Gives Claude direct access to Polymarket's prediction markets through LemonCake's pay-per-call billing layer. You can buy and sell positions in real-money prediction markets using USDC, settled on-chain via ERC-2612 permits. Sign once for 90 days with a daily spending cap, and the agent can autonomously trade on events without holding your funds or prompting for signatures on every call. Built on the same infrastructure as LemonCake's other trading MCPs (xstocks, Alpaca, Dinari). Useful when you want an agent to take positions based on research, news analysis, or portfolio rebalancing logic without manually executing each trade or worrying about runaway spending.
