batch_check
Check multiple URLs at once and get a summary table. Great for auditing an entire site or comparing competitors.
LABSCO SUMMARY
The same page can be checked alone, against a rival, or inside a list, without changing tools or vocabulary.
compare_pages and batch_check are the reason to reach for this rather than a single-URL checker — one call sets a page beside a competitor, or an entire list into one summary table. The tools also state their own depth instead of leaving you to discover it: check_seo is the detailed pass and returns improvement suggestions, while check_accessibility is described as basic and gives colour contrast hints rather than measured ratios.
What it is
A URL auditing server: one page, two pages compared, or a batch of them, checked for SEO, accessibility, performance and broken links.
What you get
- check_website, a health check covering SEO, performance, security and accessibility for a URL.
- check_seo, reporting title, meta description, headings, keywords and Open Graph tags with improvement suggestions.
- check_accessibility, covering alt texts, ARIA labels, heading hierarchy, colour contrast hints and form labels.
- find_broken_links, which crawls a page and checks its links for 404s, timeouts and redirects, capped by max_links.
- compare_pages for two URLs side by side, and batch_check for a list of URLs returned as a summary table.
Requirements
Nothing to supply — no account, no key. URLs the server can reach: every tool takes a URL rather than a file, a repository or a login.
Setup effort
One command — npx webcheck-mcp
USE CASES
01
Checking a page over before it goes live
One broad pass covers SEO, performance, security and accessibility, and the two focused tools go deeper where the broad pass flagged something.
02
Tracking down the dead links a site accumulated
Links on a page are crawled and each one checked, with max_links keeping the crawl bounded, and a batch pass turns the same check into a site-wide summary table.
03
Setting your page beside the one outranking it
Two URLs are checked in the same call and reported side by side, so the difference is in the output rather than in two separate results you have to align yourself.
