graph-polymarket-mcp
MCP server for querying Polymarket prediction market data via The Graph subgraphs and Polymarket REST APIs.
Exposes 31 tools that AI agents (Claude, Cursor, etc.) can use to search markets, get real-time CLOB prices and order books, query on-chain data, trader P&L, positions, activity, open interest, market resolution status, and trader profiles.
v2.0.0 — adds 10 new tools powered by Polymarket's Gamma and CLOB APIs (inspired by polymarket-cli): market search, event browsing, live prices, spreads, order books, price history, and more. No API key needed for these tools — they hit Polymarket's public REST endpoints directly.
