Zen functions as a Model Context Protocol (MCP) server that empowers CLI-based AI agents, such as Claude Code, Gemini CLI, or Codex CLI, to access and orchestrate a diverse team of AI models. It facilitates true AI collaboration with seamless conversation continuity, enabling complex workflows like multi-model code reviews, automated planning, and pre-commit validation to occur within a single, continuous conversation thread. By allowing models to 'remind' each other of past context and delegating subtasks based on their specific strengths, Zen ensures thorough analysis, extends context windows beyond individual model limits, and keeps the user in full control of their AI development team.
