Xcode MCP Server is an MCP (Model Context Protocol) server that enables AI assistants such as Claude or Cursor to interact with Xcode and Apple platform development directly. It supports discovering and navigating Xcode projects and source files, building and running apps across iOS, macOS, tvOS, and watchOS, and executing tests with detailed results. It can retrieve and present build errors and warnings, capture console output from running applications, and take screenshots of Xcode windows and iOS simulators. It also provides management of simulators and visibility into their status. The server emphasizes security by implementing path-based access control, allowing you to restrict accessible folders with XCODEMCP_ALLOWED_FOLDERS and requiring absolute, existing directory paths. The project notes that it is built with FastMCP and uses AppleScript to communicate with Xcode. Setup requires macOS, Xcode, and Python 3.8+, and can be wired up via Claude Code, Claude Desktop, or Cursor AI clients. It supports CLI options and per-client env settings for access control.
