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.

Config for your environment

Replace {MCP_ENDPOINT_URL} with this MCP’s endpoint URL (from its repo or docs above). No API key — you connect directly.

Tool

OS

Config file: ~/.cursor/mcp.json

{
  "mcpServers": {
    "mcp-server": {
      "url": "{MCP_ENDPOINT_URL}"
    }
  }
}

Paste into mcpServers in the config file. Restart Cursor after saving.

If this MCP is also published on mcpchannel.ai, you can subscribe from Browse and use the gateway config there instead.
