Contrast ratio for two hex colors
Scored across 31 tools
Many tools overlap heavily: browser-url-ok and playwright-url-ok have identical descriptions, while fetch-status, web-fetch, citation, normalize-url, and inspect-robots all inspect URLs in similar ways. The tool named contrast-ok is the only one related to the server's stated purpose, making the rest of the set extremely unclear.
There is a loose suffix pattern (-ok, -shape, -hint, -index), but verbs and styles are mixed: some are noun-based (timezone), some are verb-object (normalize-url, validate-json), and some use vague names like web-fetch or citation. The inconsistency makes the set feel uncoordinated.
31 tools is far too many for a server whose stated purpose is computing a contrast ratio between two hex colors. While the count is not extreme enough for a 1, the vast majority of tools are unrelated to the server name, making the scope appear bloated and unfocused.
For the named purpose (contrast ratio), the surface is barely complete—only contrast-ok exists with no additional color or accessibility helpers. For the broader set of URL/time/JSON utilities, there is no coherent domain and obvious gaps (e.g., no actual page content fetching, no DNS, no color conversion), so coverage cannot be meaningfully assessed.
