The Website Specification bronze

mcp.specification.website

“Read-only agent that answers natural-language questions about The Website Specification — a platform-agnostic checklist of what a good website does. Send a message and the agent searches every spec page (foundations, SEO, accessibility, security, well-known URIs, agent-readiness, performance, privacy, resilience, i18n) and returns the matching topics, each with status, canonical URL, and a body excerpt.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of mcp.specification.website controls every word below.

Search the spec

Free-text search across every spec page. Returns ranked results with title, status, category, canonical URL, and a body excerpt.

searchdiscoveryweb-standards
Examples it gives
  • what is content security policy
  • how do I implement llms.txt
  • required SEO topics

Fetch a spec topic

Examples it gives
  • topic:content-security-policy
  • topic:meta-robots

Audit a website against the spec

Pair this agent with a browsing agent: ask it for the relevant required and recommended topics for a category (security, seo, accessibility, performance, privacy, i18n, resilience, agent-readiness, well-known, foundations) and the audit plan falls out.
