Direct user-configured and plugin MCP servers sit outside the managed connector trust boundary, but Codex currently attaches its raw turn, thread, workspace, plugin, and trace metadata to their tool calls. That leaks host implementation context to arbitrary servers and makes direct egress broader than its intended MCP contract. Introduce a source-derived direct_mcp_v1 profile and enforce it again at the final connection-manager boundary. Direct calls now omit host-generated context and strip reserved OpenAI/Codex metadata supplied through app-server calls while retaining ordinary MCP metadata and sandbox state only when the server negotiated that capability. Compatibility and extension registrations retain host-owned behavior. Hoopa still depends on threadId for its legacy per-thread routing and is registered as an ordinary config server, so temporarily reserve the exact logical name hoopa as host-owned. This is intentional migration debt rather than a trust signal; it can be removed once Hoopa moves to a trusted registration or no longer routes through request metadata. Move authoritative hosted thread metadata behind the profile boundary and remove tests and fixtures that asserted direct servers receive the now-private context.
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.
