Set up xcrew for this iOS project — write MobileBuildMCP's config with the right workspace, schemes and simulators, then check the Mac. Use when the person runs /xcrew:setup, when Xcrew says MobileBuildMCP "has no scheme to build this project with yet", or when they ask to change which scheme or simulator Claude builds and tests with.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Set up xcrew in this project In a git worktree whose main checkout is set up, run `xcrew setup --worktree` instead of the steps below: it writes this worktree's config from the main checkout's, with simulators of its own, and prints the calls that give this session's MobileBuildMCP its profiles. Then do steps 4 and 5. 1. Find the choices, without asking for what you can look up: - **Container:** run `xcrew project --setup`. Its JSON names the `container` setup will build. When it has a `containerProblem` instead, explain it to the person in your own words and ask: which of the folders it lists to use, or to generate the workspace first, then run `xcrew project --setup` again. - **Schemes:** MobileBuildMCP's `list_schemes` on that container. Pick the app scheme and, if there is one, the UI-test scheme. Leave the unit-test scheme to `xcrew setup`. - **Bundle ID:** `get_app_bundle_id`, or the app target's `PRODUCT_BUNDLE_IDENTIFIER` from `show_build_settings`. …

How to install
mdr add breferrari/xcrew/setup@sha256:beb64e9151196783The line at the top of this page pins the label git:20261103.786b5e9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
