# Dispatching GPT via Codex MCP ## Overview You dispatch a task to GPT running as a Codex agent. It has its own sandbox and blank context — it sees nothing of your session, so you construct exactly what it needs. The value is that it is a *different model*: second opinion, adversarial review, or a parallel executor. **Core principle:** One `codex` call = one independent GPT agentic turn. Reuse the `threadId` to continue; review its diffs before trusting them. **Prerequisite — set it up on first use.** This skill needs the tools `mcp__gpt-codex__codex` and `mcp__gpt-codex__codex-reply`. If they're absent, provision them now, then tell the user to restart Claude Code (MCP tools only load at startup): 1. **Codex CLI + auth** — run `codex login status`. If Codex isn't installed or isn't logged in, tell the user to run `npm i -g @openai/codex && codex login` (interactive browser auth — only they can complete it). 2. **Register the server yourself** (user-level): - macOS/Linux: `claude mcp add gpt-codex -s user -- codex mcp-server -c sandbox_mode=workspace-write -c approval_policy=never` - Windows (run from PowerShell, or prefix `MSYS_NO_PATHCONV=1` in Git Bash — else `/c` mangles to `C:/`): `claude mcp add gpt-codex -s user -- cmd /c codex mcp-server -c sandbox_mode=workspace-write -c approval_policy=never` - Equivalent: copy the bundled [references/mcp.json](references/mcp.json) (macOS/Linux) or [references/mcp.windows.json](references/mcp.windows.json) (Windows) in
