AccessLumens

Overview

AccessLumens is a Model Context Protocol server that runs free WCAG accessibility checks on any web page, including localhost environments. It provides detailed fix guidance for each accessibility issue found, letting any MCP-compatible AI assistant integrate accessibility testing directly into conversations and agent workflows.

The server runs locally via the npm package @accesslumens/mcp, communicating over stdio on your machine. No authentication is required—install with npx -y @accesslumens/mcp and start checking immediately. The latest release is v0.1.3.

AccessLumens appears in the Development category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others across the ecosystem.
