Perplexity

Automate URL accessibility auditing.

The `audit_url_accessibility` tool lets the entire team run a comprehensive WCAG audit on any target URL. This is critical for maintaining consistent compliance markers across all features. Team members can now ask Copilot Chat to perform this audit and use the resulting data report directly in their commit messages or pull request descriptions.

Verify service connectivity via MCP Server.

You can run `check_api_status` to confirm that the WCAG.com service is up before any developer starts coding against it. This shared configuration prevents accidental build failures across the whole team. It’s a simple, reliable check that ensures everyone on the engineering team has access to necessary external services.

Retrieve guideline details for compliance.

Use `get_wcag_guideline_details` to pull official metadata and recommendations for specific WCAG guidelines. This centralizes knowledge, meaning developers don't have to hunt through documentation. Copilot Chat uses this detailed info to generate code snippets that meet the highest level of accessibility standards.
