## Summary Codex Apps file parameters are exposed to the model as local paths, uploaded at execution time, and rewritten into provided-file payloads before the MCP tool call. The rewrite currently forwards two internal upload fields, `uri` and `file_size_bytes`, even though they are not part of the documented app file-reference shape. Strict app schemas can reject those extra fields before execution. ## Changes - Stop copying `uri` and `file_size_bytes` into app-facing MCP arguments. - Keep the internal `UploadedOpenAiFile` result unchanged. - Preserve the existing `download_url`, `file_id`, `mime_type`, and `file_name` behavior for scalar and array file inputs. - Verify the MCP invocation and post-tool hook receive exactly the documented four-field payload against an `additionalProperties: false` schema. This intentionally does not add schema inspection or change how `openai/fileParams` names are discovered. ## Validation - `just test -p codex-core mcp_openai_file` (6 passed) - `just test -p codex-core codex_apps_file_params_` (2 passed) - `just fix -p codex-core` - `just fmt` - `git diff --check`
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.
