Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package xcodebuildmcp
Claude Code 
claude mcp add xcodebuildmcp -e 'INCREMENTAL_BUILDS_ENABLED=false' -e 'XCODEBUILDMCP_ENABLED_WORKFLOWS=<XCODEBUILDMCP_ENABLED_WORKFLOWS>' -e 'XCODEBUILDMCP_SENTRY_DISABLED=false' -e 'XCODEBUILDMCP_DEBUG=false' -- npx -y xcodebuildmcp@2.7.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "xcodebuildmcp": {
            "command": "npx",
            "args": [
                "-y",
                "xcodebuildmcp@2.7.0"
            ],
            "env": {
                "INCREMENTAL_BUILDS_ENABLED": "false",
                "XCODEBUILDMCP_ENABLED_WORKFLOWS": "<XCODEBUILDMCP_ENABLED_WORKFLOWS>",
                "XCODEBUILDMCP_SENTRY_DISABLED": "false",
                "XCODEBUILDMCP_DEBUG": "false"
            }
        }
    }
}

Environment variables

  • INCREMENTAL_BUILDS_ENABLED Enable experimental xcodemake incremental builds (true/false or 1/0).
  • XCODEBUILDMCP_ENABLED_WORKFLOWS Comma-separated list of workflows to load at startup (e.g., 'simulator,device,project-discovery').
  • XCODEBUILDMCP_SENTRY_DISABLED Disable Sentry error reporting (preferred flag).
  • XCODEBUILDMCP_DEBUG Enable verbose debug logging from the server.

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

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.
