## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3322 tokens (~302/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability check failed: schema churn in the 14 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 2 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (11)

### `check_ai_crawler_access` (~210 tokens)

Check AI crawler access in robots.txt

Checks whether 14 AI crawlers may fetch a page. Use it when the user asks whether AI crawlers can read a website or page, for example "can AI crawlers read example.com?", "is GPTBot blocked in my robots.txt?" or "which AI bots are allowed on https://example.com/blog?". Pass the page address. Returns, for 14 AI crawlers, whether robots.txt allows the page and the rule that decided it, plus the sitemaps, the redirect chain, and the page's X-Robots-Tag header and robots meta tag. It reads robots.txt only and does not test whether a firewall blocks crawlers. Do not use it for private or local addresses, for security scans, or to collect a site's content.

Input parameters:

- `url` (string, required): Address of a public web page, for example https://example.com/pricing. A bare domain such as example.com means https. Only public http and https sites on the standard ports are checked.

Output parameters:

- `blockedCrawlers` (array): Tokens of the crawlers robots.txt blocks on this page.
- `crawlers` (array)
- `failure` (string): Why the page was not reached or read, such as a timeout or a refused redirect.

- `metaRobots` (string): The page's robots meta tag.
- `notes` (array): Plain-language caveats to pass on with the result.
- `notice` (string): As-of caveat: what the site sent to Agent Tools at that moment, not what every crawler sees.
- `reachable` (boolean): False when no page answered; failure then says why.
- `redirects` (array): Redirect chain from the address to the page.

Use it when the user asks about the meta tags, canonical tag or Open Graph social preview of a web page, for example "what will the preview look like when I share this page?", "does my homepage have a meta description and canonical tag?" or "which Open Graph tags is my page missing?". Pass the page address. Returns the title, meta description, canonical link, language, viewport, icons, Open Graph and Twitter tags, and a list of the common tags that are missing. Tags added by JavaScript are not seen. Do not use it to read a page's text or contact details, for private or local addresses, or for rankings and traffic.

Input parameters:

- `url` (string, required): Address of a public web page, for example https://example.com/pricing. A bare domain such as example.com means https. Only public http and https sites on the standard ports are checked.

Output parameters:

- `openGraph` (object)
- `page` (object)
- `reachable` (boolean): False when no page answered; failure then says why.
- `redirectCount` (integer): Number of redirects before the page.
- `source` (string): Where the data came from: the website itself.
- `status` (integer): HTTP status code of the final page.
- `twitter` (object)
- `url` (string): The address checked, after a bare domain became https.

### `trace_redirects` (~193 tokens)

Trace a 301 redirect chain

Traces the redirects and headers of a web address. Use it when the user asks where a web address redirects to, or for a 301 redirect chain, for example "why does http://example.com end up on another address?", "show the redirect chain for this link" or "does this site redirect http to https?". Pass the address. Returns each hop with its status code and target, the final address and status, whether http is upgraded to https, and the main response headers such as cache-control and strict-transport-security. At most 6 redirects are followed. Do not use it for private or local addresses, to read page content, or to scan a site for vulnerabilities.

Input parameters:

### `product_page_seo` (~263 tokens)

Check product JSON-LD and page SEO

Checks the SEO and Product data of a product page. Use it when the user asks whether one product page of an online store is set up for search, for example "is https://shop.example.com/products/blue-mug set up for search?", "does my product page have Product structured data?" or "why does Google show no price for this product?". Pass the product page address. Returns title and meta description length, h1 headings, canonical link, Open Graph tags, and the Product structured data (JSON-LD): name, brand, SKU, GTIN, MPN, price, currency, availability, variant count and rating summary, plus a list of issues found. On Shopify it adds the product handle and whether a variant parameter is in the address. Works on any store. It reads one page, skips it if robots.txt disallows it for Agent Tools, and does not run JavaScript. Do not use it for page speed, rankings or traffic, to collect prices or catalogs, or for private or local addresses.

- `url` (string): The product page address checked.

### `ai_readiness_check` (~340 tokens)

Check AI readiness of a store or page

Checks if AI agents can read and cite a store or page. Use it when the user asks whether AI agents can read an online store or cite a page, for example "does shop.example.com have an llms.txt?" or "will AI assistants cite this page?". Pass url for a page or domain for the domain files only; one is enough. Returns whether the domain has /llms.txt, /agents.md, the UCP file at /.well-known/ucp (version and services shown) and /sitemap.xml, and which of 14 AI crawlers robots.txt blocks site-wide. With a page address it also rates five citation signals (summary near the top, author credentials, Q&A format, heading structure, structured data) as pass, warn or fail with evidence and a fix. It requests at most five domain files and one page, skips what robots.txt disallows for Agent Tools, and shows what is published, not whether an agent can buy. Do not use it for private or local addresses, to read page content, or to scan for vulnerabilities.

Input parameters:

- `domain` (string): Host name of a public store or website, for example shop.example.com. Pass url or domain, not both needed. With domain only the domain files are checked (llms.txt, agents.md, UCP, sitemap, AI crawler…

- `notice` (string): As-of caveat: what the site sent to Agent Tools at that moment, not what every agent sees.
- `origin` (string): Origin the domain files were read from, after redirects.
- `page` (object)
- `platform` (string): shopify when Shopify headers were seen.
- `present` (array): Domain files that were found.

### `link_sample_check` (~235 tokens)

Check a sitemap sample for broken links

Finds broken or redirected pages in a sitemap sample. Use it when the user asks whether pages of an online store or website are broken or redirected, or for a broken link in the sitemap, for example "are any pages of shop.example.com broken?", "check my sitemap for 404s" or "do my product pages redirect?". Pass the domain. Reads the sitemap (for a sitemap index, the product, page, collection and blog sitemaps first) and checks up to 40 addresses spread across it, on that host only, returning counts by status, and for each broken, unreachable or redirected address its status and final address. It is a sample, not every page; it uses HEAD requests at low concurrency, skips addresses that robots.txt disallows for Agent Tools, and makes at most 46 requests. Do not use it for private or local addresses, to read page content, or to monitor a site over time.

Input parameters:

- `domain` (string, required): Host name of a public store or website, for example shop.example.com. If you only have a page address, pass it: only its host is used.

Output parameters:

- `domain` (string): Host checked.
- `failure` (string): Why the site or page was not reached or read, such as a timeout or a robots.txt disallow for Agent Tools.
- `issues` (array)
- `notes` (array): Plain-language caveats to pass on with the result.
- `notice` (string): As-of caveat: what the site sent to Agent Tools at that moment, not what every agent sees.
- `origin` (string): Origin the sitemap was read from, after redirects.

- `statuses` (object): Count of sampled addresses for each HTTP status code.
- `summary` (object): Counts for the sample of up to 40 addresses.

### `landing_page_check` (~252 tokens)

Check a landing page for conversion

Checks a landing page for conversion problems. Use it when the user asks how to get more sign-ups, sales or enquiries from a landing page, for example "review https://example.com/ for conversion" or "does my landing page have a clear call to action?". Pass the page address. Returns twelve checks, each with a status, evidence and a fix: the h1 and the sentence under it, the primary call to action and its repeats, whether up to five call-to-action links work, form field count, trust signals, a visible price or next step, the viewport tag, HTML size, render-blocking hints and a contact path. It reads one page, tests a few links, skips what robots.txt disallows for Agent Tools, does not run JavaScript, and returns no page copy, reviews or contact details. It is a checklist, not a conversion forecast, a speed test or a design review. Do not use it for private or local addresses, rankings or traffic.

Input parameters:

- `url` (string, required): Address of one public landing page, for example https://example.com/. A bare domain such as example.com means https. Only public http and https sites on the standard ports are checked.

Output parameters:

- `asOf` (string): When the page was read, ISO 8601 UTC.
- `blockedByRobots` (boolean): True when robots.txt disallows the page for Agent Tools, so it was not requested.

- `requestsMade` (integer): Requests made, the page and up to five call-to-action links.
- `source` (string): Where the data came from: the website itself.
- `status` (integer): HTTP status code of the final page.
- `summary` (object)
- `url` (string): The landing page address checked.

### `exposure_check` (~348 tokens)

Check the exposed surface of a site you own

Checks what a site or app the user owns leaks publicly. Use it when the user asks what an attacker could find on their own domain, host or app, for example "does my app leak a .env file?". Pass the domain, host or app page address, not a bare IP. The first call returns ownership_not_proven with a DNS TXT record or file: publish it, then call again with the same target. Then it gives exposed or clean, the top three risks with fixes, and evidence: dangling subdomains, leaked files (never their contents), masked API keys, source maps, admin paths, dev servers and default pages. It adds six legal signals with law and source (COPPA, Google Fonts, session replay, renewals, DMCA, CAN-SPAM for a passed email); not legal advice. Findings are labeled confirmed, needs verification or rejected. GET only, at most 32 fixed paths; no crawl, sign-in or port scan. Do not use it on a target the user does not own, to look up a person, user name or email, or for private or local addresses.

Input parameters:

- `email` (string): Optional: the text or HTML of one marketing email the app sends, checked for an unsubscribe link and a postal address (CAN-SPAM). It is read in memory only and never returned or kept.
- `target` (string, required): A domain, host or page address you own, such as example.com or https://app.example.com/dashboard. Not a bare IP: pass a host name that points at the server. The host is checked; a page address also n…

Output parameters:

- `target` (string): Host checked.
- `topRisks` (array)
- `tried` (array)
- `verdict` (string): ownership_not_proven: publish the record or file in publish, then call exposure_check again with the same target.

### `ai_app_check` (~369 tokens)

Check an AI-built app for leaks and open data

Checks an app made with an AI app builder (Lovable, Bolt, v0, Replit, Cursor) for leaks and launch readiness. Use it when the user asks "is my Lovable app secure?", "is my Supabase data public?", "which security headers is my app missing?" or "is my app ready to launch?". Pass the app address. For any public app it returns 8 security headers with the exact lines for the detected host (Vercel, Netlify, nginx and more), and launchList: 20 items of a 160-item launch list read from outside (renewals, mail records, security.txt, caching, legal links), each pass, fail or warn with a fix; checklist true adds the owner-only items with how to check each. The first call also returns ownership_not_proven with a DNS TXT record or file: once the owner publishes it, the next call adds exposed files (.env, .git), masked keys in the shipped JavaScript, source maps, open Supabase or Firebase data, and backend signals. GET only; database checks read status codes and row counts, never a row's data, and never write. Do not use it on an app the user does not own beyond the public checks, for private or local addresses, or to scan many sites.

Input parameters:

- `checklist` (boolean): true also returns the launch list items only the owner can check, each with how to check it (about 127 lines). Default false: only their count.
- `url` (string, required): The app's address, such as https://my-app.lovable.app/ or myapp.com. Headers and the public launch items are checked for any public app; the full check needs the owner to publish a proof token on tha…

### `submit_feedback` (~279 tokens)

Send feedback, bug report or tool request

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Input parameters:

- `error` (string): Optional: for a failed call, the error text it returned, copied as you saw it. Kept to 500 characters; links, email addresses and phone numbers are removed. Never include secrets or personal details.
- `kind` (string, required): need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.
- `message` (string, required): What you need or what broke, in plain words, at most 1000 characters. Links, email addresses and phone numbers are removed. Never include secrets or personal details.
- `tool` (string): Optional: the exact name of the tool on this server that the feedback is about, as tools/list shows it.

Output parameters:

- `note` (string)
- `reply` (string|null)
- `status` (string)
- `ticket` (string)
