PerpRadar

With only one tool there is no cross-tool ambiguity an agent could stumble into, so selection is trivial. However, the single tool internally bundles many distinct capabilities (positioning read, funding, open interest, history, scan), so the boundaries of what it actually returns are not sharp.

The single name perp_positioning is clear, lowercase snake_case, and domain-appropriate. It is a noun phrase rather than the common verb_noun convention, but with one tool there is no inconsistency to penalize.

The description advertises at least five distinct analytical surfaces (/v1/funding, /v1/lite, /v1/full, /v1/scan, plus the preview positioning read), yet only one tool is exposed. The surface feels under-scoped relative to the described domain.

Key capabilities like funding history, cross-venue scans for extremes/spreads, and open-interest breakdowns are mentioned only as paid HTTP routes, not as callable tools, leaving agents with dead ends. A single opaque tool cannot let an agent compose queries like scanning a universe or pulling 7-day history.
