[Codex Thread 019ef1f9-36e2-7e91-9337-504f097b9dc1](https://codex-thread-link.openai.chatgpt-team.site/thread/019ef1f9-36e2-7e91-9337-504f097b9dc1) ## Why Hosted plugin-service Streamable HTTP MCP traffic uses `https://chatgpt.com/backend-api/ps/mcp` and depends on Cloudflare's `__cflb` cookie for load-balancer affinity. The local and exec-server `http/request` path built a fresh reqwest client for each request without installing Codex's existing shared ChatGPT Cloudflare cookie store, so affinity could be lost between calls. This is an affinity-hardening change motivated by an incident investigation. It does not establish the broader connector-cache incident RCA or claim to fix that incident in full. ## What changed - Install the existing process-local, strictly allowlisted ChatGPT Cloudflare cookie store on the reqwest client used by `ReqwestHttpClient`. - Fresh clients now share allowed Cloudflare infrastructure cookies within the process that originates the local or exec-server network request. - Keep the existing HTTPS ChatGPT-host and Cloudflare-cookie-name restrictions. This does not introduce a general cookie jar or send ChatGPT Cloudflare cookies to unrelated hosts. ## Test coverage - `codex-client` unit coverage verifies that the existing strict store accepts and returns `__cflb` for HTTPS ChatGPT URLs. - The exec-server HTTPS integration test sends four independent `http/request` calls through a local TLS-intercepting proxy and verifies that: - `Set-Cookie: __cflb=west` is sent on the next plugin-service request; - a later `Set-Cookie: __cflb=central` replaces the stored value; - non-Cloudflare session cookies are discarded; - no stored ChatGPT Cloudflare cookie is sent to a non-ChatGPT host. - `just test -p codex-client` — 38 passed. - `just test -p codex-exec-server --test chatgpt_cloudflare_affinity` — 1 passed. - `just bazel-lock-check` — passed. ## Non-goals - No persistence of ChatGPT auth, account, session, residency, or arbitrary cookies. - No cookie persistence for third-party MCP servers. - No special composition of caller-provided `Cookie` headers. - No plugin-service, connector-cache, Habitat/habicache, routing, redirect, or API-contract changes. - No broader incident RCA conclusions.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
Using Codex with your ChatGPT plan
Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.
You can also use Codex with an API key, but this requires additional setup.
