What is Xcode MCP Server?
A Model Context Protocol (MCP) server that acts as a bridge between Claude and your local Xcode projects. It enables intelligent code assistance, project management, and automated development tasks while keeping all communication on your machine—your code is never exposed to the internet.
How to use Xcode MCP Server?
Install via NPM (npx -y @modelcontextprotocol/xcode-server), global NPM install, or from source. Set the PROJECTS_BASE_DIR environment variable to your Xcode projects directory, then add the server configuration to your Claude Desktop config file (claude_desktop_config.json). After restarting Claude, you can ask natural language requests like “Create a new SwiftUI view” or “Build the project in Debug configuration.”
