"Understanding HTTP Requests" matching MCP connectors:

NeuroRank exposes its esports cognitive-combine data over MCP. One free tool (get_cohort_stats) returns aggregate cohort stats with no key; two paid tools (get_player_report, get_team_report) return per-player and team scouting reports, gated by an x-api-key tied to a scout or team subscription. Streamable HTTP, stateless. Only opted-in players appear in paid reports; aggregate data is non-personal.
