Plug Certvo into Claude, Cursor and your AI agents

Certvo speaks the Model Context Protocol over HTTP. One URL, one API key, and your agent can scan websites, explain WCAG issues, generate alt text and produce VPATs the same way it reads files.

  • 14 tools — 4 public, 10 account-bound
  • Works with Claude Code, Claude Desktop, Cursor, any MCP client
  • No SDK, no local install — just an HTTP endpoint

FAQ

Frequently Asked Questions

How is Certvo different from other accessibility tools?

Most accessibility tools either drop a JavaScript overlay on your site or generate a passive audit report. Certvo audits the underlying HTML and returns AI-generated code patches you can review and ship. We do not modify the page at runtime; we fix the source.

Does installing a script make my site fully compliant?

No, and we are transparent about that. Overlay widgets can help with some assistive features but they do not produce WCAG conformance — US courts have ruled the same. True compliance requires improving the underlying code, which is what Certvo focuses on.

How does the AI credit system work?

AI credits are consumed each time you use an AI feature: generating an explanation, a code fix, or alt text. The deterministic scan itself does not consume credits. Free accounts include 10 credits per month; paid plans include 100–500.

Can I use Certvo with any website?

Yes. Certvo works with any publicly accessible site regardless of stack — WordPress, Shopify, Webflow, Next.js, custom frameworks. The audit reads the rendered HTML, so your tech choices do not matter.

What WCAG version do you test against?

WCAG 2.1 at Levels A, AA, and AAA. Our scanner covers 60+ rules mapped to specific success criteria. EN 301 549 — the harmonised European standard — is built on top of WCAG 2.1 AA, so passing AA covers the EAA requirement too.

Will Certvo help us prepare for the European Accessibility Act?

Yes. The EAA enforces WCAG 2.1 AA via EN 301 549 from 28 June 2025 for consumer-facing services. Certvo audits against that standard, generates the code fixes, and you can produce an accessibility statement and VPAT for free using our generators.

Is my data secure?

We only analyse publicly accessible pages. Account data is encrypted in transit (TLS) and at rest. We never share scan results or AI-generated content with third parties.

Do you offer a free trial of paid features?

Yes. Sign up for a free account to scan one site with up to 100 pages and 10 AI credits a month. Upgrade only when you need more sites or credits.
