Installation

MobileBuildMCP ships as a single package with two modes: a CLI for direct terminal use and an MCP server for AI coding agents. Either install method gives you both.

Option A — Homebrew

brew tap getsentry/xcodebuildmcp
brew install mobilebuildmcp

Option B — npm (Node.js 18+)

npm install -g mobilebuildmcp@latest

Verify either install:

mobilebuildmcp --help

What it tells the agent

The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

# MobileBuildMCP CLI

Use MobileBuildMCP tools via the `mobilebuildmcp` executable instead of raw `xcodebuild`, `xcrun`, or `simctl`.

## Step 1: Ensure the CLI Exists

Check availability:
```bash
mobilebuildmcp --help
```

If missing, install with one of:
```bash
brew tap getsentry/xcodebuildmcp
brew install mobilebuildmcp
```

```bash
npm install -g mobilebuildmcp@latest
```

Re-check after install:
```bash
mobilebuildmcp --help
```

## Step 2: Use Help-First Discovery

Discover workflows and arguments from the CLI itself:
```bash
mobilebuildmcp --help
mobilebuildmcp tools
mobilebuildmcp <workflow> --help
mobilebuildmcp <workflow> <tool> --help
```

Use this discovery path instead of memorizing static tool lists.

## Step 3: Keep Execution Minimal

- Choose the smallest command sequence that satisfies the request.
- Prefer direct workflow commands over manual multi-step chains unless explicitly requested.
- For simulator run intent, prefer the combined `build-and-run` command.
- Do not chain `build` then `build-and-run` unless explicitly requested.

## Capability Overview

`mobilebuildmcp` supports:
- simulator and device build/test/run
- debugging and log capture
- UI automation
- project discovery and scaffolding
- session defaults and workflow configuration

## Exit Criteria

- CLI presence is verified or installation steps are provided.
- Commands are discovered via `--help` / `tools`.
- Session defaults are checked before first build/run/test action.

What can xcodebuildmcp — cameroncooke/xcodebuildmcp access on my machine?

The audit observed that it reaches the network, runs shell commands and reads or writes files. Each of those is consistent with what it says it does. Secrets in the source: none found.

Which assistants does xcodebuildmcp — cameroncooke/xcodebuildmcp work with?

Its documentation mentions claude-code, codex and cursor. That is what the text claims, not a compatibility test we ran.

How current is this page?

The grade is for one exact copy of the source (a8e6e2fdb267), read on 2026-10-20. The repository is watched, and a new audit runs when it changes — this is the first audit.
