## Why The current escalate path in `codex-rs/exec-server` still had policy creation coupled to MCP details, which makes it hard to reuse the shell execution flow outside the MCP server. This change is part of a broader goal to split MCP-specific behavior from shared escalation execution so other handlers (for example a future `ShellCommandHandler`) can reuse it without depending on MCP request context types. ## What changed - Added a new `EscalationPolicyFactory` abstraction in `mcp.rs`: - `crate`-relative path: `codex-rs/exec-server/src/posix/mcp.rs` - https://github.com/openai/codex/blob/main/codex-rs/exec-server/src/posix/mcp.rs#L87-L107 - Made `run_escalate_server` in `mcp.rs` accept a policy factory instead of constructing `McpEscalationPolicy` directly. - https://github.com/openai/codex/blob/main/codex-rs/exec-server/src/posix/mcp.rs#L178-L201 - Introduced `McpEscalationPolicyFactory` that stores MCP-only state (`RequestContext`, `preserve_program_paths`) and implements the new trait. - https://github.com/openai/codex/blob/main/codex-rs/exec-server/src/posix/mcp.rs#L100-L117 - Updated `shell()` to pass a `McpEscalationPolicyFactory` instance into `run_escalate_server`, so the server remains the MCP-specific wiring layer. - https://github.com/openai/codex/blob/main/codex-rs/exec-server/src/posix/mcp.rs#L163-L170 ## Verification - Build and test execution was not re-run in this pass; changes are limited to `mcp.rs` and preserve the existing escalation flow semantics by only extracting policy construction behind a factory. --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

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.
