What your AI can do with Web Validator by DigestSEO
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “validate_html”: Use this when raw HTML markup is supplied. Sends that markup to the Nu HTML Checker hosted at validator.nu and returns validation messages.”
“Use “validate_css”: Use this when raw CSS source is supplied. Parses it inside the Worker and returns syntax messages without contacting an external service.”
“Use “audit_seo_metadata”: 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.”
“Use “validate_schema_markup”: Use this for a focused JSON-LD syntax check of supplied HTML. It parses JSON only and does not validate Schema.org vocabulary semantics.”
How secure is the Web Validator by DigestSEO MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Web Validator by DigestSEO holds up.
Official endpoint
Operated by Web Validator by DigestSEO (digestseo.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Web Validator by DigestSEO adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
