## Why The MCP connection manager module had grown to mix orchestration, RMCP client startup, elicitation handling, Codex Apps cache and naming behavior, tool qualification and filtering, and runtime data. The previous stacked PRs split these responsibilities incrementally; this PR collapses that work into one self-contained refactor on latest main. ## What changed - Move McpConnectionManager into connection_manager.rs. - Move RMCP client lifecycle, startup, and uncached tool listing into rmcp_client.rs. - Move elicitation request tracking and policy handling into elicitation.rs. - Move Codex Apps cache, key, filtering, and naming helpers into codex_apps.rs. - Rename the tool-name helper module to tools.rs and move ToolInfo, tool filtering, schema masking, and qualification there. - Move runtime and sandbox shared types into runtime.rs. - Preserve latest main PermissionProfile-based MCP elicitation auto-approval behavior. ## Verification - just fmt - cargo check -p codex-mcp - cargo check -p codex-mcp --tests - cargo check -p codex-core --------- Co-authored-by: Codex <noreply@openai.com>

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.
