## Summary - attach the authoritative Codex thread id to MCP tool request `_meta.threadId` for model-initiated tool calls - attach the same thread id for manual `mcpServer/tool/call` requests before invoking the MCP server - cover both metadata helper behavior and the manual app-server MCP path in tests needed because the Rust app-server is the last place that still has authoritative knowledge of “this model-generated MCP tool call belongs to conversation/thread X” before the request leaves Codex and reaches Hoopa. It adds threadId to MCP request metadata in the model-generated tool-call path, using sess.conversation_id, and also does the same for the manual mcpServer/tool/call path. ## Test plan - `cargo test -p codex-core mcp_tool_call_thread_id_meta_is_added_to_request_meta --lib` - `cargo test -p codex-app-server mcp_server_tool_call_returns_tool_result` Paired Hoopa consumer PR: https://github.com/openai/openai/pull/833263

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.
