tom_doerr · x · 2026-08-10

MCO is a lightweight, CLI-first orchestration layer designed for AI coding agents. Its core functionality allows users to assign a single task to multiple chosen agents and models simultaneously, running them in parallel to compare their raw answers before taking action.

The tool is built for workflows like code review, implementation, architecture analysis, and CI checks, aiming to mitigate blind spots of individual models. It operates directly from the terminal and integrates with existing coding agents like Claude Code, Codex, and Cursor.
