Use this app only for markup and public webpages the user owns or is authorized to inspect. For one live public page, use audit_public_webpage. For a bounded sitemap-first public-site audit, use audit_public_site; it audits at most eight same-origin pages per call, respects robots.txt, does not recursively follow HTML links, and never runs site-wide link checks. For pasted markup, use the focused markup tools or generate_validation_report. No tool modifies user data. HTML validation sends markup to the Nu HTML Checker hosted at validator.nu; CSS syntax, SEO, and JSON-LD checks run inside the…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

validate_html unknown never probed

Use this when raw HTML markup is supplied. Sends that markup to the Nu HTML Checker hosted at validator.nu and returns validation messages. For a live URL, use audit_public_webpage.

    }
  }
}

arguments 15 lines

validate_css unknown never probed

Use this when raw CSS source is supplied. Parses it inside the Worker and returns syntax messages without contacting an external service.

  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  }
}

arguments 15 lines

audit_seo_metadata unknown never probed

Use this for a focused SEO/accessibility-signal check of supplied HTML. It does not fetch a live webpage; use audit_public_webpage for a URL.

  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  }
}

arguments 15 lines

validate_schema_markup unknown never probed

Use this for a focused JSON-LD syntax check of supplied HTML. It parses JSON only and does not validate Schema.org vocabulary semantics.

    }
  }
}

arguments 15 lines

check_broken_links unknown never probed

Use this for a focused check of up to 20 public HTTP(S) links found in supplied HTML. It does not fetch base_url, follow redirects, or retain response bodies.

    }
  }
}

arguments 27 lines

generate_validation_report unknown never probed

Use this when HTML markup is already supplied. Combines Nu HTML validation with local CSS, SEO, accessibility-signal, and JSON-LD syntax checks. It does not fetch a webpage from base_url; use audit_public_webpage for a live URL.

audit_public_webpage unknown never probed

Use this when the user provides one live public webpage URL. Fetches one bounded static HTML response, then runs HTML validation, SEO/accessibility-signal, and JSON-LD syntax checks. It checks links only when requested and does not crawl, execute JavaScript, authenticate, or fetch linked stylesheets. Use only URLs the user owns or is authorized to inspect.

    }
  }
}

arguments 27 lines

audit_public_site unknown never probed

Use this for a bounded, sitemap-first audit of a public website the user owns or is authorized to inspect. It fetches at most 8 same-origin HTML pages per call, respects robots.txt, and returns compact page summaries plus deduplicated findings. It does not recursively follow HTML links, authenticate, execute JavaScript, fetch assets, or run site-wide link checks. Use page_offset to continue when more sitemap pages remain.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/a58acd7ba716fa47/badge.svg)](https://brick.blue/agent/a58acd7ba716fa47)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
