How is the effective price calculated?

The effective price is the listed platform price adjusted by the platform's fee rate. For example, if a price is 0.50 and the fee is 2%, the effective price is 0.49.

What does `analyze_arbitrage_opportunity` return?

It returns the direction of the trade, the cheapest and most expensive platforms, the net profit percentage, absolute profit, capital lockup days, and the minimum trade size.

How do I account for gas fees?

Include all one-time fixed costs, such as network gas fees, in the `fixedTransactionFees` parameter when calling the analysis tools.

This MCP server provides deterministic analysis for prediction market arbitrage. It calculates effective prices by adjusting listed prices for platform-specific fee structures, identifies directional arbitrage opportunities, and determines the minimum trade size needed to overcome fixed transaction costs. Use analyze_arbitrage_opportunity to find profitable spreads between Polymarket, PredictIt, and Kalshi, or calculate_lockup_and_liquidity to project capital lockup duration and break-even requirements.
