**3 tools: 2 change things and 1 only read.**

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `evaluate_typography` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "evaluate_typography" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "evaluate_typography" says "evaluate": a word for a change.
```

- **warn** Annotations that disagree with the tool in `evaluate_accessibility` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "evaluate_accessibility" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "evaluate_accessibility" says "evaluate": a word for a change.
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `evaluate_accessibility`

- The name "evaluate_accessibility" says "evaluate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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
```

### `evaluate_typography`

- The name "evaluate_typography" says "evaluate": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `list_capabilities`

- The name "list_capabilities" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `axcess`:

```json
{
  "permissions": {
    "allow": [
      "mcp__axcess__list_capabilities"
    ],
    "ask": [
      "mcp__axcess__evaluate_typography",
      "mcp__axcess__evaluate_accessibility"
    ],
    "deny": []
  }
}
```

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://axcess-mcp-server.fly.dev/mcp: tools/list returned 3 tools to an anonymous client, including evaluate_typography (write), evaluate_accessibility (write)
