Returns available evaluation tools, what they check, and their pricing. Call this first to understand what Axcess can evaluate and how much each evaluation costs. This tool is FREE. All evaluation tools require USDC payment on Base network. Returns: JSON with tool descriptions, pricing, and rubric categories.

Evaluates typography elements against a principled accessibility rubric. COST: $0.05 USDC via x402 on Base-compatible EVM network per call. Goes beyond what axe/Lighthouse/WAVE can check — evaluates design judgment, not just numeric compliance. Catches issues like: - Contrast that passes WCAG 4.5:1 but fails visually due to thin font weight - Body text that meets minimum size requirements but is still too small for comfortable reading - Line heights that technically comply but impede readability for dyslexic users - Extended all-caps or italic text that passes all AA criteria but impairs reading - Text on gradient/image backgrounds where scanner sampling is unreliable - Heading sizes that are technically correct but visually indistinct from body Args: - elements: Array of 1–50 typography element objects with font/color properties - screen_name: Optional label for the evaluation report Each element requires: element_type, font_size, font_weight, line_height, color_hex, background_color_hex. Returns: Structured report with: - Per-element scores (0–100) - Specific issues with severity (critical/major/minor) - WCAG references and what automated tools miss - Concrete fix recommendations - Overall score and verdict (pass/needs_work/fail) - Top issues sorted by severity Example use: Extract text layer properties from Figma using get_design_context, pass the typography properties to this tool for evaluation before shipping.

Evaluates UI elements for accessibility issues that automated scanners miss. COST: $0.01 USDC via x402 on Base-compatible EVM network per call. Checks beyond what axe/Lighthouse/WAVE catch at the design stage: - Touch targets below 24×24px (WCAG 2.5.8 AA hard fail) - Touch targets below 44×44px (WCAG 2.5.5 AAA recommended) - Information conveyed by color alone without a secondary indicator (WCAG 1.4.1) - Missing focus indicators on interactive elements (WCAG 2.4.7) - Focus rings thinner than 2px (WCAG 2.4.11) - Focus ring contrast below 3:1 against adjacent background (WCAG 2.4.11) - Interactive elements below the practical usability height floor Args: - elements: Array of 1–50 UI element objects - screen_name: Optional label for the evaluation report Each element requires: element_type. Provide width_px/height_px for touch target checks. Provide uses_color_only + secondary indicator flags for 1.4.1 checks. Provide is_interactive + focus_visible + focus indicator properties for focus checks. Returns: Structured report with: - Per-element scores (0–100) and specific issues - Severity levels (critical/major/minor) with WCAG references - What automated tools miss and why - Concrete fix recommendations - Overall score and verdict (pass/needs_work/fail) - Top issues sorted by severity

Overview

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.

  • Identifies all-caps, italic, and letter-spacing issues
  • Analyzes text on gradient, image, or pattern backgrounds
  • Reviews heading hierarchy and display type scaling
  • Applies Bringhurst and Lupton design-craft rules

Use cases of Axcess

  • Auditing hero section typography for both WCAG and design-craft compliance

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.
