Reins MCP
Reins is an open-source MCP server that provides risk limits and an audit log for AI agents trading on Hyperliquid. It enforces constraints such as position size, leverage, and daily loss outside the model, ensuring agents cannot bypass safety rules. It supports paper trading on live prices and logs every decision with the agent's reasoning for transparency and post-trade analysis.
