## Why `codex-mcp` currently exposes more API than the rest of the workspace uses. Some of that surface is simply visibility that can be tightened, and some of it is public helper code that remains compiler-valid because it is exported even though no workspace caller uses it. That distinction matters: Rust does not warn on exported API just because the current workspace does not call it. This PR intentionally treats those exported-but-workspace-unreferenced paths as stale `codex-mcp` surface. The main example is MCP skill dependency collection, where the active implementation now lives in `codex-rs/core/src/mcp_skill_dependencies.rs`; keeping the older `codex-mcp` copy makes it unclear which implementation owns skill MCP installation. ## What Changed - Pruned unused `codex-mcp` re-exports from `codex-mcp/src/lib.rs`. - Removed non-runtime helper methods from `McpConnectionManager` so it stays focused on live MCP clients. - Made `ToolPluginProvenance` lookup methods crate-private. - Removed workspace-unreferenced snapshot wrapper APIs and qualified-tool grouping helpers. - Deleted the duplicate `codex-mcp` skill dependency module and tests now that skill MCP dependency handling is owned by `core`. ## Verification - `cargo check -p codex-mcp`
npm i -g @openai/codex
or brew install --cask codex
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
Install globally with your preferred package manager:
# 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.
