Polymarket MCP Server

Forty-five tools divide across market discovery, market analysis, order placement, portfolio tracking and real-time monitoring, working against Polymarket's central limit order book with GTC, GTD, FOK and FAK limit orders, market orders, batch submission and bulk cancellation. Authentication is two-layered by protocol design: an L1 wallet private key signs orders under EIP-712 while an L2 API key handles everything else. The section to read before enabling writes is risk configuration, which caps order size, total portfolio exposure and per-market position, refuses execution below a minimum liquidity or above a maximum spread, and asks for explicit confirmation on large orders. The WebSocket layer streams prices, order-book depth and resolution events, reconnecting with exponential backoff after a drop.
