Axcess

What is Axcess?

Axcess is a paid MCP server that evaluates typography for accessibility issues beyond what automated scanners catch. It uses x402 micropayments (USDC on Base mainnet) and is designed for developers, designers, and accessibility auditors using MCP clients like Claude, Cursor, or AI agents.

How to use Axcess?

Connect as an MCP client: for Claude Desktop or Cursor, add to claude_desktop_config.json with "command": "npx" and "args": ["mcp-remote", "https://axcess-mcp-server.fly.dev/mcp"]. For programmatic use, install @x402/fetch and call the evaluate_typography tool. Use list_capabilities (free) to explore available tools; each evaluate_typography evaluation costs $0.05 USDC.

FAQ from Axcess

What does Axcess catch that automated scanners miss?

Automated tools catch roughly 30% of WCAG failures and almost none of the design-judgment failures. Axcess evaluates contrast with font-weight context, line-height adequacy for dyslexia, and dozens of design-craft rules from Bringhurst and Lupton.

How much does Axcess cost?

list_capabilities is free. evaluate_typography costs $0.05 USDC per call, paid via the x402 protocol on Base mainnet (eip155:8453). An evaluate_accessibility tool ($0.10) is coming soon.

What are the runtime requirements?

Self-hosted locally: Node.js 18+, a USDC wallet on Base, and a free CDP API key. For hosted use, just configure your MCP client with the server URL. No additional dependencies are required on the client side.

Where does my data go?

Data is sent to the Axcess server for evaluation; the README does not describe retention or storage policies. For full control, you can self-host the server on Fly.io using the provided deployment guide.

How many elements can I evaluate in one request?

The evaluate_typography tool accepts 1–50 elements per call. Each element includes its type, font properties, colors, and optional context.
