Subagent MCP

An independent MCP server that allows Codex to orchestrate external coding-agent harnesses. It normalizes the lifecycle of external agents (delegate, observe, steer, close) while keeping Codex as the main decision-maker. It supports adapters for Claude Code, DeepSeek, and Grok, ensuring fail-closed safety with no-overage protection and explicit capability gaps.
