## Why The memories MCP `search` tool only accepts a single substring today, which makes it hard for clients to express combined queries or explain why a line matched. This change adds the richer search shape needed for the next client iteration while keeping the legacy single-`query` call working. ## What changed - accept either the legacy `query` field or a new `queries` array, plus `match_mode: any|all` - teach the local memories backend to evaluate multi-query line matches and return `matched_queries` on each hit - update the MCP input/output schema and add coverage for parser behavior, ordering, pagination, case sensitivity, and match modes ## Testing - added unit coverage in `memories/mcp/src/local_tests.rs` and `memories/mcp/src/server.rs`
npm i -g @openai/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.
