Nexus

Enables AI models to invoke AI CLI agents (Gemini CLI, Codex, Claude Code, OpenCode) as tools with parallel execution and automatic retries.

Provides a bridge for AI models to orchestrate multiple AI CLI agents as MCP tools. Supports parallel execution via asyncio with configurable concurrency, automatic retries with exponential backoff, JSON-first response parsing, and structured output. Includes session preferences, tool timeouts, client-visible logging, and MCP elicitation for interactive parameter resolution. Compatible with Gemini CLI, Codex, Claude Code, and OpenCode runners.
