mcp-usage
This skill should be used whenever the Axe MCP Server tools (analyze, remediate) are available and the task involves accessibility, a11y, WCAG conformance, keyboard navigation, modal dialogs, accessible names and roles, or "fix accessibility issues" on web UI. It teaches the correct analyze -> remediate -> verify workflow, guided tests (keyboard, interactive elements, modal) through analyze's igtTools, the exact field mapping between the tools, batching rules, and credit-aware usage. Trigger phrases include "check accessibility", "scan for a11y issues", "fix accessibility violations", "make this accessible", "axe scan", "test keyboard accessibility", "check tab order", "check focus traps", "test my modal", "check the dialog's focus handling", "audit accessible names and roles", "check my custom controls".

Using the Axe MCP Server effectively Deque's Axe MCP Server exposes two tools: analyze — scan a URL with the real Axe DevTools engine (axe-core rules plus Advanced Rules). On request, it also runs guided tests against the same page in the same call through its igtTools parameter: keyboard, interactive-elements, and modal. remediate — get AI fix guidance for a batch of issues, from the axe scan and guided tests alike. Some servers also list a standalone igt tool titled "IGT (Deprecated)". It is kept only for backward compatibility. Do not call it — pass igtTools to analyze instead. The tools may appear under a client-specific prefix (for example mcpaxe-mcp-serveranalyze in Claude Code, mcpaxe-mcp-serveranalyze in Copilot). Match whatever naming the host client uses; the behavior is identical. When this guidance and the server disagree, the server wins The shapes and parameters described here are those of server 1.6.0.
