A Model Context Protocol (MCP) server and CLI that provides tools for agent use when working on iOS and macOS projects.

CI npm version License: MIT Node.js Xcode 16 macOS MCP Ask DeepWiki AgentAudit Security pkg.pr.new

Installation

XcodeBuildMCP 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 xcodebuildmcp

Option B — npm (Node.js 18+)

npm install -g xcodebuildmcp@latest

Verify either install:

xcodebuildmcp --help

Connect your MCP client

Drop-in config snippets for Cursor, Claude Code, Codex, can be found in the official docs page MCP Clients. Most clients can also run the MCP server on demand via npx -y xcodebuildmcp@latest mcp without a global install.

Requirements

  • macOS 14.5 or later

  • Xcode 16.x or later

  • Node.js 18.x or later (not required for Homebrew installation)

Skills

XcodeBuildMCP now includes two optional agent skills:

  • MCP Skill: Primes the agent with instructions on how to use the MCP server's tools (optional when using the MCP server).

  • CLI Skill: Primes the agent with instructions on how to navigate the CLI (recommended when using the CLI).

To install with a global binary:

xcodebuildmcp init

Or install directly via npx without a global install:

npx -y xcodebuildmcp@latest init

For further information on installing skills, see Agent Skills.

Notes

  • XcodeBuildMCP requests xcodebuild to skip macro validation to avoid errors when building projects that use Swift Macros.

  • Device tools require code signing to be configured in Xcode. See Device Code Signing.

Privacy

XcodeBuildMCP uses Sentry for internal runtime error telemetry only. For details and opt-out instructions, see Privacy & Telemetry.

CLI

XcodeBuildMCP provides a unified command-line interface. The mcp subcommand starts the MCP server, while all other commands provide direct terminal access to tools:

# Install globally
npm install -g xcodebuildmcp@latest

# Start the MCP server (for MCP clients)
xcodebuildmcp mcp

# List available tools
xcodebuildmcp tools

# Build for simulator
xcodebuildmcp simulator build --scheme MyApp --project-path ./MyApp.xcodeproj

# Prepare portable test products without running tests
xcodebuildmcp simulator build --scheme MyApp --project-path ./MyApp.xcodeproj --simulator-name "iPhone 17" --build-for-testing --test-products-path ./MyApp.xctestproducts

# Run previously prepared test products
xcodebuildmcp simulator test --test-products-path ./MyApp.xctestproducts --simulator-name "iPhone 17"

Check for updates and upgrade in place:

xcodebuildmcp upgrade --check
xcodebuildmcp upgrade --yes

The CLI uses a per-workspace daemon for stateful operations (log capture, debugging, etc.) that auto-starts when needed. See the CLI guide for full documentation.
