XcodeBuildMCP

A Model Context Protocol (MCP) server that provides Xcode-related tools for integration with AI assistants and other MCP clients.

Overview

This project implements an MCP server that exposes Xcode operations as tools that can be invoked by AI agents via the MCP protocol. It enables programmatic interaction with Xcode projects through a standardised interface, optimised for agent-driven development workflows.

Why?

The XcodeBuild MCP tool exists primarily to streamline and standardise interaction between AI agents and Xcode projects. By providing dedicated tools for common Xcode operations, it removes reliance on manual or potentially incorrect command-line invocations.

This ensures a reliable and efficient development process, allowing agents to seamlessly leverage Xcode's capabilities while reducing the risk of configuration errors.

Critically, this MCP enables AI agents to independently validate code changes by building projects, inspecting errors, and iterating autonomously. In contrast to user-driven tools like Sweetpad, XcodeBuild MCP empowers agents to automate these workflows effectively.

Features

The XcodeBuildMCP server provides the following tool capabilities:

Xcode project management

• Build Operations: Platform-specific build tools for macOS, iOS simulator, and iOS device targets
• Project Information: Tools to list schemes and show build settings for Xcode projects and workspaces
• Clean Operations: Clean build products using xcodebuild's native clean action

Simulator management

• Simulator Control: List, boot, and open iOS simulators
• App Deployment: Install and launch apps on iOS simulators

App utilities

• Bundle ID Extraction: Extract bundle identifiers from iOS and macOS app bundles
• App Launching: Launch built applications on both simulators and macOS

Getting started

Prerequisites

• Node.js (v16 or later)
• npm
• Xcode command-line tools

Installation

1. Clone the repository
2. Install dependencies:

   npm install
   

3. Build the project:

   npm run build
   

4. Optionally start the server:

   node build/index.js
   

[!NOTE] You don't need to run the server manually as MCP clients will do this for you.

Adding to Windsurf/Cursor/Clude Desktop etc.

Create a new custom server configuration and add the following; changing the path to the actual path you cloned the repo to.

{
  "mcpServers": {
    "XcodeBuildMCP": {
      "command": "node",
      "args": [
        "/path_to/XcodeBuildMCP/build/index.js"
      ]
    }
  }
}

Debugging

You can use MCP Inspector via:

npx @modelcontextprotocol/inspector node build/index.js
