A3.8/5.0

Scored across 2 tools

Disambiguation4/5

The two tools have clearly distinct purposes: a11y_scanInteractiveByText focuses on testing components via visible text/labels for natural language scenarios, while a11y_scanUrl handles URL-based or element-specific scanning. There is minor potential for confusion since both perform accessibility scans, but their different input methods (text vs. URL/element) and use cases (interactive components vs. general pages) make them mostly distinguishable.

Naming Consistency5/5

Both tools follow a consistent naming pattern with the prefix 'a11y_scan' followed by descriptive suffixes (InteractiveByText and Url). They use snake_case uniformly, and the names clearly indicate their distinct functionalities, making them predictable and easy to understand.

Tool Count3/5

With only two tools, the server feels thin for an accessibility testing domain, which might involve more operations like generating reports, filtering results, or testing specific WCAG criteria. However, the tools cover core scanning functionalities, so it's borderline but not severely lacking.

Completeness3/5

The server provides basic scanning capabilities for URLs and interactive components, but there are notable gaps. Missing operations include result analysis tools (e.g., summarize findings, export reports), configuration options (e.g., custom rule sets), and follow-up actions (e.g., retest after fixes). This limits agents to scanning without deeper workflow support.
