## Description

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.

## Prompt Examples

**Prompt:** 
```
Perform an accessibility audit on 'https://example.com' using WCAG.com.
```

**Response:** 
```
I've completed the accessibility audit for example.com! I've identified 12 issues, including 5 at the AA level related to color contrast and text scaling. Would you like the full issue list or specific remediation metadata for these findings?
```

**Prompt:** 
```
What are the requirements for WCAG guideline '1.1.1'?
```

**Response:** 
```
I've retrieved the details for WCAG 1.1.1 (Non-text Content)! It requires all non-text content to have a text alternative that serves the equivalent purpose. I can provide the implementation recommendations and success criteria for this guideline.
```

**Prompt:** 
```
List all accessibility rules used by the engine.
```

**Response:** 
```
I've retrieved the full catalog of accessibility rules! They cover standards for perceivability, operability, and robustness. I can assist you with an audit of specific rule categories to help you identify relevant markers for your project.

## Capabilities

### Check URL Compliance
Runs an immediate audit against a specific website link to identify all accessibility issues.

### Review Specific Standards
Retrieves detailed documentation and recommendations for any single WCAG guideline you name.

### List All Rulesets
Pulls the full, current catalog of accessibility rules used by the compliance engine.

### Validate API Status
Confirms that the WCAG.com service is online and ready to run audits.

## 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.

## Benefits

- Stop guessing about standards. Use `list_accessibility_rules` to 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_accessibility` to 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_details` to 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.

## How It Works

The bottom line is, you send a natural language request and get back structured data detailing specific compliance violations and how to fix them.

1. Subscribe to this MCP and provide your required WCAG.com API key.
2. Connect your agent from any compatible client like Cursor or Claude.
3. Tell your agent what you need—like 'Audit example.com for AA compliance'—and it runs the check.

## Frequently Asked Questions

**How do I audit my website using `audit_url_accessibility`?**
Just ask your agent to run an accessibility audit on your URL. The tool will check it against WCAG 2.1 and provide a detailed report listing all detected issues by level (A, AA).

The tool accepts standard WCAG identifiers like '1.4.3' or '2.1.1'. These are the official, structured codes used in compliance documentation.

**What if I need to check the service status first? Do I use `check_api_status`?**
