by everettjfMCPXcode provides seamless integration between Xcode and AI assistants using the Model Context Protocol for enhanced developer workflows.
Xcode AI Integration with MCP
Overview
MCPXcode is an open-source implementation of the Model Context Protocol (MCP) for Xcode. It enables seamless integration between Xcode and AI assistants by providing a structured protocol for context exchange and tool execution within the Xcode environment.
