About XcodeBuildMCP

XcodeBuildMCP is an MCP server and CLI for iOS and macOS projects, providing tools for Xcode projects, simulators and app utilities. It can be installed through Homebrew or npm and used either as an MCP server or directly from the terminal.

Key features

  1. 01Xcode project management tools
  2. 02Simulator management tools
  3. 03App utility tools
  4. 04Both MCP server and command-line modes
  5. 05Optional bundled agent skills

Use cases

  1. 01Letting a coding agent build and manage iOS or macOS projects
  2. 02Listing and running Xcode-related tools from the terminal
  3. 03Supporting app debugging in simulators

MCP support

The project runs as an MCP server started with the mobilebuildmcp mcp command, exposing Xcode build and simulator tools to MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

  "mcpServers": {
    "com-xcodebuildmcp-xcodebuildmcp": {

Environment variables to set
INCREMENTAL_BUILDS_ENABLEDEnable experimental xcodemake incremental builds (true/false or 1/0).
XCODEBUILDMCP_ENABLED_WORKFLOWSComma-separated list of workflows to load at startup (e.g., 'simulator,device,project-discovery').
XCODEBUILDMCP_SENTRY_DISABLEDDisable Sentry error reporting (preferred flag).
XCODEBUILDMCP_DEBUGEnable verbose debug logging from the server.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details

From the project README

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

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
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 mobilebuildmcp@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

MobileBuildMCP 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:

mobilebuildmcp init

Or install directly via npx without a global install:

npx -y mobilebuildmcp@latest init

For further information on installing skills, see Agent Skills.

Notes

  • MobileBuildMCP 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

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

CLI

MobileBuildMCP 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 mobilebuildmcp@latest

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

# List available tools
mobilebuildmcp tools

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

# Prepare portable test products without running tests
mobilebuildmcp 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
mobilebuildmcp simulator test --test-products-path ./MyApp.xctestproducts --simulator-name "iPhone 17"

Check for updates and upgrade in place:

mobilebuildmcp upgrade --check
mobilebuildmcp 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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
