JWT header shape, payload discarded
Scored across 31 tools
Several tools have nearly identical or overlapping purposes, most notably browser-url-ok and playwright-url-ok, whose descriptions are exactly the same. fetch-status, web-fetch, citation, and lib-docs-hint also blur together as HTTP-status checkers, making reliable tool selection difficult.
Names are consistently lowercase and hyphenated, and suffixes like -ok, -shape, and -hint give some signal. However, the set mixes verb-first names such as normalize-url and validate-json with noun-first names such as domain-shape and status-catalog, plus abstract nouns like citation and compatibility, so no single predictable convention is followed.
At 31 tools, the surface is well beyond the 25-tool threshold for a heavy set, and many are trivial one-off utilities such as utc-time, calc-eval, search-query-len, and think-steps. The server would be more coherent with roughly half the tools consolidated into broader validators.
The apparent domain is privacy-preserving URL/input shape checking plus agent index discovery, but the index tools tell agents to follow start_here.hop first while no hop-following tool exists in the set. There are also notable gaps such as no generic hop/redirect handler and no validators for common shapes like email/IP/UUID, which leaves workflows with dead ends.
