Xcode

Using with Apple's Official Xcode MCP: Apple now provides an official Xcode MCP server. XcodeMCP can run alongside it in sidekick mode (--sidekick-only), providing complementary tools like project management and XCResult analysis. In a future version, XcodeMCP will transition to sidekick-only mode by default. See configuration below.

XcodeMCP

Model Context Protocol (MCP) server that controls Xcode directly through JavaScript for Automation (JXA). Available as both an MCP server and a standalone CLI.

What it does

• Controls Xcode directly through JavaScript for Automation (not xcodebuild CLI)
• Opens projects, builds, runs, tests, and debugs from within Xcode
• Parses build logs with precise error locations using XCLogParser
• Provides comprehensive environment validation and health checks
• Supports graceful degradation when optional dependencies are missing
• NEW: Includes a full-featured CLI with 100% MCP server feature parity

Requirements

• macOS with Xcode installed
• Node.js 18+
• XCLogParser (recommended): brew install xclogparser

Usage

XcodeMCP can be used in two ways:

1. MCP Server: Integrate with Claude Desktop, VS Code, or other MCP clients
2. CLI Tool: Run commands directly from the terminal with xcodecontrol

Quick Install

XCLogParser is recommended but optional:

brew install xclogparser

Install from npm

Run directly with npx:

npx -y xcodemcp@latest

Or install globally:

npm install -g xcodemcp

MCP Configuration

Add to your MCP configuration:

{
  "mcpServers": {
    "xcodemcp": {
      "command": "npx",
      "args": ["-y", "xcodemcp@latest"],
      "env": {
      }
    }
  }
}

Claude Code CLI Setup

To add XcodeMCP to Claude Code using the command line:

claude mcp add-json XcodeMCP '{
  "command": "npx",
  "args": ["-y", "xcodemcp@latest"],
  "env": {
  }
}'

Without the clean build folder tool

To add XcodeMCP to Claude Code using the command line:

claude mcp add-json XcodeMCP '{
  "command": "npx",
  "args": ["-y", "xcodemcp@latest", "--no-clean"],
  "env": {
  }
}'

Using Preferred Values for Single Project Workflows

For projects where you're working with a single xcodeproj and scheme, you can configure preferred values to make tool parameters optional:

claude mcp add-json XcodeMCP '{
  "command": "npx",
  "args": ["-y", "xcodemcp@latest"],
  "env": {
    "XCODE_MCP_PREFERRED_SCHEME": "MyApp",
    "XCODE_MCP_PREFERRED_XCODEPROJ": "MyApp.xcodeproj"
  }
}'

With preferred values configured:

• Tool parameters become optional instead of required
• Tool descriptions show default values (e.g., "defaults to MyApp.xcodeproj")
• You can still override defaults by providing explicit parameters
• Reduces repetition when working with a single project

Troubleshooting

If /mcp in Claude Code indicates the MCP failed, try running it from the project folder manually to see what the output is: npx -y xcodemcp@latest

Sidekick Mode

When using XcodeMCP alongside Apple's official Xcode MCP server, enable sidekick mode to only include complementary tools:

• Project management: Open/close projects, manage schemes, workspace info
• XCResult analysis: Browse test results, extract screenshots, inspect UI hierarchies

This excludes build/run/test/debug tools that Apple's MCP handles natively.

Claude Code CLI Setup (Both Servers)

First, enable Xcode Tools in Xcode > Settings > Intelligence > Model Context Protocol.

Then add both Apple's Xcode MCP and XcodeMCP in sidekick mode:

# Add Apple's official Xcode MCP
claude mcp add --transport stdio xcode -- xcrun mcpbridge

# Add XcodeMCP in sidekick mode (project management + XCResult analysis)
claude mcp add-json xcodemcp '{"command": "npx", "args": ["-y", "xcodemcp@latest", "--sidekick-only"]}'

JSON Configuration (Both Servers)

{
  "mcpServers": {
    "xcode": {
      "command": "xcrun",
      "args": ["mcpbridge"]
    },
    "xcodemcp": {
      "command": "npx",
      "args": ["-y", "xcodemcp@latest", "--sidekick-only"]
    }
  }
}

Future direction: In a future version, XcodeMCP will transition to sidekick-only mode by default, focusing exclusively on tools that complement Apple's official Xcode MCP rather than duplicating functionality.

Development Setup

For local development:

git clone https://github.com/lapfelix/XcodeMCP.git
cd XcodeMCP
npm install

# Run in development mode (TypeScript)
npm run dev:ts

# Or build and run compiled version
npm run build
npm start

CLI Usage

XcodeMCP includes a powerful CLI that provides 100% feature parity with the MCP server, allowing you to run any tool as a one-shot command:

Installation

Install globally to use the CLI:

npm install -g xcodemcp

Basic Usage

# Show help and available tools
xcodecontrol --help

# Run a tool with flags  
xcodecontrol build --xcodeproj /path/to/Project.xcodeproj --scheme MyScheme

# Get help for a specific tool
xcodecontrol build --help

# Use JSON input instead of flags
xcodecontrol build --json-input '{"xcodeproj": "/path/to/Project.xcodeproj", "scheme": "MyScheme"}'

# Output results in JSON format
xcodecontrol --json health-check

Path Resolution

The CLI supports both absolute and relative paths for convenience:

# Absolute paths (traditional)
xcodecontrol build --xcodeproj /Users/dev/MyApp/MyApp.xcodeproj --scheme MyApp

# Relative paths (NEW in v2.0.0)
xcodecontrol build --xcodeproj MyApp.xcodeproj --scheme MyApp
xcodecontrol build --xcodeproj ../OtherProject/OtherProject.xcodeproj --scheme OtherApp

# Works with file paths too
xcodecontrol open-file --filePath src/ViewController.swift --lineNumber 42

Relative paths are resolved from your current working directory, making the CLI much more convenient to use when working within project directories.

Verbosity Control

Control logging output with verbosity flags:

# Verbose mode (shows INFO and DEBUG logs)
xcodecontrol -v build --xcodeproj /path/to/Project.xcodeproj --scheme MyScheme

# Quiet mode (only errors)
xcodecontrol -q test --xcodeproj /path/to/Project.xcodeproj

# Default mode (warnings and errors only)
xcodecontrol run --xcodeproj /path/to/Project.xcodeproj --scheme MyScheme

Quick Examples

# Check system health
xcodecontrol health-check

# Build a project
xcodecontrol build --xcodeproj /Users/dev/MyApp/MyApp.xcodeproj --scheme MyApp

# Run the app
xcodecontrol run --xcodeproj /Users/dev/MyApp/MyApp.xcodeproj --scheme MyApp

# Run tests
xcodecontrol test --xcodeproj /Users/dev/MyApp/MyApp.xcodeproj

# Clean build directory
xcodecontrol clean --xcodeproj /Users/dev/MyApp/MyApp.xcodeproj

# Browse XCResult files
xcodecontrol xcresult-browse --xcresult-path /path/to/result.xcresult

# Get UI hierarchy from test failure
xcodecontrol xcresult-get-ui-hierarchy --xcresult-path /path/to/result.xcresult --test-id "MyTest/testMethod()" --timestamp 30.5
