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