XcodeMCP

MCP server for Xcode build automation and log parsing.

What it does

• Opens Xcode projects and triggers builds in Xcode, not using xcodebuild. [^1]
• Parses build logs to extract errors and warnings using XCLogParser
• Provides MCP tools for AI assistants to interact with Xcode

[^1]: For an alternative that uses xcodebuild, see XcodeBuildMCP

Requirements

• macOS with Xcode installed
• Node.js 18+
• XCLogParser: brew install xclogparser
