Nexus

Acerca de

Nexus is an MCP server designed to empower AI models by allowing them to seamlessly invoke other AI CLI agents, such as Gemini CLI, Codex, and Claude Code, as robust tools. It significantly enhances AI workflows by providing capabilities like parallel execution for simultaneous task processing, automatic retries with exponential backoff for increased reliability, and sophisticated JSON-first response parsing. This enables advanced use cases such as multi-agent research and summarization, comprehensive code reviews across different agents, comparative analysis of model outputs, and efficient bulk content generation, all while reducing single-model bias and improving overall productivity.

Características Principales

• Parallel execution of prompts across multiple agents with configurable concurrency.
• Multiple execution modes: 'default' (safe), 'sandbox' (restricted), and 'yolo' (full auto-approve).
• Automatic retries with exponential backoff for handling transient errors.
• 1 GitHub stars
• JSON-first output parsing, with fallback mechanisms for noisy stdout and temp-file spillover for large outputs.
• Automatic detection of CLI agent binary paths, versions, and JSON output capabilities at startup.

Casos de Uso

• Multi-model comparison to prompt the same question to different models and compare outputs for quality or consistency.
• Research & summarization by fanning out topics to multiple agents and synthesizing diverse perspectives.
• Code review by sending different files or review angles to separate agents simultaneously.
