What it does

gpt2agent exposes **25 MCP tools** that forward requests directly to ChatGPT's backend API. No proxy process. No separate account. No platform API key. Your `codex login`, your token, your quota.

If you already have the [`codex`](https://github.com/openai/codex) CLI logged in, setup is **zero extra steps** — gpt2agent reuses `$CODEX_HOME/auth.json` (or `~/.codex/auth.json` by default) and picks up its background-refreshed token automatically.

Works with Claude Code, Codex CLI, and any client that speaks the MCP protocol over stdio.
