## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-24.

- **Supply Chain Security**: 81/100
  - No malware found by supply-chain analysis.
  - CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available.
  - No install/post-install scripts declared.
  - 31 of 97 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 6/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - Licence could not be checked: the licence is shipped as a file inside the package, not declared as a standard (SPDX) licence identifier, so we cannot tell whether it is OSI-approved.
  - Actively maintained (last published 1 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 78/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 581 tokens (~290/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `check_accessibility` (~271 tokens)

Check accessibility

Runs the AccessLumens accessibility scanner (axe-core plus AccessLumens keyboard, focus and reflow checks) in a local headless browser and returns a 0-100 score and every issue: severity, WCAG success criteria, how to fix it, and each failing element's CSS selector, markup and the reason it failed. Works on localhost and other local addresses, public URLs, and local .html files or folders. Takes about 10-60 seconds per page. Re-run after fixing to verify. A clean result covers only what automation can detect: before reporting the work as done, also review the source for repeated buttons or links with the same name and alt text that repeats nearby text.

Input parameters:

- `crawl` (boolean): Follow same-site links and test up to 10 pages instead of only this one.
- `keyboard` (boolean): Also test keyboard access: unreachable controls, keyboard traps, invisible focus, skip links, and reflow at 320px. Slower; turn off for a quick check.
- `max_issues` (integer): Most issue types to return, most severe first.
- `url` (string, required): Page to scan: a URL (http://localhost:3000/checkout, https://example.com), or a path to a local .html file or folder.

### `explain_issue` (~88 tokens)

Explain an accessibility rule

Explains one accessibility rule from a check_accessibility result: what it means, who it affects, how to fix it, the WCAG success criteria it maps to (with W3C links), and a reference page.

Input parameters:

- `rule_id` (string, required): The rule id shown in a check_accessibility result, e.g. "color-contrast", "button-name", "keyboard-trap".
