Kalshi Kernel MCP

An unofficial, safety-focused MCP server for Kalshi event contracts and perpetual markets. It provides a narrow boundary for agents with explicit intent, strict schemas, and strong separation between simulation and real-money execution. Features include paper mode by default, immutable execution mode, fixed-point strings for prices, and generated tool schemas with safety annotations.
