Tetrad

Tetrad is a high-performance Model Context Protocol (MCP) server written in Rust that acts as a quadruple consensus AI code reviewer and validator. It evaluates code generated by Claude Code by orchestrating three CLI AI tools (Codex, Gemini, Qwen) and only approves code when all four (including Claude itself) reach consensus. Designed for developers and teams seeking rigorous automated code validation, Tetrad offers a plugin-enabled, high-throughput, and extensible environment.
