Backtest Auditor MCP

A local MCP server that performs red-team checks on trading backtests to detect lookahead bias, survivorship bias, ticker reuse, unrealistic costs, overfitting, sub-period instability, and concentration. It provides tools to audit code, returns, and trade logs, generating reports on errors that make backtests look better than they are.
