Sitelemetry closes the loop between an audit and the fix. The no-signup snapshot checks a public site's security and delivery posture in eight passive checks. With a free account, the same checks, and on paid plans SEO, AI discoverability readiness, accessibility, performance and integrations, are available to your coding agent through a remote MCP server with OAuth. Every finding has evidence and a remediation; each audit output becomes one fix prompt; a re-audit shows what closed.
