XcodeBuildMCP is a tool that connects AI coding assistants, such as Claude Code or Cursor, to Xcode, Apple's development environment for building iOS and macOS apps. It does this through a standard called the Model Context Protocol, which lets AI agents call tools and receive structured results rather than just reading or writing text. The practical effect is that an AI assistant can trigger builds, run tests, launch apps in a simulator, and inspect build logs without you having to copy-paste terminal output back and forth. The package ships as both a command-line tool and an MCP server. You can use the command line directly from a terminal to build for a simulator, list available tools, or check for updates. You point the CLI at your Xcode project file and specify a build scheme, and it calls Xcode's underlying build system on your behalf. The MCP server mode is what AI coding agents connect to when you configure them to use it, which turns those same capabilities into callable functions the agent can invoke during a conversation. Installation requires macOS 14.5 or later and Xcode 16 or later. You can install the package globally through Homebrew or npm. Clients that support MCP, including Cursor, Codex, and Claude Code, can also run it on demand without a global install using a single npx command. Configuration snippets for each supported AI client are linked from the documentation site. The project is maintained by Sentry, the error-monitoring company. It uses Sentry's own telemetry to collect internal runtime errors, with opt-out instructions in the privacy documentation. An optional "skills" feature lets you load instructions into an AI agent that explain how to use the CLI or the MCP server effectively. The project is released under the MIT license.
