## Why `codex-tools` already owns the shared tool input schema model and parser from the first extraction step, but `core/src/tools/spec.rs` still owned the MCP-specific adapter that normalizes `rmcp::model::Tool` schemas and wraps `structuredContent` into the call result output schema. Keeping that adapter in `codex-core` means the reusable MCP schema path is still split across crates, and the unit tests for that logic stay anchored in `codex-core` even though the runtime orchestration does not need to move yet. This change takes the next small step by moving the reusable MCP schema adapter into `codex-tools` while leaving `ResponsesApiTool` assembly in `codex-core`. ## What changed - added `tools/src/mcp_tool.rs` and sibling `tools/src/mcp_tool_tests.rs` - introduced `ParsedMcpTool`, `parse_mcp_tool()`, and `mcp_call_tool_result_output_schema()` in `codex-tools` - updated `core/src/tools/spec.rs` to consume parsed MCP tool parts from `codex-tools` - removed the now-redundant MCP schema unit tests from `core/src/tools/spec_tests.rs` - expanded `codex-rs/tools/README.md` to describe this second migration step ## Test plan - `cargo test -p codex-tools` - `cargo test -p codex-core --lib tools::spec::`
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.
