Tetrad

Tetrad is a high-performance MCP (Model Context Protocol) server designed to act as a consensus and validation layer for AI-generated code. Written in Rust, Tetrad orchestrates three external AI CLI code evaluation tools—Codex, Gemini CLI, and Qwen—to validate and approve all code produced by Claude Code, ensuring high reliability and accuracy through a quadruple consensus protocol. The system is suitable for developers and teams looking to add multiple AI-based guardrails to their code generation workflows, especially when using Claude Code for automated software development tasks.
