The three tools target distinct operations (single-service availability, single-service evidence, and service search) and the descriptions explicitly draw boundaries. However, search_available_services claims to return 'scope, evidence, limitations, and availability timestamps,' which overlaps with what the other two tools provide, creating mild ambiguity about when to use each.

All names follow a clear snake_case verb-first pattern (check_, get_, search_). The noun phrasing varies a bit ('availability' vs 'service_evidence' vs 'available_services'), which is a minor deviation but still predictable.

Three tools is at the low end of the appropriate range, and for a deliberately read-only discovery server each tool earns its place. It is slightly thin, with no clearly separate tool for browsing or filtering.

For a reviewed-services registry the read surface covers search, per-service evidence, and per-service availability, with scope/limitations reported. Since the server intentionally stops short of reserving, contacting, or ordering, the missing write operations are by design rather than gaps.
