# 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 verifiable receipt. Paper trading is live; real-money execution is on the roadmap. Engine is open-source; receipts are byte-stable shareable URLs.
