MCP server that puts guardrails around delegating work to OpenAI Codex: quota preflight and handoff, git worktree isolation, checkpoints, and read-only cross-review.
An MCP server that puts guardrails around delegating work to OpenAI Codex. Codex already ships its own MCP server (`codex mcp-server`), and it exposes two tools: `codex` and `codex-reply`. If all you want is "run a Codex session from another agent", use that — it is first-party and costs you nothing to maintain.
