt it has today, the suggested alt, whether it looks decorative, and why any image was skipped. Up to 10 images per run go to the model. The suggestions are drafts for a human to review. Returns { images[] with src, hadAlt, currentAlt, suggestedAlt, isDecorative, skippedReason; counts; model }. Limit: 10 runs per hour per IP.

build_utm_url

Build a campaign URL with utm parameters, normalised to one tagging convention, and report which GA4 default channel group the link will land in. Warns about the mistakes that silently break reporting: an unrecognised medium that drops traffic into Unassigned, casing that splits one source into several report rows, PII in a campaign name. Pure string work: nothing is fetched and nothing is stored. Returns { url, normalized, channel, issues[] with level, field and message }. Limit: None. The work is local and costs nothing.. Allow up to 10s for a response. Free, no account, no API key.

Parameters10

url	string	required	The destination page. Existing utm parameters on it are rewritten; any other query parameter is left alone.
source	string	optional	utm_source. Where the traffic comes from, e.g. newsletter.
medium	string	optional	utm_medium. How it gets there, e.g. email, cpc, social. This is the field GA4 reads to pick a channel.
campaign	string	optional	utm_campaign. The campaign name, e.g. spring_launch.
id	string	optional	utm_id. Optional campaign ID.
term	string	optional	utm_term. Optional paid keyword.
content	string	optional	utm_content. Optional variant, e.g. header_link.
caseRule	string	optional	How values are cased before they go in the URL. Default lower, which is what keeps one source from becoming three report rows.
spaceRule	string	optional	What happens to spaces inside a value.
stripPunctuation	boolean	optional	Drop accents and punctuation that make report rows hard to match.

hash_md5
