wcag-accessibility

MCP serverAI & models

A WCAG accessibility testing MCP for AI agents, Codex, Claude Code, and automated UI audits.

This server has no hosted endpoint yet, so ahel can't serve it. You can still add it. It stays paused until ahel can serve it.

One link, every agent. Your own credentials, stored once.

Tools it gives your agents (7)

Tool	What it does
audit_url	Load a public or local web page in headless Chromium, run axe-core, and return prioritized WCAG findings, DOM evidence, computed styles, and contrast corrections. Read-only.
audit_html	Render supplied HTML in an isolated headless browser and return WCAG findings plus evidence and suggested corrections. Use for generated UI before it is hosted. Read-only.
audit_file	Render a local .html or .htm file beneath the configured allowed root and return accessibility findings and corrections. Read-only.
check_contrast	Calculate the WCAG contrast ratio for foreground and background colors and determine whether the pair passes for the supplied text size and weight.
suggest_contrast_fix	Find the nearest black-or-white-directed foreground or background adjustment that reaches the selected WCAG contrast threshold. Returns a mathematical candidate, not an automatic edit.
explain_issue	Return implementation-focused remediation steps and the axe rule reference for a rule ID found in an audit.
get_wcag_checklist	Return every success criterion required by a WCAG 2.0, 2.1, or 2.2 A/AA/AAA profile, with W3C references, axe rule mappings, and explicit automated-partial versus manual coverage.
