Xcode 26.3 ships with mcpbridge, exposing 20 IDE tools to AI clients, and this covers the full stack: first-time setup for Claude Code, Cursor, or other MCP clients, the build/test/preview workflow patterns, tool reference with schemas, and troubleshooting when connections fail or permission dialogs confuse you. It's split into three sub-skills (setup, tools, reference) with clear routing so you don't waste time on wrong docs. The anti-rationalization table is honest about when MCP beats raw xcodebuild (IDE state, diagnostics, previews). If you're trying to wire up an AI assistant to Xcode's internals, this is the manual you actually need, not Apple's sparse release notes.
