Accessibility MCP Server

# CI Gate Accessibility ## Purpose Insert accessibility thresholds into CI/CD pipeline to enforce accessibility standards. ## Implementation 1. **Define Thresholds**: - Maximum number of critical violations: 0 - Maximum number of serious violations: 5 - Maximum number of moderate violations: 20 - Maximum number of unknown outcomes: 10 2. **Failure Conditions**: - Any critical violations = fail - Serious violations exceed threshold = fail - Unknown outcomes exceed threshold = fail (indicates incomplete audit) 3. **CI Integration**: - Run audit as part of CI pipeline - Parse normalised audit results - Check thresholds against summary counts - Fail build if thresholds exceeded ## Example CI Script ```typescript import { AuditExecutor } from './services/audits/audit-executor.js'; const THRESHOLDS = { critical: 0, serious: 5, moderate: 20, unknown: 10, }; const executor = new AuditExecutor(); const result = await executor.executeAxeAudit(process.env.URL); if (result.summary.by_severity.critical > THRESHOLDS.critical) { console.error('Critical violations exceed threshold'); process.exit(1); } if (result.summary.by_severity.serious > THRESHOLDS.serious) { console.error('Serious violations exceed threshold'); process.exit(1); } if (result.summary.unknown > THRESHOLDS.unknown) { console.error('Unknown outcomes exceed threshold'); process.exit(1); } ``` ## Threshold Configuration Thresholds should be: - Configurable via environment variables - Documented in CI configuration - Enforced at build time, not advisory ## Failing Example Generate a failing example by: 1. Running audit on a page with known violations 2. Checking summary counts against thresholds 3. Demonstrating CI failure output
