Tracking Accessibility Compliance Is a Nightmare
Right now, checking if your site meets accessibility standards means jumping between specialized tools, downloading guidelines, and cross-referencing complex documentation. You run an audit, get 20 errors, then open another tab to figure out which WCAG guideline applies to that error, and finally copy/paste the recommendation into a spreadsheet. It's slow, prone to human error, and makes you feel like you need three PhDs just to launch a page.
With this MCP, your agent handles the entire loop. You ask it to check compliance on a URL. It runs the audit and returns not only the violation but also the specific WCAG rule that was broken—all in one conversational reply. You get actionable intelligence immediately.
Get Clarity with `list_accessibility_rules`
Manually, you'd have to hunt through dozens of technical whitepapers and documentation pages just to build a master list of standards. You wouldn’t know if the current version used 15 rules or 30.
Now, using `list_accessibility_rules` gives you an immediate, authoritative catalog of every rule in use by the WCAG auditing engine. It cuts out all the guesswork; you work off the single source of truth.
What you can do with this MCP connector
Building a site requires more than just making it look good; it has to work for everyone. This MCP connects you directly to the WCAG.com API, turning complex web compliance audits into simple conversations with your agent. You can instantly run comprehensive checks on any URL, pinpointing exactly where your code fails against official standards like WCAG 2.1.
Need to know the rules? You can pull up detailed metadata for specific guidelines or list every rule used by the auditing engine. This means you never have to manually check documentation or guess what's required for compliance. Because credential security is critical here, when you connect your API key through Vinkius, it passes through a zero-trust proxy—meaning your keys are only used in transit and never stored on disk.
You get verifiable data that lets you prove compliance without ever touching a technical validator yourself.

Who Is WCAG.com Accessibility MCP For?
This MCP is for Compliance Officers and QA engineers who are tired of manual audits across dozens of pages. It's also perfect for web designers needing instant, verifiable proof that their work meets global accessibility standards.

Performs rapid, deep-dive audits for clients, generating reports that cite specific guidelines and rulesets.
Verifies component accessibility by checking against defined WCAG standards directly from their IDE workflow.
What Changes When You Connect
- Stop guessing about standards. Use
list_accessibility_rulesto pull the full, current catalog of WCAG rules used by the engine so you know exactly what your code is being measured against. - When a client needs an audit, use
audit_url_accessibilityto get instant reports on specific URLs, identifying issues and compliance levels in minutes instead of days. - Don't waste time searching documentation. If you need details on '1.3.1 Info and Relationships,' just call
get_wcag_guideline_detailsto pull the official criteria instantly. - You can confirm your workflow is running smoothly any time by calling
check_api_status, ensuring your entire accessibility research process stays operational. - The best part? You don't have to manually track API keys. Vinkius handles the secure connection through a zero-trust proxy, so your credentials never sit on disk.
Real-World Use Cases
Pre-launch QA Check
A QA engineer needs to verify 50 pages for compliance. Instead of running 50 manual checks, they use audit_url_accessibility in a loop, feeding the results directly into their report.
Consulting Client Pitch
An accessibility consultant needs to prove expertise on color contrast issues. They call get_wcag_guideline_details for '1.4.3 Contrast' and use the precise metadata to structure their presentation.
Developer Troubleshooting
A developer is getting vague error messages. They first run list_accessibility_rules to see the exact standard the system uses, then target a specific issue with audit_url_accessibility.
Operational Monitoring
An ops lead needs to ensure their entire compliance pipeline hasn't broken overnight. They quickly run check_api_status to confirm the WCAG service is live before starting any major audits.
The Tradeoffs
Using generic audit tools
Running a basic, built-in browser accessibility checker that only flags simple issues and gives no remediation steps.
→
Use audit_url_accessibility. This MCP provides high-resolution reports tied to specific WCAG levels (A, AA) and includes detailed metadata on how to fix the problem.
Manual guideline searching
Opening multiple browser tabs or downloading PDFs just to confirm if a specific requirement was met.
→
Call get_wcag_guideline_details. It pulls the authoritative source data instantly, giving you the exact criteria needed for compliance.
Assuming API uptime
Starting an entire audit workflow and only realizing halfway through that the underlying service is down.
→
Always call check_api_status first. It confirms the WCAG service is fully operational before you invest time running a complex, multi-URL audit.
When It Fits, When It Doesn't
Use this MCP if your job requires verifying compliance against published, industry-standard rules (WCAG 2.1). You need verifiable data on why something fails, not just that it failed. The core strength here is the depth of the audit: you can pinpoint issues using audit_url_accessibility and then immediately reference the official rule via get_wcag_guideline_details. Don't use this if your goal is simple keyword tagging or general content review; you need a true compliance checker. If all you want are broad industry best practices without URL testing, there might be other resources, but for hard-data auditing and technical validation, this MCP is the definitive choice.
