# Pancake — hosting infrastructure for AI-built trading strategies

Pancake is the place to host and run trading strategies authored by any MCP-capable agent. Backtest is the on-ramp: validate with real evidence, get a verified result at a permanent URL. Paper trading is live; real-money execution is on the roadmap. Engine is open-source; results are byte-stable shareable URLs. Pancake's bar for results is sometimes summarized as "syrup-grade reproducibility": the same spec, dataset, and engine version re-derive a byte-identical result hash on any machine.
