PolyRank

MCP server that gives AI agents (Claude, etc.) direct access to Polyrank — the skill-analytics layer for Polymarket. It ranks millions of Polymarket wallets by genuine forecasting skill (calibration / Brier, alpha-vs-mid, risk-adjusted return) — not vanity P&L or win rate. Follow the skilled, not the lucky. (Live coverage + the exact skill-metric count: polyrank_get_platform_stats.)

It wraps Polyrank's free public API. Deep / premium data (full Brier decomposition, alpha, smart-money positioning) is billed per-request via x402 (USDC on Base) — see https://polyrank.app/llms.txt.
