MCP Tools

MCP Tools for Swift Development

Model Context Protocol servers for enhanced Swift/Xcode workflows.

Available MCP Servers

1. XcodeBuildMCP

Purpose: Xcode project automation and build validation

Documentation: xcode-build-mcp.md

Key features:

• Discover Xcode projects and workspaces
• Build for macOS, iOS Simulator, iOS Device
• List schemes and show build settings
• Clean builds and derived data
• Create new projects from templates
• Autonomous build validation (AI can build, read errors, fix, rebuild)

Installation:

{
  "mcpServers": {
    "XcodeBuildMCP": {
      "command": "npx",
      "args": ["-y", "xcodebuildmcp@latest"]
    }
  }
}

Use when:

• After making code changes (MANDATORY validation)
• Debugging build issues
• Creating new Xcode projects
• Cleaning stale builds

2. Apple Docs MCP

Purpose: Official Apple documentation with offline WWDC access

Documentation: apple-docs-mcp.md

Key features:

• Search all Apple frameworks (SwiftUI, UIKit, Foundation, etc.)
• Get detailed symbol information (classes, methods, properties)
• WWDC sessions 2014-2025 with full transcripts (offline)
• Access Apple sample code
• Framework exploration and discovery
• API availability and deprecation checking

Installation:

{
  "mcpServers": {
    "apple-docs": {
      "command": "npx",
      "args": ["-y", "@kimsungwhee/apple-docs-mcp"]
    }
  }
}

Use when:

• Researching Apple APIs (PRIORITY over Context7)
• Finding WWDC best practices
• Checking API availability
• Getting official code examples

Workflow Integration

Research-First (MANDATORY)

Priority order:
1. ⭐ Apple Docs MCP (official Apple docs + WWDC)
2. Context7 (third-party libraries)
3. Exa web search (community tutorials)

Build Validation (MANDATORY)

After EVERY code change:
1. XcodeBuildMCP: Build project
2. If errors → Read error messages
3. Fix issues
4. Rebuild to validate
5. Only commit if zero errors

Complete Development Workflow (2026)

1. Feature request received
   ↓
2. Apple Docs MCP: Search API/WWDC
   ↓
3. Read existing codebase (DRY principle)
   ↓
4. Implement following Apple patterns
   ↓
5. XcodeBuildMCP: Build to validate ⭐
   ↓
6. If build errors:
   - Read error messages
   - Fix issues
   - Rebuild
   ↓
7. Run tests (if available)
   ↓
8. Commit changes
