A paid MCP server that evaluates typography for accessibility issues beyond what automated scanners catch.

Automated tools (axe, Lighthouse, WAVE) catch roughly 30% of WCAG failures and almost none of the design-judgment failures. Axcess evaluates:

• Contrast ratio with font-weight context — thin fonts require higher ratios than bold fonts at the same size
• Minimum font size for body text, captions, and labels
• Line height adequacy (including for dyslexic users)
• Line length (measure) comfort — too wide or too narrow
• Extended all-caps and italic use
• Letter spacing extremes
• Text on gradient, image, or pattern backgrounds
• Heading hierarchy and visual distinction between levels
• Display type scaling and tracking
• Bringhurst and Lupton design-craft rules beyond WCAG

Add to claude_desktop_config.json (or Cursor MCP settings):

{
  "mcpServers": {
    "axcess": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://axcess-mcp-server.fly.dev/mcp"
      ]
    }
  }
}

Use @x402/fetch to handle payment automatically:

import { wrapFetchWithPaymentFromConfig } from '@x402/fetch';
import { ExactEvmScheme } from '@x402/evm/exact/client';
import { privateKeyToAccount } from 'viem/accounts';

const account = privateKeyToAccount(process.env.EVM_PRIVATE_KEY as `0x${string}`);
const fetchWithPayment = wrapFetchWithPaymentFromConfig(fetch, {
  schemes: [{ network: 'eip155:*', client: new ExactEvmScheme(account) }],
});

const response = await fetchWithPayment(
  'https://axcess-mcp-server.fly.dev/mcp',
  {
