# Oracle3 **Oracle3 is an open-source trading engine and MCP server for prediction markets.** It maps the logical relations between event contracts, finds prices that break the axioms of probability after each venue's fees, and trades them live on Kalshi, Polymarket and Solana, or on paper, under pre-trade risk limits. > **Trades live on Kalshi, Polymarket and Solana.** `oracle3 live run` executes with the same engine that runs paper trading, behind pre-trade risk limits and a kill switch.
