**Production-grade MCP server for Xcode workflows — optimized for AI agents with accessibility-first iOS automation**

XC-MCP makes Xcode and iOS simulator tooling accessible to AI agents through intelligent context engineering. **V3.0.0 adds platform-native `defer_loading` support** — Claude's tool search automatically discovers tools on-demand, minimizing baseline context overhead while maintaining full 29-tool functionality.

Why XC-MCP?

The Problem: Token Overflow Breaks MCP Clients

Traditional Xcode CLI wrappers dump massive output that exceeds MCP protocol limits:

  • simctl list: 57,000+ tokens (unusable in MCP context)
  • Build logs: 135,000+ tokens (catastrophic overflow)
  • Screenshot-first automation: 170 tokens per screen, 2000ms latency
  • No state memory between operations

The Solution: Progressive Disclosure + Accessibility-First

**V3.0.0 Architecture:**

Platform-native defer_loading on all 29 tools
├─ Claude's tool search discovers tools automatically
├─ Tools loaded on-demand (minimal baseline overhead)
├─ Accessibility-first workflow (50 tokens, 120ms vs 170 tokens, 2000ms)
└─ Workflow tools for common operations (fresh-install, tap-elem
