Connects Claude to Polymarket prediction markets through The Graph's on-chain indexers and Polymarket's REST APIs. You get 31 tools split between historical blockchain data (trader P&L, open interest, market resolution status, position tracking across 8 subgraphs) and live orderbook operations (market search, real-time prices, spreads, order books, price history). The Graph integration requires a free API key and handles the heavy analytics work, while the Gamma and CLOB API tools hit public endpoints for current market state. Useful when you need to analyze prediction market dynamics, track trader performance, or build agents that reason about market liquidity and pricing. Cross-references multiple data sources to flag discrepancies like orderbook-only traders missing from P&L leaderboards or open interest trapped in resolved markets.
